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laying down technical requirements for inland waterway vessels and repealing Council Directive 82/714/EEC (2006/87/EC) (repealed)

Article 9.20 Electronic equipment

1. General

The test conditions in paragraph 2 below shall apply only to electronic devices that are necessary for the steering system and the craft's power plants, including their ancillaries.

2. Test conditions

(a) The stresses arising from the following tests shall not cause electronic devices to be damaged or to malfunction. The tests in accordance with relevant international standards, such as IEC publication 60092-504:2001, apart from the cold-condition test, shall be carried out with the device switched on. These tests shall include checking of proper operation.

(b) Variations in voltage and frequency

		Variations
		continuous	short-duration
General	Frequency	± 5 %	± 10 % 5 s
	Voltage	± 10 %	± 20 % 1.5 s
Battery operation	Voltage	+ 30 %/- 25 %

(c) Heating test

The sample is brought up to a temperature of 55 °C within a half-hour period. After that temperature has been reached it is maintained for 16 hours. An operating test is then carried out.

(d) Cold-condition test

The sample is switched off and cooled to -25 °C and held at that temperature for two hours. The temperature is then raised to 0 °C and an operating test is carried out.

(e) Vibration test

The vibration test shall be carried out along the three axes at the resonance frequency of the devices or of components for the period of 90 minutes in each case. If no clear resonance emerges the vibration test shall be carried out at 30 Hz.

The vibration test shall be carried out by sinusoidal oscillation within the following limits:

General:

f = 2,0 to 13,2 Hz; a = ± 1 mm

(amplitude a = the vibration width)

f = 13,2 Hz to 100 Hz: acceleration ± 0,7 g.

Equipment intended to be fitted to diesel engines or steering apparatus shall be tested as follows:

f = 2,0 to 25 Hz; a = ± 1,6 mm

(amplitude a = the vibration width)

f = 25 Hz to 100 Hz; acceleration ± 4 g.

The sensors intended to be installed in diesel-engine exhaust pipes may be exposed to considerably higher stresses. Account shall be taken of this during the tests.

(f) The electromagnetic compatibility test shall be carried out on the basis of IEC publications 61000-4-2:1995, 61000-4-3:2002, 61000-4-4:1995, at test degree number 3.

(g) Proof that the electronic equipment is adequate for these test conditions shall be provided by their manufacturer. A certificate by an approved classification society shall likewise be considered to be proof.
