SIST EN 12806:2003

Automotive liquefied petroleum gas components - Other than containers

This European Standard specifies 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.
This European Standard 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.
This European Standard excludes containers.

Bauteile für Autogasanlagen/Treibgasanlagen - Bauteile, ausgenommen Autogastanks

Diese Norm gilt für die allgemeine Konstruktion und die Prüfanforderungen von allen Bauteilen in Motorfahrzeugen mit Flüssiggas als Antrieb, mit einem Betriebsdruck von gleich oder größer 20 kPa.
Diese Norm gilt auch für die Anforderungen an elektronische Steuergeräte (ECU), die nicht druckbeaufschlagt sind, und für die Anforderungen an gasdichte Armaturschutzkästen, die einem Betriebsdruck von weniger als 20 kPa ausgesetzt sind.
Diese Norm gilt nicht für Autogastanks.

Composants pour véhicules au gaz de pétrole liquéfiés - Composants autres que le réservoir

La présente Norme européenne spécifie la conception générale et les exigences relatives aux essais, pour tous les composants des véhicules a moteur utilisant, en tant que carburant, le gaz de pétrole liquéfié (GPL) dans leur systeme de propulsion, qui ont une pression de service égale ou supérieure a 20 kPa.
La présente Norme européenne spécifie également les exigences pour le module de contrôle électronique (ECU) qui n'est pas soumis a la pression, et le capot étanche qui a une pression de service inférieure a 20 kPa.
La présente Norme européenne exclut les réservoirs.
