ISO 15500-1-2015 pdf free.Road vehicles – Compressed natural gas (CNG) fuel system components— Part 1: General requirements and definitions.
This Ihirt ot ISO 15500 speci lies getwral requirements and definitions of compressed natu rat gas fuel system coflipoflents, 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 15500 is applicable to vehicles (mono—fuel, hi—fuel, or dual—fuel applications) using natural gas En accordance with ISO 15403-1. It is not applicable to the following:
a) liquefied natural gas (LNG) luel system components located upstream ot and including, the vaporizer;
h) fuel containers;
c) stationary gas engines;
ci) container mounting hardware;
e) electronic fuel management;
1) refuelling receptacles.
NOTE 1 It is recognized that miscellaneous components not specifically covered herein can he examined to meet the criteria of this part of ISO 15500 and tested according to the appropriate functional tests.
NOTE 2 All relerences to pressure in this part of ISO ISSO() are to he considered gauge unless otherwise specified.
NOTE 3 This part of ISO 15500 is based upon a service pressure for natural gas as fuel of 20 MPa 1200 bar1)j settled at 15 °C. Other service pressures can he accomnlo(lateci by adjusting the iiresstire by the appropriate factor (ratio). For example, a 25 MPa (250 bar) service pressure system will require pressures to be multiplied by 1.25,
