LPG equipment and accessories - Inspection and testing of LPG road tankers

This document specifies minimum requirements for the inspection and testing of the LPG road tanker, which
includes its tank, tank accessories and vehicle LPG equipment.
This document does not specify requirements for the initial inspection (after manufacture) of a tank, see
EN 12493 or the road tanker, see EN 12252.
NOTE 1 There is no upper size limit for the tank as this will be determined by the gross vehicle weight limitation.
NOTE 2 For inspection and testing requirements of equipment other than the tank, tank accessories and vehicle LPG
equipment, see applicable regulations.

Dieses Dokument legt Mindestanforderungen an die Inspektion und Prüfung von Straßentankwagen für
Flüssiggas (LPG), einschließlich der Tanks, dem Tankzubehör und der Flüssiggas-Fahrzeugausrüstung
(LPG) fest.
Dieses Dokument enthält keine Anforderungen an die erstmalige Prüfung (nach der Herstellung) des Tanks,
siehe EN 12493 oder des Straßentankwagens, siehe EN 12252.
ANMERKUNG 1 Es besteht keine obere Begrenzung für die Größe der Tanks, da diese durch die Bruttomasse des
Fahrzeugs begrenzt wird.
ANMERKUNG 2 Für die Inspektions- und Prüfanforderungen von anderen Ausrüstungsteilen als Tanks und Flüssiggas-
Ausrüstung, siehe die jeweiligen internationalen/nationalen Bestimmungen.
