Scope
This part of ISO 12614 specifies tests and requirements for the pressure regulator, a liquefied natural gas fuel system component intended for use on the types of motor vehicles defined in ISO 3833. This part or dual-fuel applications). It is not applicable to the following: 1) fuel containers; 2) stationary gas engines; 3) container mounting hardware; 4) electronic fuel management; 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 bar).
(1 bar = 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, a 2 MPa (20 bar) working pressure system will require pressures to be multiplied by 1,25.
