LPG equipment and accessories - Automotive liquefied petroleum gas components - Other than containers

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

Flüssiggas-Geräte und Ausrüstungsteile - Bauteile für Autogasanlagen/Treibgasanlagen - Bauteile, ausgenommen Autogastanks

Dieses Dokument legt die allgemeinen Auslegungs- und Prüfanforderungen an alle Bauteile in Autogas (LPG)-Antriebsanlagen (en: Liquefied Petroleum Gas) mit einem maximal zulässigen Druck von gleich oder größer 20 kPa fest.
Dieses Dokument legt auch die Anforderungen an das elektronische Steuergerät (ECU, en: electronic control unit), das nicht druckbeaufschlagt ist, sowie an den gasdichten Armaturenkasten fest, der einen maximal zulässigen Druck von weniger als 20 kPa hat.
Dieses Dokument gilt nicht für Autogastanks.
