LPG equipment and accessories - Equipping of LPG road tankers

This document specifies equipment and accessories for road tankers used for the transport of Liquefied Petroleum Gas (LPG) and identifies the equipment that is considered necessary to ensure that filling, transportation and discharge operations can be carried out safely. It specifies the requirements for the assembly of the accessories and the vehicle LPG equipment to the road tanker. This document also identifies additional equipment and accessories that can be used on road tankers carrying LPG.
This document does not preclude the use of alternative designs, materials and equipment testing which provide the same or a higher level of safety. ADR [9] requires that such alternative technical codes be recognized by the competent authority, provided that the minimum requirements of section 6.8.2 of ADR [9] are complied with.
This document does not apply to “tank-containers” or “battery-vehicles” used for the transport of LPG.

Flüssiggas-Geräte und Ausrüstungsteile - Ausrüstung von Straßentankwagen für Flüssiggas (LPG)

Dieses Dokument legt die Ausrüstung und Ausrüstungsteile von Straßentankwagen fest, die für die Beförderung von Flüssiggas (LPG) eingesetzt werden, und kennzeichnet die Ausrüstung, die als notwendig betrachtet wird, um sicherzustellen, dass Füll , Beförderungs  und Entleerungsvorgänge sicher durchgeführt werden können. Es legt die Anforderungen an die Montage der Ausrüstungsteile und der Flüssiggas Fahrzeugausrüstung an den Straßentankwagen fest. Dieses Dokument legt auch zusätzliche Ausrüstung und Ausrüstungsteile fest, die auf mit LPG beladenen Straßentankwagen verwendet werden können.
Dieses Dokument schließt die Verwendung alternativer Auslegungen, Werkstoffe und Ausrüstungen nicht aus, sofern diese das gleiche oder ein höheres Sicherheitsniveau aufweisen. Das ADR [9] fordert, dass ein solches alternatives technisches Regelwerk durch die zuständige Behörde anerkannt werden muss, vorausgesetzt, die in Abschnitt 6.8.2 des ADR [9] angegebenen Mindestanforderungen werden erfüllt.
Dieses Dokument gilt nicht für zur Beförderung von LPG verwendete „Tankcontainer“ oder „Batteriefahrzeuge“.

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

Le présent document spécifie les équipements et accessoires pour véhicules-citernes routiers destinés au transport de gaz de pétrole liquéfié (GPL) et identifie les équipements jugés nécessaires pour que les opérations de remplissage, de transport et de déchargement puissent être effectuées en toute sécurité. Il spécifie les exigences relatives à l'assemblage des accessoires et des équipements pour véhicule GPL sur le véhicule-citerne routier. Le présent document identifie également les équipements et accessoires supplémentaires qui peuvent être utilisés sur des véhicules-citernes routiers destinés au transport de GPL.
Le présent document n'exclut pas l'utilisation de conceptions, matériaux et essais d'équipements qui garantissent au moins le même niveau de sécurité. L'ADR [9] exige que de tels codes techniques soient reconnus par l'autorité compétente à condition que les exigences minimales du paragraphe 6.8.2 de l'ADR [9] soient satisfaites.
Le présent document ne s'applique pas aux « conteneurs-citernes » ni aux « véhicules-batteries » utilisés pour le transport de GPL.
Voir l'EN 12493 pour la conception des véhicules-citernes routiers et l'EN 14334 [11] pour les exigences de contrôle et d'essai des véhicules-citernes routiers.

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

Ta evropski standard določa opremo in pribor za cestne cisterne, ki se uporabljajo za prevoz utekočinjenega naftnega plina (UNP), ter identificira opremo, ki je obvezna za varno izvajanje operacij polnjenja, prevoza in praznjenja. Določa zahteve za pritrjevanje pribora in opreme za vozilo za utekočinjen naftni plin na cestno cisterno. Ta evropski standard določa tudi dodatno opremo in pribor, ki se lahko uporablja na cestnih cisternah za prevoz utekočinjenega naftnega plina.
Ta evropski standard ne izključuje uporabe alternativnih preskušanj zasnove, materialov in opreme, ki zagotavljajo enako ali večjo raven varnosti. ADR [9] zahteva, da takšne alternativne tehnične kode priznava pristojni organ, in sicer v skladu z minimalnimi zahtevami razdelka ADR 6.8.2 [9].
Ta evropski standard se ne uporablja za »cisterne zabojnike« ali »baterijska vozila«, ki se uporabljajo za prevoz utekočinjenega naftnega plina.
