IS 15716 : 2024 Road Vehicles - Compressed Natural Gas (CNG)/Bio-Compressed Natural Gas (Bio-CNG) - Fuel System Components - High Pressure Fuel Line (Rigid) with End Connections [Having Pressure Exceeding 2.15 MPa (21.5 bar)]
1 SCOPE
1.1 This standard specifies definitions, test methods and requirements of CNG/bio-CNG high pressure fuel line (rigid) with end connections having pressure exceeding 2.15 MPa (21.5 bar), of CNG/bio-CNG on board 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 or dual fuel applications).
1.1.2 This standard is not applicable to thefollowing:
a) Liquefied natural gas (LNG) fuel systemcomponents located upstream of andincluding the vaporizer;
b) Fuel containers;
c) Stationary gas engines;
d) CNG/bio-CNG fuel systems componentsfor the propulsion of marine craft; and
e) Hydrogen natural gas blend (HCNG) fuelsystem components.
