This Technical Report 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 Technical Report covers grouping systems for the following standardized materials:
aluminium and its alloys;
copper and its alloys;
In case of dispute, for example where variations in properties such as thickness and yield strength occur, ISO/TR 15608 applies.
