Endurance test. The gas tube and its coupling(s) shall be tested for an endurance test consisting out of 100,000 cycles. One cycle consist out of pressure ramp from 15 per cent·WP up to WP. After the endurance test, the gas tube and its coupling(s) need to comply with the leakage test of Annex 16, paragraphs 5., 6. and 7 and with the overpressure test according to Annex 16, paragraph 4.
Endurance test. 6.5.1. The audible reverse warning device shall be supplied with current at the rated voltage and with the connecting lead resistances specified in paragraphs 6.3.4. to 6.3.6. above.
Endurance test. Either The audible reverse warning device(s) fitted on the vehicle has been of a type approved under this Part I of this Regulation or The audible reverse warning device(s) fitted on the vehicle, which has not been of a type approved under Part I of this Regulation, has (have) to fulfil the "Endurance test" of paragraph 6.5. except 6.5.6. and 6.6. of this Regulation. After this test the audible reverse warning device(s) shall pass the test according to Part II of this regulation.
Endurance test. 6.4.1. The audible warning device, audible warning system, multiple audible warning system shall be supplied with current at the rated voltage and with the connecting lead resistances specified in paragraphs 6.3.4. to 6.3.6. above, and operated respectively: 10,000 times for audible warning device, audible warning system, multiple audible warning system intended principally for vehicles of categories L3 to L5 with a power less than or equal to 7 kW. 50,000 times for audible warning device, audible warning system, multiple audible warning system intended principally for vehicles of categories M, N and L3 to L5 with a power greater than 7 kW, each time for one second followed by an interval of 4 s. During the test, the audible warning device, audible warning system, multiple audible warning system shall be ventilated by an air current having a speed of approximately 10 m/s and the electro-pneumatic audible warning device, audible warning system, multiple audible warning system may be lubricated with the oil recommended by the manufacturer after every 10,000 times of operation.
Endurance test. 6.3.1. The warning device shall be supplied with current at the rated voltage and with the connecting lead resistances specified in paragraphs 6.2.3. to 6.2.5. above, and operated 50,000 times, each time for one second followed by an interval of four seconds. During the test, the device shall be ventilated by an air current having a speed of approximately 10 m/sec.
Endurance test. 9.1. A filling unit or service valve shall be capable of conforming to the applicable leakage test requirements of paragraphs 5. and 8. above, after being subjected to a number of cycles of opening and closing as mentioned in the annexes to this Regulation.
