Welding - Grouping systems for materials - European materials (ISO/TR 20172:2021)

This document establishes a European grouping system for materials for welding purposes, classified in accordance with the grouping system of ISO/TR 15608.
It is also applicable for other purposes such as heat treatment, forming and non-destructive testing.
This document covers grouping systems for the following standardized materials:
a) steel;
b) aluminium and its alloys;
c) copper and its alloys;
d) cast irons;
e) nickel and nickel alloys.
For materials that are not assigned to a group in this document, the criteria of ISO/TR 15608 apply.
