Who is this standard for? It’s for the fabrication and manufacturing industries, especially those with critical safety requirements such as structural engineering, oil and gas, energy, nuclear, chemical plant, shipbuilding, and pressure vessels and equipment. Why should you use this standard? As well as establishing a European grouping system for materials for welding, this content can also be applied for other purposes such as heat treatment, forming and non-destructive testing. It covers grouping systems for the following standardized materials:

Steel Aluminium and its alloys Copper and its alloys Cast irons

In case of dispute, for example where variations in properties such as thickness and yield strength occur, ISO/TR 15608 applies. What’s changed since the last update? This is a technical revision of the 2006 edition of this document.
