The work of
22、 preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental
23、, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO
24、/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives). Attention is drawn to the possibili
25、ty that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of pat

31、onitoring, 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 p
32、rocedures, 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; verifica
33、tion 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
34、 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
35、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 v

48、and test equipment are used for many purposes and as part of many work operations during welding fabrication. However, the purposes can be grouped as follows:1) demonstration of conformance of product to specified requirements;2) control of processes where the resulting output cannot be readily or e
49、conomically verified by subsequent monitoring, inspection and testing;3) general process control.Measuring, inspection and test equipment used for demonstration of conformance of product to specified requirements (1) should be properly calibrated, verified, or validated. This is, for example, required in ISO 9001. Many of the procedures used for demonstration of conformance inspection are covered by standards, which typically include provisions for calibration, verification, or validation. This is, for example, the case fo
