19、tural 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:a) fuel containers;b) stationary gas engines;c) container mounting hardware;d) electronic fuel management;e) refuelling receptacles.NOTE 1 It

20、 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

21、 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 MP

22、a (20 bar) working pressure system will require pressures to be multiplied by 1,25.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
