ANNEX IXREQUIREMENTS APPLICABLE TO SIGNAL LIGHTS, RADAR INSTALLATIONS AND RATE-OF-TURN INDICATORS

PART IREQUIREMENTS CONCERNING THE COLOUR AND INTENSITY OF LIGHTSAND THE APPROVAL OF SIGNAL LANTERNSFOR INLAND WATERWAY VESSELS

CHAPTER 1DEFINITIONS

Article 1.01Signal lanterns

1.‘Lantern’ means a device for distributing the flux from an artificial light source; it also includes the components needed to filter, refract or reflect the light, and to hold or operate the light source.

2.Lanterns intended to give signals on board a vessel are called signal lanterns.

Article 1.02Signal lights

‘Signal lights’ means the light signals emitted by signal lanterns.

‘Masthead light’ means a white light, visible throughout a horizontal arc of 225° and projecting a uniform uninterrupted beam over 112° 30' on each side, i.e. from the bow to 22° 30' abaft the beam on each side.

‘Side lights’ means a green light to starboard and a red light to port; each of these lights shall be visible throughout a horizontal arc of 112° 30' and project a uniform uninterrupted beam, i.e. from the bow to 22° 30' abaft the beam.

‘Stern light’ means a white light, visible throughout a horizontal arc of 135° and projecting a uniform uninterrupted beam over a sector of 67° 30' along each side from the stern.

‘Yellow stern light’ means a yellow light, visible throughout a horizontal arc of 135° and projecting a uniform uninterrupted beam over a sector of 67° 30' along each side from the stern.

‘Light visible from all directions’ means a light visible throughout a horizontal arc of 360° and projecting a uniform uninterrupted beam.

(a)

‘Scintillating light’ means a light flashing at a rate of 40 to 60 light periods per minute.

(b)

‘Rapidly scintillating light’ means a light flashing at a rate of 100 to 120 light periods per minute.

A scintillating light is a series of regular light periods per unit time.

Signal lights are classified according to their luminous intensity as:

ordinary lights,
bright lights,
strong lights.

Article 1.03Light sources

‘Light sources’ means electrical or non-electrical devices designed to produce light fluxes in signal lanterns.

Article 1.04Optic

‘Optic’ means a device comprising refracting, reflecting, or refracting and reflecting components, including their holders. The function of these components is to direct the rays from a light source in new specific directions.

‘Coloured optic’ means an optic which modifies the colour and intensity of the light transmitted.

‘Neutral optic’ means an optic which modifies the intensity of the light transmitted.

Article 1.05Filter

‘Coloured filter’ means a selective filter which modifies the colour and intensity of the light transmitted.

‘Neutral filter’ means a non-selective component which modifies the intensity of the light transmitted.

Article 1.06Relation between I_O, I_B and t

I_O

means the photometric luminous intensity in candelas (cd) measured at normal voltage for electric lights.

I_B

means the operational luminous intensity in candelas (cd).

means the range in kilometres (km).

Taking into account, for example, the ageing of the light source, the degree of dirtiness of the optic and variations in the voltage of the on-board grid, I_B is taken as 25 % less than I_O.

Consequently:

I_B = 0,75 · I_O

The relation between I_B and t of signal lights is given by the following equation:

I_B = 0,2 · t² · q^-t

The atmospheric transmission coefficient q is taken as 0,76, corresponding to a meteorological visibility of 14,3 km.

AppendixEnvironment tests

1.Test concerning protection against splashing water and dust

1.1.The type of lantern protection shall be guaranteed in accordance with classification IP 55 of the IEC publication — Part 598-1.

The test concerning protection of the sample against splashing water and against dust, and the evaluation of the results, shall be carried out in conformity with IEC publication 529, classification IP 55.

The first ‘5’ stands for protection against dust. This means: full dust-proof protection of live components and protection against harmful deposits of dust. The penetration of dust is not completely prevented.

The second ‘5’ stands for protection against splashing water. This means that a water jet aimed at the lantern from all directions shall have no damaging effect.

1.2.The protection of the sample against water is evaluated as follows: the protection is considered to be adequate if any water which has entered has no detrimental effect on operation of the sample.

No water deposits shall have formed on the insulating materials, if this means that minimum vanishing point values could not be achieved. Live components shall not be wetted and shall not be affected by any water accumulating inside the lantern.

2.Humid atmosphere test

2.1.Purpose and application

This test is to determine the action of humid heat and of humidity during a change of temperature, as described in Article 3.01(10)(b), during operation or during transport or storage, on nautical installations, appliances and instruments, given that they could experience surface humidity from condensation.

This condensation is similar in the case of non-enclosed components to the action of a dust deposit or of a hygroscopic salt film forming during operation.

The following specification is based on IEC publication 68, Part 2-30 in conjunction with Article 3.01(10)(a) and (b). Additional information can be found in the publication.

Components and groups of components submitted non-enclosed for approval as type models shall be tested in that non-enclosed state or, if this is not possible given the nature of the components, by providing them with the minimum protection devices which the applicant considers necessary for use on board.

2.2.Execution

1.The test is conducted in a test chamber in which, if necessary by means of an air circulation device, the temperature and level of humidity are practically the same at all points.

During this temperature rise, the sample becomes damp.

8.The air temperature is maintained at + 40 ± 2 °C for a time period of 12 h ± 0,5 h measured from the start of phase 7, with a relative air humidity of 93 ± 3 %.

13.Not earlier than 10 hours after the start of phase 12 the air conditioning equipment of the sample is switched on. When the climatic data indicated by the manufacturer for the sample have been obtained, the sample is put into operation in accordance with the manufacturer's instructions and at the rated voltage of the on-board network, with a tolerance of ± 3 %.

14.After the time necessary to achieve normal operation in accordance with the manufacturer's instructions has elapsed, the functions are checked and the operating data of importance for use on board recorded and noted. If the chamber needs to be opened for this purpose, it shall be reclosed as quickly as possible.

If more than 30 minutes are required to reach normal operation, this phase shall be extended sufficiently so that, once the operating state has been reached, at least 30 minutes are available to monitor the functions and measure the operating data.

15.Within a period of one to three hours, with the sample again in service, the air temperature is lowered to ambient temperature, with a tolerance of ± 3 °C, and the relative humidity of the air to under 75 %.

16.The chamber is opened and the sample exposed to the normal temperature and humidity of the ambient air.

17.After 3 hours, and when all humidity visible on the sample has evaporated, the functions of the sample are monitored again, and operating data of importance for use on board recorded and noted.

18.The sample is subjected to a visual inspection. The body of the lantern is opened and the interior examined for any effects of the climatic test and for residual condensate.

This test is to determine the action of heat during operation, transport and storage, in accordance with Article 3.01(8)(a) and (10)(a). The following specification is based on IEC publication 68, Part 2-2 in conjunction with Article 3.01(10)(a). Additional information can be found in the IEC publication.

	Normal	Extreme
	Environment tests
Climate classes X and S	+ 55 °C	+ 70 °C
Climate classes X and S	Permissible tolerance ± 2 °C

The test under extreme ambient conditions shall, in principle, be performed first. If the operating data are within the tolerances applicable under normal ambient conditions, the normal ambient test may be dispensed with.

4.2.Execution

1.The test is conducted in a test chamber in which, if necessary by means of an air circulation device, the temperature is practically the same at all points.

The operating data for phases (2), (4) and (5) shall be within the tolerances permitted for the sample for normal ambient environment tests on the basis of these test and approval conditions.

5.Vibration test

5.1.Purpose and application

This test is to determine the functional and structural effects of the vibrations referred to in Article 3.01(10)(e). Structural effects concern the performance of the mechanical components, particularly vibrations by resonance and stress on materials leading to fatigue without necessarily producing direct effects on operation or changes in operating data.

The functional effects directly concern the operation and operating data of the sample. They may be linked to structural effects.

The following specification is based on IEC publication 68, Part 2-6 in conjunction with Article 3.01(10)(e). Values deviating from those in the abovementioned provisions are indicated by *. Additional information may be found in IEC publication 68, Part 2-6.

Test requirements:

The test shall be conducted with sinusoidal vibrations using the following frequencies with the amplitudes indicated:

	Normal	Extreme
	Environment tests
Vibration class V:
Frequencies	2 to 10 Hz	2 to 13,2 Hz*
Amplitude	± 1,6 mm	± 1,6 mm
Frequencies	10 to 100 Hz	13,2 to 100 Hz*
Acceleration amplitude	± 7 m/s²	± 11 m/s²

Samples intended to be used with shock-absorbing devices shall be tested with those devices. If, in exceptional cases, it is not possible to test with the shock-absorbers intended for normal operation, the appliances shall be tested without shock-absorbers and the stress modified to take account of the action of the shock-absorber.

A test without shock-absorbers is also acceptable for the determination of characteristic frequencies.

The vibration test shall be conducted in three main directions perpendicular to each other. For samples which on account of their construction may be subject to special stresses from vibrations at an oblique angle to the main directions, the test shall also be performed in the directions of special sensitivity.

5.2.Execution

1.Test apparatus

The test is conducted using a vibrating device known as a vibrating table, which enables the sample to be subjected to mechanical vibrations in accordance with the following conditions:

The basic movement shall be sinusoidal and such that the mounting points of the sample basically move in phase and along parallel lines.
The maximum amplitude of vibration of the lateral movement of any mounting point shall not exceed 25 % of the specified amplitude of the basic movement.
The relative importance of the spurious vibration, expressed by the formula
(in %)
where a₁ is the effective value of the acceleration produced by the frequency applied,
and where atot is the effective value of the total acceleration, including a₁, measured in the frequencies < 5 000 Hz,
shall not exceed 25 % at the mounting point taken as the point of reference for measurement of the acceleration.
The vibration amplitude shall not differ from its theoretical value by more than:
- ± 15 % at the mounting point taken as the point of reference and
- ± 25 % at any other mounting point.

In order to determine the characteristic frequencies, it must be possible to adjust the vibration amplitude in small steps between zero and the theoretical value.

The vibration frequency shall not differ from its theoretical value by more than
± 0,05 Hz for frequencies up to 0,25 Hz,
± 20% for frequencies higher than 0,25 Hz and up to 5 Hz,
± 1Hz for frequencies higher than 5 Hz and up to 50 Hz,
± 2% for frequencies higher than 50 Hz,

In order to compare the characteristic frequencies, it must be possible to adjust them at the beginning and end of the vibration test to within:

± 0,05 Hz for frequencies up to 0,5 Hz,
± 10%	± 0,5 Hz for frequencies up to 5 Hz,
	± 0,5 Hz for frequencies higher than 5 Hz and up to 100 Hz,
± 0,5% for frequencies higher than 100 Hz.

In order to scan the frequencies, it should be possible for the vibration frequency to vary continuously and exponentially in both directions between the lower and upper limits of the frequency ranges indicated in paragraph 5.1, with a scanning speed of 1 octave/minute ± 10 %.

In order to determine the characteristic frequencies, it must be possible to slow the speed of variation of the vibration frequency as desired.

The intensity of the magnetic field created by the vibration device in the vicinity of the sample should not exceed 20 kA/m. The testing authority may require lower permissible values for some samples.

2.First inspection, mounting and putting into service

The sample is inspected visually to verify that it is in impeccable condition as far as is apparent, and that the assembly is impeccable from the point of view of the construction of all the components and groups of components.

The sample is mounted on the vibrating table in accordance with the type of mount provided for on-board installation. Samples, the operation and performance of which under the influence of vibrations depend on their position in relation to the vertical, shall be tested in their normal operating position. The mounts and devices used for the mounting shall not noticeably modify the amplitude and the movements of the sample in the range of frequencies used in the test.

The sample is put into operation in accordance with the manufacturer's instructions at the rated voltage of the on-board network with a tolerance of ± 3 %.

After the time necessary to achieve normal operation has elapsed, the functions are checked and the operating data of importance for use on board recorded and noted.

3.Preliminary inspection of performance when subjected to vibrations

This test phase shall be conducted for all samples. For samples which may be used for different purposes with varying vibratory effects, the test shall be conducted for all or some of the various uses.

A frequency cycle is effected with the vibrating table so that the frequency range indicated in paragraph 5.1, with its corresponding amplitudes, is covered from the lowest frequency to the highest and conversely, at a rate of one octave per minute. The sample is observed during this operation using the appropriate means of measurement and visually, if necessary using a stroboscope, to check thoroughly for any operating problems, modifications of operating data and mechanical phenomena such as vibrations by resonance and rattling noises occurring in specific frequencies. These frequencies are described as ‘characteristic’.

If necessary, in order to determine characteristic frequencies and vibration effects, the frequency variation is slowed down, stopped or reversed and the amplitude of the vibrations reduced. During the gradual modification of the operating data, it is necessary to wait until the final value is reached while maintaining the vibration frequency, although not more than five minutes.

During the frequency scan, at least the frequencies and operating data of importance for use on board are recorded, and all characteristic frequencies are noted, with their effects, for subsequent comparison during phase (7).

If the response of the sample to mechanical vibrations cannot be adequately determined during operation, an additional vibration response test shall be performed without connecting the sample.

If during the frequency scan the operational data noticeably exceed the permissible tolerances, the operation is unacceptably disrupted or if the structural resonance vibrations are likely to cause destruction should the vibration test be continued, the test may be interrupted.

4.Test of switching functions

This test phase shall be conducted for all samples where vibratory stress may influence switching functions, for example relays.

The sample is subjected to vibrations in the frequency ranges indicated in paragraph 5.1 with frequency variation steps in accordance with the E-12 series(2) and the corresponding amplitudes. At each frequency step, all switching functions which may be sensitive to vibration, if necessary including switching-on and switching-off, are carried out at least twice.

Switching functions may also be tested at frequencies occurring between the E-12 series values.

5.Extended test

This test phase shall be conducted for all samples. For samples which may be used for different purposes with varying vibratory effects, the first part of this phase (when the sample is in service) may be conducted several times, for all or some of the various uses.

When the sample is in service as described in phase (2) above, it is subjected to five cycles during which the frequency range indicated as stress producing in paragraph 5.1, with the corresponding amplitudes, is covered each time from the lowest to the highest frequency and conversely, at a rate of one octave per minute.

After the fifth cycle, the vibrating table may be stopped, the functions are tested and the operating data of importance for on-board use recorded and noted.

6.Fixed frequency extended test

This test phase shall be conducted if, on examining vibratory performance during phase (3) above, mechanical resonances are observed during the scan of the frequency range above 5 Hz, which are acceptable for extended use on board according to the manufacturer or his authorised representative, but for which the strength of the parts concerned cannot be taken for granted. In particular, this phase concerns appliances fitted with shock absorbers with a resonance frequency within the frequency range indicated in paragraph 5.1 and higher than 5 Hz.

When the sample is in service as described in phase 2 above, for each resonance frequency concerned, it is subjected for two hours to vibrations at the amplitude provided for in the extreme ambient test and at the corresponding frequency as referred to in paragraph 5.1, the direction of vibration being that which in normal use exerts the maximum stress on the parts in question. If necessary, the frequency applied must be rectified so that the resonance vibrations continue at not less than 70 % of their maximum amplitude, or the frequency must be made to vary continuously between two values 2 % below and 2 % above the resonance frequency initially observed, at a rate of at least 0,1 but not more than 1 octave per minute. During the vibratory stress, the functions of the sample are monitored until malfunctions begin to occur, as a result of mechanical parts becoming detached or displaced or of a break in the electrical connection or of a short-circuit.

Samples for which the execution of this test phase is relevant when switched off may be tested in that state, provided the mechanical stress on the parts concerned is not less than in normal use.

7.Final inspection of performance when subjected to vibration

This test phase must be effected as necessary.

The inspection of performance when subjected to vibrations referred to in phase 3 is repeated using the frequencies and amplitudes applied in that phase. The characteristic frequencies observed and the observed effects of vibration stress are compared with the results of phase 3 in order to determine any changes which occurred during the vibration test.

8.Conclusions of the inspection

Once the vibrating table has stopped and the time necessary to arrive at an operating state without vibratory stress has elapsed, the functions are tested and the operating data of importance for on-board use recorded and noted.

Lastly, the sample is inspected visually to verify that it is in impeccable condition.

5.3.Results to be obtained

The sample and its components and groups of components should not show any mechanical resonance vibrations in the frequency ranges indicated in paragraph 5.1. When resonance vibrations of this type are unavoidable, construction measures must be taken to ensure that the sample, its components and groups of components suffer no damage.

During and following the vibration test, no perceptible effect of vibratory stress shall occur, and in particular no difference between the characteristic frequencies observed in phase 7 and the values determined in phase 3 and no damage or malfunction as a result of extended vibration shall be observed.

In the case of the normal ambient test, the operating data recorded in phases 3 to 8 shall remain within the tolerances permitted on the basis of these test and approval conditions.

During the switching functions test in phase 4, no switching malfunction or breakdown shall occur.

6.Accelerated weather resistance test

6.1.Purpose and application

The accelerated weather resistance test (simulation of exposure to the elements through exposure to radiation from xenon lamps with filters and by sprinkling) is conducted in accordance with Parts 2-3, 2-5 and 2-9 of IEC publication 68 plus the following additions:

According to this publication, the accelerated weather resistance test aims at simulating natural weather conditions by means of a test apparatus under specific reproducible conditions, so as to provoke rapid changes in the properties of the materials.

The accelerated test is carried out in a test apparatus with filtered radiation from xenon lamps and intermittent sprinkling. Following exposure to the elements, measured by the product of the intensity of radiation and its duration, the agreed properties of the samples are compared with those of samples of the same origin which have not been exposed to the elements. First to be specified are the properties crucial for practical use, such as colour, surface quality, shock resistance, tensile strength and solidity.

In order to compare the results with those of exposure to natural weather conditions, it is assumed that the alteration of properties by the elements is caused in particular by natural radiation and the simultaneous action of oxygen, water and heat on the materials.

For the accelerated test, particular account must be taken of the fact that the radiation in the appliance is very close to natural radiation (see the IEC publication). The radiation from the xenon lamp with a special filter simulates natural radiation.

Experience has shown that, under the test conditions indicated, there is a strong correlation between resistance to weather in the accelerated test and resistance to natural weather conditions. The accelerated test, which is independent of place, climate and season, has the advantage over natural weather conditions of being reproducible and of making it possible to shorten the duration of the test as it is independent of the alternation of day and night and of the seasons.

6.2.Number of samples

For the weather-resistance test, unless otherwise agreed, an adequate number of samples is used. An adequate number of samples not subjected to weather conditions is required for the purposes of comparison.

6.3.Preparation of samples

The samples are subjected to the tests in the state in which they are delivered, unless otherwise agreed. The samples to be used for comparison are kept in the dark at ambient temperature throughout the tests.

6.4.Test apparatus

The test apparatus consists basically of a ventilated test chamber with the radiation source in the centre. Optical filters are placed round the radiation source. The sample mounts are rotated around the longitudinal axis of the system at the required distance from the source and the filters to reach the intensity of radiation prescribed in paragraph 6.4.1.

The intensity of the radiation on any component of the total sample surfaces exposed shall not differ by more than ± 10 % from the arithmetical mean of radiation intensity on the various surfaces.

6.4.1.Radiation source

A xenon lamp is used as the radiation source. The radiation flux shall be selected so that the intensity of radiation on the sample surface is 1 000 ± 20O W. m^-2 in the 300 to 830 nm waveband (see paragraph 6.9 for the apparatus for measuring irradiation).

If air-cooled xenon lamps are used, the air already used containing ozone must not enter the test chamber and must be evacuated separately.

The experimental values show that the radiation flux from xenon lamps drops to 80 % of its initial value after approximately 1 500 hours of operation; after this period, the proportion of ultra-violet radiation is also reduced noticeably compared with other forms of radiation. The xenon lamp must therefore be replaced after this period (see also the data supplied by the xenon lamp manufacturer).

6.4.2.Optical filters

Optical filters must be positioned between the radiation source and the sample mounts so that the filtered radiation from the xenon lamps is as close as possible to natural radiation (see IEC publication 68, Parts 2 to 9).

All glass filters must be cleaned regularly to avoid any undesirable decrease in radiation intensity. The filters must be replaced if the similarity to natural radiation can no longer be achieved.

With regard to appropriate optical filters, the data supplied by the manufacturer of the test apparatus must be complied with. On delivery of test apparatus, the manufacturer must guarantee that it meets the requirements set out in paragraph 6.4.

6.5.Sprinkling and air humidifying device

The sample shall be wetted in such a way that the action is the same as that of natural rain and dew. The sample sprinkling device shall be so constructed that during sprinkling all the external surfaces of the samples are wetted. It must be controlled in such a way that the sprinkling/dry-period cycle prescribed in paragraph 6.10.3 is complied with. The air in the test chamber must be humidified so as to maintain the relative humidity prescribed in paragraph 6.10.3. The water used for sprinkling and for humidifying the air must be distilled water or fully desalinated water (conductivity < 5 μS/cm).

The tanks, pipes and sprayers for distilled or fully desalinated water must be of corrosion-resistant materials. The relative humidity of the air in the test chamber is measured using a hygrometer protected against sprinkling and direct radiation and is adjusted by means of the hygrometer.

When fully desalinated water or water in a closed circuit is used the risk exists (as in the varnish test) of the formation of a deposit on the surface of the samples or of wear on the surface by substances in suspension.

6.6.Ventilation device

The temperature of the black panel prescribed in paragraph 6.10.2 is maintained in the test chamber by the circulation of clean, filtered, humidified and, if necessary, temperature-controlled air over the samples. The flow and speed of the air shall be selected so as to ensure uniform tempering of all external surfaces of the mounts of the samples in the system.

6.7.Sample mounts

Any mounts in stainless steel enabling the samples to be mounted as set out in paragraph 6.10.1 may be used.

6.8.Blackpanel thermometer

In order to measure the temperature of the black panel during the dry period of the cycle, a blackpanel thermometer is used. This thermometer consists of a stainless steel panel thermally insulated from its mounts, the same size as the sample mounts and 0,9 ± 0,1 mm thick. The two sides of the panel are covered with shiny black varnish which is highly weather-resistant and has a maximum reflecting power of 5 % at wave-lengths of more than 780 nm. The temperature of the panel is measured using a bimetallic thermometer the sensor of which is placed in the middle of the panel with a good thermal contact.

It is not advisable to leave the thermometer in the apparatus throughout the test referred to in paragraph 6.10. It is sufficient for it to be inserted into the test apparatus every 250 hours, for 30 minutes or so, and for the temperature of the black panel to be taken during the dry period.

6.9.Irradiation measuring apparatus

Irradiation (unit of measurement: W. s m-2) is the product of the intensity of irradiation (unit: W. m-2) and duration of irradiation (unit: s). The irradiation of the surfaces of the sample in the test apparatus is measured with an appropriate irradiation measuring apparatus, adapted to the radiation function of the system consisting of the radiation source and the filter. The irradiation measuring apparatus shall be graduated or calibrated so that infra-red radiation over 830 nm is not taken into account.

The capacity of the irradiation measuring apparatus depends basically on whether its sensor is highly resistant to weather and to ageing and has adequate spectral sensitivity to natural radiation.

The irradiation measuring apparatus may include the following parts, for example:

(a)

a silicon photo-electric cell as radiation sensor;

(b)

an optical filter placed in front of the photo-electric cell; and

(c)

a coulometer which measures the product (unit: C = A.s) of the intensity of the current produced in the photo-electric cell in proportion to radiation intensity (unit: A) and the duration of radiation (unit: s).

The scale of the irradiation measuring apparatus shall be calibrated. The calibration shall be checked after being used for a year and corrected if necessary.

The intensity of irradiation on the surface of samples depends on the distance from the radiation source. Sample surfaces shall therefore, as far as possible, be at the same distance from the source as the sensor of the irradiation measuring apparatus. If this is not possible, the irradiation reading on the measuring apparatus shall be multiplied by a correction factor.

6.10.Execution

6.10.1.The samples are placed in mounts so that water cannot collect on the rear surface. The sample mounts must cause only the smallest possible amount of mechanical stress. In order to ensure irradiation and sprinkling are as evenly distributed as possible, the samples are rotated during the test at a rate of one to five revolutions per minute round the source-filter system and the sprinkling device. Normally, a single side of the sample is exposed to the weather conditions. Depending on the applicable provisions of the IEC publication, or as otherwise agreed, the front and back surfaces of a single sample may also be exposed. In this case, each surface is exposed to the same radiation and the same sprinkling.

The exposure of the front and back surfaces of a given sample to the same radiation and sprinkling may be produced by the periodic rotation of the sample. This can be done automatically using rotating appliances if the mount is in the form of an open frame.

6.10.2.The temperature of the black panel at the point where the samples are placed during the dry period is set and regulated in accordance with the IEC publications applicable to the equipment in question. Unless otherwise agreed, the average temperature of the black panel must be kept at + 45 °C. Average temperature of the black panel means the arithmetic mean of the black panel temperature reached at the end of the dry period. During the dry period, a local difference of ± 5 °C is permissible, and ± 3 °C in borderline cases.

In order to maintain the required temperature of the black panel and, when necessary, ensure radiation of equal intensity on the front and back surfaces of the sample (see paragraph 6.10.1), the samples may be turned automatically through 180° after each revolution. In this case, the blackpanel thermometer and the irradiation measuring apparatus shall be included in the rotation movement.

6.10.3.Samples installed in mounts and the sensor of the irradiation measuring apparatus referred to in paragraph 6.9 are evenly exposed to radiation and sprinkled according to the cycle defined below, which is repeated successively:

Sprinkling

3 minutes

Dry period:

17 minutes

The relative humidity of the air must be 60 to 80 % during the dry period.

6.11.Test duration and procedure

The test follows procedure B in IEC publication 68, Part 2-9. The test duration is 720 hours, with the sprinkling cycle defined in paragraph 6.10.3.

It is recommended that the weather-resistance test should be carried out with one and the same sample (in the case of a non-destructive test of the modification of the properties to be considered, such as the weather-resistance test, for example) or with several samples (in the case of a destructive test, as for shock-resistance, for example) at various degrees of irradiation, to be agreed upon. The development of the modification of the properties of a piece of equipment throughout the weather test can therefore be determined.

6.12.Assessment

After the exposure to bad weather is completed, the sample is kept for at least 24 hours in darkness in an air temperature of +23 °C, a dew point of +12 °C, a relative air humidity of 50 %, an air circulation speed of 1 m/s and an atmospheric pressure of 860 to 1060 hPa. (The permissible difference may be ± 2 °C for the air temperature and ± 6 % for the relative humidity.)

These samples and those used for the comparison referred to in paragraphs 6.2 and 6.3 are inspected to determine properties in accordance with the requirements indicated in Article 2.01(1) and (2) and in Article 3.01(12).

7.Salt water and weather-resistance test

(sea-fog test)

7.1.Purpose and application

This test is to determine the action of salt water and a saline atmosphere during operation and during transport and storage in accordance with Article 3.01.

It may be restricted to the sample or to specimens of the materials used.

The following specifications are based on IEC publication 68, Part 2-52. Additional information can be found in the publication.

7.2.Execution

1Test apparatus

The test is conducted in a test chamber using an atomiser and a saline solution meeting the following conditions:

the materials of the test chamber and the atomiser must not influence the corrosive action of the salt mist,
a fine, homogeneous, wet, thick mist must be diffused inside the test chamber; the distribution must not be affected by eddies or by the presence of the sample. The jet must not touch the sample directly. Drops forming on the inside of the chamber must not be able to fall on the sample;
the test chamber must be adequately ventilated and the ventilation outlet protected against sudden changes in the movement of the air, so as to prevent the formation of a strong air current in the chamber,
the saline solution used must consist, by mass, of 5 ± 1 parts of pure sodium chloride, with a maximum of 0,1 % sodium iodide and 0,3 % impurities, in the dry state, to 95 ± 1 parts of distilled or fully desalinated water. Its pH must be between 6,5 and 7,2 at a temperature of + 20 ± 2 °C and be kept within these limits during the operation. Solution once sprayed must not be reused,
the compressed air used for spraying must be free of impurities such as oil or dust and shall have a humidity level of at least 85 % in order to avoid blockage of the nozzle,
the mist diffused in the chamber must have a density such that, in a clean receptacle with an open horizontal surface area of 80 cm², placed anywhere in the chamber, the average precipitation over the whole time is between 1.0 ml and 2.0 ml per hour. In order to monitor the density of the mist, at least two receptacles shall be placed in the chamber in such a way as not to be covered by the sample and not to receive drops of condensation. In order to calibrate the quantity of solution sprayed, the duration of spraying shall be at least eight hours,
the period of humidity between phases of spraying is spent in an air-conditioned chamber in which the air can be kept at a temperature of + 40 ± 2 °C and at a relative humidity of 93 ± 3 %.

2.Preliminary inspection

The sample is inspected visually to verify that it is in impeccable condition, and in particular that it is correctly assembled and that all openings close properly. External surfaces soiled with grease, oil or mud are cleaned. All controls and moving parts are manipulated and checked for proper operation. The mobility of all closures, covers and moving parts intended to be detached or moved during operation or maintenance must be inspected for mobility and correctly replaced.

The sample is put into operation in accordance with the manufacturer's instructions at the rated voltage of the on-board network with a tolerance of ± 3 %.

After the time required to reach normal operation has elapsed, the functions are tested and the operating data of importance for on-board use and for assessing the action of the salt mist atmosphere are recorded and noted. The sample is then disconnected for exposure to spraying.

3.Spraying phase

The sample is put into the salt mist chamber and exposed to the salt mist for two hours at a temperature of +15 °C to +35 °C.

4.Humidity period

The sample is placed in the air-conditioned chamber so that the least possible amount of saline solution drips from it. It is kept in the air-conditioned chamber for seven days, at an air temperature of + 40 ± 2 °C and a relative humidity of 93 ± 3 %. It must not come into contact with any other sample or metal object. Several samples may be so arranged as to preclude any mutual influence.

5.Repetition of the test cycle

The test cycle, including phases 3 and 4, is repeated three times.

6.Subsequent treatment

Following the fourth test cycle, the sample is taken out of the air-conditioned chamber and immediately washed for five minutes in running tap water and rinsed in distilled or desalinated water. Drops adhering to the sample are removed by an air jet or shaken off.

The sample is exposed to the normal ambient atmosphere for at least three hours, and in any case long enough for any visible humidity to have evaporated, before being subjected to a final inspection. The sample is dried for an hour at + 55 ± 2 °C after rinsing.

7.Conclusions of the inspection

The external appearance of the sample is inspected visually. The nature and extent of deterioration from its initial state are recorded in the test report, with supporting photographs if necessary.

The sample is put into operation in accordance with the manufacturer's instructions at the rated voltage of the on-board network with a tolerance of ± 3 %.

All controls and moving parts are manipulated and checked for proper operation. The mobility of all closures, covers and moving parts intended to be detached or moved during operation or maintenance is checked.

7.3.Results to be obtained

The sample must not show any change which could:

hinder its use and operation,
prevent to any considerable extent the detachment of closures and covers, or the movement of moving parts in so far as this is necessary for use or maintenance,
impair the waterproofness of the housing,
be expected to cause malfunctions in the long run.

The operating data recorded in phases 3 and 7 must remain within the tolerances laid down in these test and approval conditions.
