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 pressure vessel, accessories and vehicle LPG equipment.
This document does not apply to compartmented road tankers.
NOTE 1   There is no upper size limit for the pressure vessel as this will be determined by the gross vehicle weight limitation.
NOTE 2   For further information on inspection and testing requirements of equipment other than the pressure vessel, accessories and vehicle LPG equipment, see applicable regulations.

Flüssiggas-Geräte und Ausrüstungsteile - Inspektion und Prüfung von Straßentankwagen für Flüssiggas (LPG)

Dieses Dokument legt Mindestanforderungen an die Inspektion und Prüfung von Straßentankwagen für Flüssiggas (LPG), einschließlich des Druckbehälters, der Ausrüstungsteile und der Flüssiggas-Fahrzeugausrüstung fest.
Dieses Dokument gilt nicht für Straßentankwagen, die in mehrere Abschnitte unterteilt sind.
ANMERKUNG 1   Es besteht keine obere Begrenzung für die Größe der Druckbehälter, da diese durch die maximale Bruttomasse des Fahrzeugs begrenzt wird.
ANMERKUNG 2   Für weitere Informationen zu den Inspektions- und Prüfanforderungen von anderer Ausrüstung als Druckbehälter, Ausrüstungsteile und Flüssiggas-Fahrzeugausrüstung siehe die jeweiligen anwendbaren Rechtsvorschriften.

Équipements pour GPL et leurs accessoires - Inspection et essais des véhicules citernes routiers pour GPL

Le présent document spécifie les exigences minimales relatives à l'inspection et aux essais des véhicules citernes routiers pour GPL qui incluent les réservoirs sous pression, leurs accessoires et les équipements pour véhicules GPL.
Le présent document ne s'applique pas aux véhicules-citernes routiers compartimentés.
NOTE 1   Il n'y a pas de limite supérieure de taille pour le réservoir sous pression dans la mesure où elle est déterminée par la limitation de masse brute du véhicule.
NOTE 2   Pour des informations supplémentaires concernant les exigences d'inspection et d'essais des équipements autres que le réservoir sous pression, ses accessoires et les équipements pour véhicules GPL, voir les réglementations en vigueur.

Oprema in pribor za utekočinjeni naftni plin (UNP) - Pregledi in preskušanje cestnih cistern za UNP

Ta dokument določa minimalne zahteve za preglede in preskušanje cestnih cistern za utekočinjeni naftni plin (LPG), kar zajema njihove tlačne posode, pribor in opremo za vozilo za LPG.
Ta dokument ne določa zahtev za začetni pregled (po izdelavi) tlačne posode, glej standard EN 12493, ali za obratovalno opremo cestne cisterne, glej standard EN 12252.
Ta dokument se ne uporablja za cestne cisterne z več predelki.
OPOMBA 1:   Zgornje omejitve velikosti tlačne posode ni, ker je ta določena z omejitvijo bruto teže vozila.
OPOMBA 2:   Za zahteve glede pregledov in preskušanja opreme, ki ni tlačna posoda, pribor in oprema za vozilo za utekočinjen naftni plin, glej veljavne predpise.

It is recommended that companies using this document develop an environmental management policy.
For guidance, see EN ISO 14001 [3].
It has been assumed in the drafting of this document that the execution of its provisions is entrusted to
appropriately qualified and experienced people.
All pressures are gauge pressures unless otherwise stated.
NOTE This document requires measurement of material properties, dimensions and pressures. All such
measurements are subject to a degree of uncertainty due to tolerance
