标准范围

This part of ISO 12614 specifies tests and requirements for the differential pressure fuel content gauge,a liquefied natural gas fuel system component intended for use on the types of motor vehicles defined inISO 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 maximum working pressure for natural gas as 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 adjustingthe pressure by the appropriate factor (ratio). For example, a 2 MPa (20 bar) working pressure system will requirepressures to be multiplied by 1,25.
