ISO 12614-1:2014 PDF

Scope: This part of ISO 12614 specifies general requirements and definitions of liquefied natural gas fuel system components, intended for use on the types of motor vehicles as defined in ISO 3833. It also provides general design principles and specifies requirements for instructions and marking. This part of ISO 12614 is not applicable to the following: a) fuel containers; c) container mounting hardware; e) fuelling receptacles. b) stationary gas engines; d) 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 fuel of 1,6 MPa [16 bar1)]. 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.
