Tanks for transport of dangerous goods - Testing, inspection and marking of metallic tanks

This European Standard specifies testing, inspection and marking for the type approval, initial inspection, periodic inspection, intermediate inspection and exceptional check of metallic tanks (shell and equipment) of fixed tanks (tank vehicles), demountable tanks, rail tank wagons, portable tanks and tank containers for the transport of dangerous goods.
This European Standard is not applicable to battery-vehicles and battery-wagons comprising cylinders, tubes, pressure drums, bundles of cylinders and multiple element gas containers (MEGCs), independent of whether the elements are receptacles or tanks.
It is essential that the requirements of the applicable regulations for the transport of dangerous goods prevail in all cases over those of this standard.

Tanks für die Beförderung gefährlicher Güter - Prüfung, Inspektion und Kennzeichnung von Metalltanks

Diese Europäische Norm legt die Prüfung, Inspektion und Kennzeichnung für die Baumusterprüfung, erstmalige Prüfung, wiederkehrende Prüfung, Zwischenprüfung und außerordentliche Prüfung von Metalltanks (Tankkörper und Ausrüstung) von fest verbundenen Tanks (Tankfahrzeugen), Aufsetztanks, Eisenbahnkesselwagen, ortsbeweglichen Tanks und Tankcontainern für die Beförderung gefährlicher Güter fest.
Diese Europäische Norm gilt nicht für
-   Batterie-Fahrzeuge und Batterie-Wagen, bestehend aus Flaschen,
-   Großflaschen, Druckfässer, Flaschenbündel, und
-   Gascontainer mit mehreren Elementen (MEGCs),
unabhängig davon, ob die Elemente Gefäße oder Tanks sind.
Es ist von grundlegender Bedeutung, dass die Anforderungen der geltenden Vorschriften für die Beförderung gefährlicher Güter immer Vorrang vor den Anforderungen der vorliegenden Norm haben.

Citernes destinées au transport de matières dangereuses - Épreuve, contrôle et marquage des citernes métalliques

La présente Norme européenne spécifie les épreuves, les contrôles et le marquage pour l’agrément de type, le contrôle initial, le contrôle périodique, le contrôle intermédiaire et le contrôle exceptionnel des citernes métalliques (réservoirs et équipements) des citernes fixes (véhicules-citernes), citernes démontables/amovibles, wagons-citernes, citernes mobiles et conteneurs-citernes destinés au transport de matières dangereuses.
La présente Norme européenne n’est pas applicable aux véhicules-batteries et wagons-batteries composés de bouteilles, tubes, fûts à pression, cadres de bouteilles et aux conteneurs à gaz à éléments multiples (CGEM), qu’il s’agisse de récipients ou de citernes.
Il est essentiel que les prescriptions des réglementations applicables concernant le transport des marchandises dangereuses prévalent dans tous les cas sur celles de la présente norme.

Cisterne za prevoz nevarnega blaga - Preskušanje, pregled in označevanje kovinskih cistern

Ta evropski standard določa preskušanje, pregledovanje in označevanje za tipsko odobritev, začetne, redne in vmesne preglede ter izredne preglede kovinskih cistern (posoda cisterne in oprema), pritrjenih cistern (cestna cisterna), odstranljivih cistern, železniških vagonov s cisterno, premičnih cistern in cistern-zabojnikov za prevoz nevarnega blaga.
Ta evropski standard se ne uporablja za akumulatorska vozila in akumulatorske vagone, ki vključujejo valje, cevi, tlačne valje, sklope jeklenk in plinske vsebnike iz več elementov (MEGC), ne glede na to, ali so elementi posode ali cisterne.
Bistveno je, da zahteve ustreznih predpisov za prevoz nevarnega blaga v vseh primerih prevladajo nad zahtevami tega standarda.
