Resumen

This document specifies tests and requirements for the flexible fuel lines, a liquefied natural gas fuel system component intended for use on the types of motor vehicles defined in ISO 3833. This document 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 is recognized that miscellaneous components not specifically covered herein can be examined to meet the criteria of this document and tested according to the appropriate functional tests.

NOTE 2        All references to pressure in this document are considered gauge pressures unless otherwise specified.

NOTE 3        This document 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 MPa (20 bar) working pressure system will require pressures to be multiplied by 1,25.
