ISO 12614-4:2014 PDF

Scope: This part of ISO 12614 specifies tests and requirements for the manual valve, a liquefied natural gas fuel system component intended for use on the types of motor vehicles defined in ISO 3833.This part: of 1 fuel containers; 2)j stationary gas enginesS; 3)] container mounting hardware; 4)] electronic fuel management; 5] refueling receptacles. NOTE1 Lis recognized that miscellaneous components not Specifically covered herein can be examined to meet the criteria ofthis part of ISO 12614 and tested according to the appropriate functional tests， NOTE 2 All references to pressure in this bart of I9012614 are to be considered gauge pressures unless otherwise specified， NOTE3 This part of ISO 012614 is based upon a working pressure for natural gas as a fuel of 16 MPa (16 bam)， (Lbar=01MPa=105Pai1MPa=1L1N/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 reduire pressures to be multiplied by 1,25，
