This part of ISO 12614 specifies tests and requirements for the pressure relief valve (PRV), a liquefied natural gas fuel system component intended for use on the types of motor vehicles defined in ISO 3833. This part of ISO 12614 is not applicable to the following:

  1. fuel containers;

  2. stationary gas engines;

  3. container mounting hardware;

  4. electronic fuel management;

  5. refueling receptacles.

NOTE 1

It is recognized that miscellaneous components not specifically covered herein can be examined to meet the criteria of this part of ISO 12614 and tested according to the appropriate functional tests.

NOTE 2

All references to pressure in this part of ISO 12614 are to be considered gauge pressures unless otherwise specified.

NOTE 3

This part of ISO 12614 is based upon a working pressure for natural gas as a fuel of 1,6 MPa [16 bar1

1

1bar = 0,1 MPa = 105 Pa; 1 MPa = 1 N/mm2.

]. Other working pressures can be accommodated by adjusting the pressure by the appropriate factor (ratio). For example, 2 MPa (20 bar) working pressure system will require pressures to be multiplied by 1,25.
