标准范围

This part of ISO 12614 specifies tests and requirements for the rigid fuel line in copper, a liquefiednatural 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) refueling receptacles.NOTE 1 It is recognized that miscellaneous components not specifically covered herein can be examined tomeet 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 unlessotherwise 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 thepressure by the appropriate factor (ratio). For example, a 2 MPa (20 bar) working pressure system will requirepressures to be multiplied by 1,25.
