IS 15715 : 2024 Road Vehicles - Compressed Natural Gas (CNG)/Bio-Compressed Natural Gas (Bio-CNG)/Liquefied Petroleum Gas (LPG) - Fuel System Components - CNG/Bio-CNG/LPG Conduit (Ventilation Hose/Pipe)
1 SCOPE
1.1 This standard specifies definitions, test methods and requirements of conduit (ventilation hose /pipe), of CNG/bio-CNG/LPG onboard fuel system components, intended for use on motor vehicles defined in IS 14272.
1.1.1 This standard is applicable to CNG/bio-CNG/ LPG fuel system components intended to be used on vehicles using compressed natural gas/biocompressed natural gas/liquefied petroleum gas in accordance with IS 15320 (Part 1) (mono-fuel or bi-fuel or dual fuel applications as applicable).
1.1.2 This standard 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; and
d) CNG/bio-CNG/LPG fuel systems components for the propulsion of marine craft.
e) Hydrogen natural gas blend (HCNG) fuel system components
1.1.3 This standard is based upon a service pressure for compressed natural gas/bio-compressed natural gas as a fuel at 20 MPa (200 bar) and liquefied petroleum gas as a fuel at 2 MPa (20 bar) settled at 15 °C.
