EVS-EN ISO 15613:2025

ISO 15613 specifies how a preliminary welding procedure specification is qualified based on a pre-production welding test. ISO 15613 applies to arc welding, gas welding, beam welding, resistance welding, stud welding and friction welding of metallic materials.

One of the methods for welding procedure qualification is based on a pre-production welding test as given in ISO 15607. Qualification based on a pre-production welding test can be used where the shape and dimensions of the standard test pieces do not adequately represent the joint to be welded.

In such cases, one or more special test pieces can be made to simulate the production joint in all essential features, for example dimensions, restraint, heat sink effects and limited access. ISO 15613 is one of a number of standards dealing with specification and qualification of welding procedures.

ISO 15613:2025 text has been approved in Europe as EN ISO 15613:2025 without any changes.
