RUBBER HOSES AND HOSE ASSEMBLIES FOR LIQUEFIED PETROLEUM GAS IN MOTOR VEHICLES - SPECIFICATION (ISO 8789:1994, IDT)
This Malaysian Standard specifies the requirements for rubber hoses and hose assemblies, up to a maximum bore of 20 mm, for use in motor vehicles with liquefied petroleum gas (LPG) installations. The hoses are designed for use up to a maximum pressure 2,5 MPa (25 bar) and a working temperature between - 40 °C and + 80 °C.
NOTE 1: If hoses are used at temperatures higher than 80 “C, i.e. in an engine compartment and/or as connecting hoses with exhaust-pins (used by air-cooled engines for the evaporation of the gas) it will have to be shown that these hoses can withstand the higher temperatures.
