Part 3 - Specifications for Environmental testing for Type Approval of Pollution Prevention Equipment

 The specifications for environmental testing for type approval relate to the electrical and electronic sections of:

• .1 15 ppm Bilge Separator; and

• .2 15 ppm Bilge Alarm.

 The above-mentioned items, hereafter referred to as "equipment", when tested should comply with all the relevant requirements contained in section 5 of these Guidelines and Specifications.

  3.2.1 Testing requirements

 The electrical and electronic sections of the equipment in the standard production configuration should be subjected to the programme of environmental tests set out in this Specification at a laboratory approved for the purpose by the Administration or by the competent authority of the manufacturer's home country. A copy of the environmental test document, in a format similar to that specified in section 2 of part 5 of this annex, should be submitted to the Administration by the manufacturer, together with the application for type approval.

  3.2.2 Test specification details

 Equipment should operate satisfactorily on completion of each of the following environmental tests:

  .1 Vibration tests:

• .1.1 a search should be made for resonance over the following range of frequency and amplitude of acceleration:

  • .1.1.1 2 to 13.2 Hz with an amplitude of ± 1mm; and

  • .1.1.2 13.2 to 80 Hz with an acceleration of ± 0.7 g.

  This search should be made in each of the three planes at a rate sufficiently low to permit detection of resonance;

• .1.2 the equipment should be vibrated in the planes at each major resonant frequency for a period of 2 hours;

• .1.3 if there is no resonant frequency, the equipment should be vibrated in each of the planes at 30 Hz with an acceleration of ± 0.7 g for a period of 2 hours;

• .1.4 after completion of the tests specified in .1.2 or .1.3 of this paragraph a search should again be made for resonance and there should be no significant change in the vibration pattern.

  .2 Temperature tests:

• .2.1 equipment that may be installed in an enclosed space that is environmentally controlled, including an engine-room, should be subjected, for a period of not less than 2 h, to:

  • 2.1.1 a low temperature test at 0°C; and

  • 2.1.2 a high temperature test at 55°C.

  At the end of each of the tests referred to, the equipment should be switched on and it should function normally under the test conditions.

  .3 Humidity tests:

Equipment should be left switched off for a period of 2 h at a temperature of 55°C in an atmosphere with a relative humidity of 90%. At the end of this period the equipment should be switched on and should operate satisfactorily for 1 hour;

  .4 Inclination test:

Equipment should operate satisfactorily at angles of inclination up to 22.5° in any plane from the normal operating position;

  .5 Reliability of electrical and electronic equipment:

The electrical and electronic components of the equipment should be of a quality guaranteed by the manufacturer and suitable for their intended purpose.
