ÖNORM EN ISO 11970

Issue date: 2026 04 01

Specification and qualification of welding procedures for production welding of steel and nickel-base castings (ISO 11970:2025)

This document specifies how a welding procedure specification (WPS) for production welding of steel castings is qualified. Tests are intended to be carried out in accordance with this document, unless additional tests are specified by the purchaser or by agreement between the contracting parties. This document defines the conditions for the execution of welding procedure qualification tests and the limits of validity of a qualified welding procedure for all practical welding operations within the range of essential variables. This document applies to the arc welding of steel castings. The principles of this document can be applied to other fusion welding processes subject to agreement between the contracting parties.

Frequently Asked Questions about ÖNORM EN ISO 11970

What is a "Single-User Licence"?

When you purchase a standard from the Austrian Standards webshop (e.g. ÖNORM, ISO), a single-user licence is included as standard. This entitles a single person to use the standard. A multi-user licence is required if several employees need access. It enables company-wide, legally compliant use and sharing of standards.

How can I get involved in the further development of this standard?

Standardization thrives on expertise and participation. Anyone interested can play an active role in its further development – for example, by joining the relevant committee or a working group. In this way, you can help shape the content and contribute to advancing the state of the art.
