34、 or, if the automatic valve is closed during commanded stop phases, the valve shall ISO 2017 All rights reserved 3BS ISO 12619-6:2017ISO 12619-6:2017(E)be submitted to the following numbers of operations during testing according to ISO 12619-2 but lower the downstream pressure of the test fixture to
35、 less than 2 % of working pressure:a) 200 000 cycles (mark “H1”) if the engine shuts off automatically when the vehicle comes to a halt;b) 500 000 cycles (mark “H2”) if, in addition to a), the engine also shuts off automatically when thevehicle drives with the electric motor only;c) 1 000 000 cycles
36、 (mark “H3”) if, in addition to a), the engine also shuts off automatically when theaccelerator pedal is released.Notwithstanding the above-mentioned provisions, the valve complying with b) shall be deemed to satisfy a), and the valve complying with c) shall be deemed to satisfy a) and b).Perform th
37、e leakage test in accordance with 6.3. The valve shall continue to operate according to the manufacturer specifications.6.4.2 Following cycling and leakage testing, perform the hydrostatic strength test in accordance with 6.2.6.5 Insulation resistanceThe insulation resistance test is designed to che
38、ck for a potential failure of the insulation between the two-pin coil assembly and the automatic valve casing.Apply DC 1 000 V between one of the connector pins and the housing of the automatic valve for at least 2 s. The minimum allowable resistance shall be 240 k.If the automatic valve is electric
39、ally operated and is to be used inside a gas-tight housing, it shall be intrinsically safe as defined in IEC 60079-10-1.6.6 Minimum opening voltageThe minimum opening voltage at room temperature shall be 8 V for a 12 V system and 16 V for a 24 V system. The component shall be pressurized at minimum
40、0,75 times working pressure during the test.6.7 Pressure impulseThe automatic valve that is exposed in service to cylinder pressure, shall withstand 100 pressure pulses, as follows.a) If the automatic valve is external, connect both inlet and outlet to a pipe or tube of the type specifiedby the manu
41、facturer and of at least 1 m in length each.b) If the automatic valve is mounted to or inside the cylinder valve, the cylinder valve containingthe automatic valve shall be connected securely by a suitable fitting to a pressurized source ofdry air, nitrogen or natural gas. Connect the outlet to a pip
42、e or tube of the type specified by themanufacturer and of at least 1 m in length each.c) The outlet of the automatic valve shall be vented until the inlet is at atmospheric pressure, and thenthe outlet of the valve shall be closed.d) Working pressure shall be instantaneously applied to the inlet.e)
43、Test the component in the same way with reverse flow direction.Following the pressure impulse test, the automatic valve should operate according to the manufacturers specification.This test was included in order to evaluate the performance of the components that may suffer from the effects of an ins
44、tantaneous increase in pressure. In normal service, this may happen, for example, when filling gas in an empty system or when a solenoid valve opens the flow of gas to an empty fuel line. 4 ISO 2017 All rights reservedBS ISO 12619-6:2017ISO 12619-6:2017(E)Previous tests have revealed that certain de
45、signs cannot cope with these instantaneous pulses and the components tend to bend or jam.
