IS 15713 : 2024 Road Vehicles - Compressed Natural Gas (CNG)/Bio-Compressed Natural Gas (Bio-CNG) - Fuel System Components - Pressure Regulator
1 SCOPE
1.1 This standard specifies definitions, test methods and requirements of pressure regulator of CNG/bio-CNG onboard fuel system components intended for use on motor vehicles defined in IS 14272.
1.1.1 This standard is applicable to CNG/bio-CNGfuel system components intended to use on vehicles using compressed natural gas/bio-compressed natural gas in accordance with IS 15320 (Part 1) (mono-fuel or bi-fuel applications or dual fuel applications).
1.1.2 This standard is not applicable to the following:
a) Liquefied natural gas (LNG) fuel systemcomponents located upstream of, andincluding, the vaporizer;
b) Fuel containers;
c) Stationary gas engines;
d) Container mounting hardware;
e) Electronic fuel management;
f) Refuelling receptacles;
g) CNG/bio-CNG fuel systems componentsfor the propulsion of marine craft; and
h) Hydrogen natural gas blend (HCNG) fuelsystem components.
1.1.3 This standard is based upon a service pressurefor compressed natural gas/bio-compressed natural gas as a fuel at 20 MPa (200 bar) settled at 15 °C. Other service pressures could 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. All references to pressure are to be considered gauge pressures unless otherwise specified.
