This part of EN 13480 covers the requirements for materials (including clad materials) for industrial piping and supports covered by EN 13480-1 constructed of metallic materials and is currently limited to steels with sufficient ductility below the creep range. It specifies the assessment of compliance for these materials. It also provides rules for the establishment of technical delivery conditions for materials for industrial piping.
Metallische industrielle Rohrleitungen - Teil 2: Werkstoffe
Dieser Teil der EN 13480 legt die Anforderungen an Werkstoffe (einschließlich Plattierungswerkstoffe) für Rohrleitungen nach der EN 13480-1 aus metallischen Werkstoffen fest; sie ist zur Zeit auf Stähle ausreichender Duktilität begrenzt. Dieser Teil gilt nicht im Zeitstandbereich. Die Norm legt das für diese Werkstoffe anzuwendende Konformitätsbewertungsverfahren fest. Ferner enthält sie Regeln für die Festlegung von technischen Lieferbedingungen für Werkstoffe für Rohrleitungen.
