Directive of the European Parliament and of the Council of 12 December 2006 laying down technical requirements for inland waterway vessels and repealing Council Directive 82/714/EEC (2006/87/EC) (repealed)

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

CHAPTER 1 DEFINITIONS

Article 1.01 Signal 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 1.02 Signal lights

1.

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

2.

‘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.

3.

‘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.

4.

‘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.

5.

‘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.

6.

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

7.

(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.

8.

Signal lights are classified according to their luminous intensity as:

• ordinary lights,

• bright lights,

• strong lights.

Article 1.03 Light sources

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

Article 1.04 Optic

1.

‘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.

2.

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

3.

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

Article 1.05 Filter

1.

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

2.

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

Article 1.06 Relation 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).

t

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.

CHAPTER 2 REQUIREMENTS FOR SIGNAL LIGHTS

Article 2.01 Colour of signal lights

1. A five-colour signal system shall apply to the lights, comprising the following colours:

• white,

• red,

• green,

• yellow,

• blue.

This system shall conform to the recommendations of the International Commission on Illumination, ‘Colours of Signal Lights’, IEC publication No 2.2. (TC-1.6) 1975.

The colours shall apply to the light fluxes emitted by the signal lantern.

2. The colour boundaries of signal lights shall be demarcated by the coordinates of the intersecting points of the chromatic diagram in IEC publication No 2.2 (TC-1.6) 1975 (see chromaticity diagram) as follows:

However, for daytime use of the yellow scintillating lights a minimum luminous intensity (I_O) of 900 cd shall apply.

Article 2.03 Signal light dispersion

1. Horizontal dispersion of the luminous intensity

1.1.

The luminous intensities indicated in Article 2.02 shall apply to all directions of the horizontal plane passing through the focus of the optic or the luminous centre of gravity of the correctly adjusted light source of a vertically positioned signal lantern.

1.2.

For the masthead lights, stern lights and side lights, the luminous intensities prescribed shall be maintained throughout the horizontal arc within the sector prescribed at least up to within 5° of the limits.

As from 5° within the sector prescribed up to the limit, the luminous intensity may decrease by 50 %; it shall subsequently decrease gradually in such a way that, as from 5° beyond the limits of the sector, only a negligible amount of light remains.

1.3.

The side lights shall have the prescribed luminous intensity in the direction parallel to the axis of the vessel forward. The intensities shall decrease practically to zero between 1° and 3° beyond the limits of the prescribed sector.

1.4.

For bi-coloured or tri-coloured lanterns, the dispersion of the luminous intensity shall be uniform so that 3° on either side of the prescribed sector limits, the maximum permitted intensity is not exceeded and the minimum prescribed intensity is reached.

1.5.

The horizontal dispersion of the luminous intensity of the lanterns shall be uniform throughout the sector, so that the minimum and maximum values observed for the photometric luminous intensity do not differ by more than a factor of 1,5.

2. Vertical dispersion of the luminous intensity

In the event of heeling of up to ± 5° or ± 7,5° from the horizontal, the luminous intensity shall remain at least equal to 80 % in the first case, and 60 % in the second case, of the luminous intensity corresponding to 0° heeling, although it shall not exceed it by more than 1,2 times.

CHAPTER 3 REQUIREMENTS FOR SIGNAL LANTERNS

Article 3.01 Technical requirements

1. The construction of and materials of signal lanterns and light sources shall be such as to ensure their safety and durability.

2. The components of the lanterns (for example, the cross braces) shall not impair the intensity, colours or dispersion of the light.

3. It shall be possible to install the signal lanterns on board simply and in the correct position.

4. It shall be easy to replace the light source.

CHAPTER 4 TESTS, APPROVAL AND MARKINGS

Article 4.01 Type tests

The type test according to the ‘Conditions for testing and approval of signal lanterns in inland waterway vessels’ is intended to ascertain whether the signal lanterns and their light source meet these requirements.

Article 4.02 Test procedure

1. An application for a type test shall be submitted to the competent testing authority, with at least two copies of the plans and two specimens of the lantern as well as the light sources required.

2. If the test does not give rise to objections, one copy of the plans accompanying the application, with the approval entered on it, and one of the approved specimen lanterns shall be returned to the applicant. The second copy and second specimen lantern shall be kept by the testing authority.

3. The manufacturer shall declare to the testing authority that all the components of the series-produced lantern conform to those of the type-tested lantern.

Article 4.03 Approval certificate

1. If the type test shows that these requirements have been met, the signal lantern type shall be approved and an approval certificate based on the model in the Appendix and bearing the markings referred to in Article 4.05 shall be issued to the applicant.

2. The holder of the approval certificate:

• shall be authorised to affix the markings referred to in Article 4.05 to the various parts;

• may undertake manufacture only in conformity with the plans approved by the testing authority and according to the technique used for the type-tested lanterns;

• may modify the approved plans and lantern models only with the approval of the testing authority. The latter shall also decide whether the approval certificate issued only requires additions to be made to it or whether a new application for approval is needed.

Article 4.04 Spot checks

1. The testing authority shall be empowered to take samples of signal lanterns from the production series for testing.

2. If the test reveals serious shortcomings, the approval may be withdrawn.
