BS EN ISO 17662:2016 specifies requirements for calibration, verification and validation of
equipment used forcontrol of process variables during fabrication, andcontrol 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 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.Cross References:ISO 669ISO 5171ISO 5172:2006ISO 5826ISO 3834-1ISO 3834-2ISO 3834-3ISO 3834-4ISO 4063ISO 8206ISO 9000ISO 10012ISO 14744-1ISO 14744-2ISO 14744-3ISO 14744-4ISO 14744-5ISO 14744-6ISO/TR 16060ISO/TR 18491IEC 62135-1IEC 62135-2EN 50505EN 60974-1ISO 6947ISO 14554-1ISO 14554-2ISO 14555ISO 15609-1ISO 15609-2ISO 15609-3ISO 15609-4ISO 15609-5ISO 15614-11ISO 15616-1ISO 15616-2ISO 15616-3ISO 15616-4ISO 15620ISO 17637ISO 22827-1ISO 22827-2EN 13134EN 50504ISO 9001ISO 9004ISO/IEC Guide 99:2007All current amendments available at time of purchase are included with the purchase of this document.
