Description / Abstract:
This International Standard specifies requirements for
calibration, verification and validation of equipment used for
— control of process variables during fabrication, and
— 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 1 This International Standard 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 as regards
requirements for calibration; verification and validation as part
of acceptance testing of equipment used for welding or allied
processes.
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 confirm product
compliance are outside the scope of the present International
Standard.
The subject of this International Standard is limited to
calibration, verification and validation of equipment after
installation, as part of the workshops’ and site operations for
maintenance and/or operation.
It needs to be stressed that this International Standard has
nothing to do with manufacture and installation of equipment for
welding. Requirements to 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.
