Bibliography

Defines the general design and testing requirements for all components, in automotive Liquefied Petroleum Gas (LPG) propulsion systems, which have a working pressure equal to or greater than 20 kPa. It also specifies the requirements for the Electric Control Unit (ECU), which is not subjected to pressure, and the gas-tight housing, which has a working pressure below 20 kPa.
