Produits en acier pour récipients à pression ne figurant pas dans l'ISO 2604, Parties 1 à 6 — Dérivation des propriétés de rupture sous contrainte prolongée

Defines a procedure for obtaining and for assessing the data necessary to establish long-time stress rupture values for steels for pressure purposes for steels where properties different from those internationally agreed are being claimed. The purpose of a standard procedure is to minimize any differences in long-time estimates obtained in different countries due to differences in the quantity and duration of the data used and differences in the method of analysing the data.
