(Main)LPG equipment and accessories - Welded steel tanks for liquefied petroleum gas (LPG) - Road tankers design and manufacture
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 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.
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 Straßentankfahrzeuge und deren angeschweißte Zusatzeinrichtungen fest, die aus Kohlenstoffstahl, Kohlenstoff-Manganstahl und mikro-legiertem 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 Tankcontainer. ANMERKUNG 1 Im Zusammenhang dieser Norm ist der Begriff "Straßentankfahrzeug" mit der Bedeutung zu verstehen als "fest verbundener Tank" und "Aufsetztank" gemäß der Definition in ADR. ANMERKUNG 2 Die Ausrüstung der Behälter sowie die regelmäßige Überprüfung nach dem Zusammenbau ist sowohl durch EN 12252 sowie EN 14334 abgedeckt. ANMERKUNG 3 Das Baumuster des Straßentankfahrzeugs ist Inhalt einer Zulassung durch die zuständige Behörde, wie durch ADR vorgeschrieben.
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 européenne ne couvre pas les réservoirs destinés à des conteneurs de type ISO.
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.
NOTE 1 Dans le cadre de cette norme le terme « camion citerne » signifie « réservoirs fixes » et « réservoirs démontables » comme définis dans l’ADR.
NOTE 2 L’équipement des camions citernes et leurs contrôles et essais après construction sont couverts par les Normes EN 12252 et EN 14334 respectivement.
NOTE 3 Le mode de conception du camion citerne est sujet à l’approbation de l’autorité compétente comme prévu dans l’ADR.
Oprema in pribor za utekočinjeni naftni plin (UNP) - Varjene jeklene posode za utekočinjeni naftni plin (UNP) - Konstruiranje in izdelava cestnih cistern (vključno z dopolnilom A1)
Ta evropski standard določa minimalne zahteve za materiale, načrtovanje, konstrukcijo in postopke izvedbe ter preskuse za varjene posode za utekočinjen naftni plin (LPG) za cestne cisterne in njihove varjene priključke, izdelane iz ogljikovega, ogljikovega/manganovega in mikro legiranega jekla.
Zgornje omejitve velikosti ni, ker je ta določena z omejitvijo bruto teže vozila.
Ta evropski standard se ne uporablja za posode za cisterne.
OPOMBA 1 V tem standardu izraz »cestna cisterna« pomeni cisterne s pritrjeno posodo in cisterne s snemljivo posodo, kot so opredeljene v ADR.
OPOMBA 2 Za opremo cistern se uporablja EN 12252, za pregled in preskušanje po montaži pa se uporablja EN 14334.
OPOMBA 3 Tip izvedbe cestne cisterne mora odobriti pristojni organ, kot to zahteva ADR.

EN 12493:2008+A1:2012 (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. !Protection of the environment is a key political issue in Europe and elsewhere. Protection of the environment is taken in a very broad sense. What is meant is the total life cycle aspects of, e.g. a product on the environment, including expenditure of energy and during all phases from mining of raw materials, fabrication, packaging, distribution, use, scrapping, recycling of materials, etc. Annex M lists the clause where an environmental impact has been considered. It is recommended that manufacturers develop an environmental management policy. For guidance see ISO 14000 series." 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.
