Unfired pressure vessels - Part 2: Materials

This document specifies the requirements for steel products used for unfired pressure vessels.
For some metallic materials other than steel, such as spheroidal graphite cast iron, aluminium, nickel, copper, titanium, requirements are or will be formulated in separate parts of this document.
For metallic materials which are not covered by a harmonized material standard and are not likely to be in near future, specific rules are given in this part or the above cited parts of this document.

Unbefeuerte Druckbehälter - Teil 2: Werkstoffe

Diese Europäische Norm legt die Anforderungen an Stahlerzeugnisse für unbefeuerte Druckbehälter fest.
Für einige metallische Werkstoffe außer Stahl, z. B. Gusseisen mit Kugelgraphit, Aluminium, Nickel, Kupfer, Titan, sind oder werden die Anforderungen in weiteren Teilen dieser Europäischen Norm festgelegt.
Für metallische Werkstoffe, die nicht in harmonisierten Werkstoffnormen enthalten sind und es auch in naher Zukunft nicht sein werden, sind spezielle Regeln in diesem Teil oder in den oben genannten Teilen dieser Europäischen Norm enthalten.

Récipients sous pression non soumis à la flamme - Partie 2: Matériaux

Nekurjene tlačne posode - 2. del: Materiali

Ta dokument določa zahteve za jeklene izdelke, ki se uporabljajo za neogrevane tlačne posode. Za nekatere kovinske materiale, ki niso jeklo, npr. (siva) litina s kroglastim grafitom, aluminij, nikelj, baker, titan, so oziroma bodo zahteve oblikovane v ločenih delih tega dokumenta.
Za kovinske materiale, ki niso zajeti v ta harmonizirani standard za materiale in predvidoma tudi ne bodo v
