This document specifies main requirements, limits, inspection conditions and acceptance requirements as well as related inspection documents of welders for welded cast iron test pieces and workpieces.

It provides a set of technical rules for a systematic qualification test of a welder´s skills, and enables such qualifications to be uniformly accepted independently of the type of product, location and examiner or examining body.

This document specifies the testing of a welder´s skill unless a higher level skill test is required.

The acceptance of a welder´s skill in accordance with this document implies a practical experience and knowledge regarding the welding process, materials and safety requirements (see Annex C).

This document is to be used when requirements on part of a customer, testing or monitoring body or other organization are postulated.

This document defines the qualification test of welders for the fusion welding of cast irons. The welding processes referred to in this standard include those fusion welding processes which are designated as manual or partly mechanized welding. It does not cover fully mechanized and automated welding processes (see EN ISO 14732). Cast iron materials which are covered by this document are mentioned in 5.4.

The inspection document and certification are made out under the responsibility of the testing body.
