ISO 15500-6-2001 道路车辆—压缩天然气 CNG燃料系统部件—自动阀
适用范围： This part of ISO 15500 specifies tests and requirements
for the automatic valve, a compressed natural gas fuel system
component intended for use on the types of motor vehicles defined in
ISO 3833.
This part of ISO 15500 is applicable to vehicles using natural gas
in accordance with ISO 15403 mono-fuel, bi-fuel or dual-fuel
applications. It is not applicable to the following:
a liquefied natural gas LNG fuel system components located
upstream of, and including, the vaporizer
b fuel containers
c stationary gas engines
d container mounting hardware
e electronic fuel management
f refuelling receptacles.
NOTE 1 It is recognized that miscellaneous components not
specifically covered herein can be examined to meet the criteria of
this part of ISO 15500 and tested according to the appropriate
functional tests.
NOTE 2 All references to pressure in this part of ISO 15500 are to
be considered gauge pressures unless otherwise specified.
NOTE 3 This part of ISO 15500 is based upon a service pressure for
natural gas as a fuel of 20 MPa [200 bar] settled at 15 ℃. Other
service pressures can be accommodated by adjusting the pressure by
the appropriate factor ratio. For example, a 25 MPa 250 bar
service pressure system will require pressures to be multiplied by
1,25.
note: 1 1 bar 0,1 MPa 10 Pa 1 MPa 1 N/mm
