ÖNORM EN ISO 15614-12

This part of ISO 15614 specifies the tests which can be used for qualification of welding procedure specifications for spot, seam, and projection welding processes. This International Standard is part of the ISO 15614 series. Details of this series are given in ISO 15607, Annex A. This part of ISO 15614 defines the conditions for carrying out tests and the limits of validity of a qualified welding procedure for all practical welding operations covered by this part of ISO 15614. The tests required to qualify the procedure for a particular component/assembly depend on the performance and quality requirements of the component/assembly and shall be established before any qualification is undertaken. Tests shall be carried out in accordance with this part of ISO 15614 unless more severe tests are specified by the relevant application standard or contract when these shall apply. The acceptability of applying the principles of this part of ISO 15614 to other resistance welding processes should be established before any qualification is undertaken.
