Welding - Calibration, verification and validation of equipment used for welding, including ancillary activities (ISO 17662:2025)

Scope

This document specifies requirements for calibration, verification and validation of equipment used for:
—     control of process variables during fabrication,
—     control of the properties of equipment used for welding or welding allied processes,
where the resulting output cannot be readily or economically documented by subsequent monitoring, inspection and testing. This involves process variables influencing the fitness-for-purpose and in particular the safety of the fabricated product.
NOTE            This document is based on the lists of process variables stated in International Standards for specification of welding procedures, in particular, but not exclusively in the ISO 15609 series. Future revisions of these International Standards can result in addition or deletion of parameters considered necessary to specify.
Some guidance is, in addition, given in Annex B for requirements for calibration, verification and validation as part of acceptance testing of equipment used for welding or allied processes.
This document does not specify requirements to calibrate, verify and validate as part of inspection, testing, non-destructive testing or measuring of final welded products performed in order to verify product conformance.
This document applies only to calibration, verification and validation of equipment for use in production or on site.
This document does not apply to the manufacture and installation of equipment for welding. Requirements for new equipment are formulated in directives and product codes (standards), as necessary.
Annex C provides information when other parties are involved in calibration, verification and validation activities.
