LPG equipment and accessories - Welded steel tanks for liquefied petroleum gas (LPG) - Road tankers design and manufacture
This European Standard specifies minimum requirements for materials, design, construction and workmanship procedures, and tests for welded LPG road tanker tanks and their welded attachments manufactured from carbon, carbon/manganese and micro alloy steels.
There is no upper size limit as this is determined by the gross vehicle weight limitation.
This European Standard does not cover tanks for ISO type containers.
FlüssiggasGeräte und Ausrüstungsteile - Geschweißte Druckbehälter aus Stahl für Flüssiggas (LPG) - Konstruktion und Herstellung von Straßentankfahrzeugen
Diese Europäische Norm legt Mindestanforderungen an Werkstoffe, Konstruktion, Ausführung und Herstel¬lungsverfahren sowie Prüfungen für geschweißte Druckbehälter für Flüssiggas für Straßentank¬fahrzeuge und deren angeschweißte Zusatzeinrichtungen fest, die aus Kohlenstoffstahl, Kohlenstoff Mangan¬stahl und mikrolegiertem Stahl hergestellt sind.
Es besteht keine Obergrenze für die Größe, da diese durch die Begrenzung der Bruttomasse des Fahrzeugs bestimmt wird.
Diese Europäische Norm gilt nicht für Behälter für ISO Container.
Équipements pour GPL et leurs accessoires - Réservoirs en acier soudés pour gaz de pétrole liquéfié (GPL) - Conception et construction des camions-citernes
La présente Norme européenne spécifie les exigences minimales relatives aux matériaux, à la conception, à la construction et à la qualité d’exécution, ainsi que les essais des réservoirs soudés de camions-citernes utilisés pour le transport du GPL et de leurs accessoires soudés fabriqués en acier au carbone, en acier au carbone/manganèse et en acier micro-allié.
La présente norme ne définit pas de taille limite supérieure pour le réservoir étant donné que celle-ci sera déterminée par la limite du poids total en charge du véhicule.
La présente Norme européenne ne couvre pas les réservoirs destinés à des conteneurs de type ISO.

EN 12493:2008 (E) 5 Foreword This document (EN 12493:2008) has been prepared by Technical Committee CEN/TC 286 “Liquefied petroleum gas equipment and accessories”, the secretariat of which is held by NSAI. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by September 2008, and conflicting national standards shall be withdrawn at the latest by September 2008. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 12493:2001. This European Standard has been submitted for reference into the technical annexes of the European Agreement concerning the international carriage of dangerous goods by road (ADR). The standards listed in the normative references and covering the basic requirements of the ADR not addressed within the present standard are normative only if the standards themselves are referred to in the technical annexes of ADR. Main changes from 2001 version: update of reference standards, particularly relating to qualification of welding, in text and Clause 2; restriction to maximum UTS added to 4.2 and Annex A to align with ADR restrictions; revision of symbols and presentation of D.3.2.5 to align with EN 13445 (source standard). No technical changes to end design result; editorial changes. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom.

EN 12493:2008 (E) 6 Introduction This European Standard calls for the use of substances and procedures that may be injurious to health if adequate precautions are not taken. It refers only to technical suitability and does not absolve the user from legal obligations relating to health and safety at any stage. It has been assumed in the drafting of this European Standard that execution of its provisions is entrusted to appropriately qualified and experienced people. 1 Scope This European Standard specifies minimum requirements for materials, design, construction and workmanship procedures, and tests for welded LPG road tanker tanks and their welded attachments manufactured from carbon, carbon/manganese and micro alloy steels. There is no upper size limit as this is determined by the gross vehicle weight limitation. This European Standard does not cover tanks for tank containers. NOTE 1 In the context of this standard the term "road tanker" is understood to mean “fixed tanks” and “demountable tanks” as defined in ADR. NOTE 2 The equipment of the tanks and the inspection and testing after assembly is covered by EN 12252, and EN 14334, respectively. NOTE 3 The design type of the road tanker is subject to the approval by the competent authority, as required by ADR.
