42、n 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. This European Standard also specifies the requirements for the Electric Control Unit (ECU), which is not subjected to pressure
43、, and the gas-tight housing which has a working pressure below 20 kPa. This European Standard excludes containers. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate pla
44、ces in the text, and the publications are listed hereafter.
