What is this standard about?
It covers calibrating, verifying and validating welding equipment after installation as part of workshop or site maintenance operations.
Who is this standard for?
- Inspection companies in a number of sectors, including oil and gas, marine, general engineering and construction
- Authorised training and qualification bodies responsible for ensuring that training and examinations are in accordance with this standard
- Test houses
- Contractors who provide welding services on site
Why should you use this standard?
It specifies requirements for calibration, verification and validation of welding equipment used for controlling:
- Process variables during fabrication
- The properties of welding equipment or equipment used for allied processes where the resulting output can’t be documented readily or economically by subsequent monitoring, inspection and testing. This involves process variables influencing the fitness-for-purpose and in particular the safety of the fabricated product.
In addition, Annex B gives guidance on requirements for calibration, verification and validation as part of acceptance testing of equipment used for welding or allied processes, and Annex C provides information for when other parties are involved in calibration, verification and validation activities.
NOTE 1: This standard is based on the lists of process variable stated in international standards for specification of welding procedures, in particular, but not exclusively, in the ISO 15609- series.
NOTE 2: Requirements to calibrate, verify and validate as part of inspection, testing, non-destructive testing or measuring of final welded products to confirm product compliance are outside the scope of this standard. It is limited to calibration, verification and validation of equipment after installation as part of workshop and site operations for maintenance and or operation. Nor does it have anything to do with the manufacture and installation of equipment for welding. Requirements for new equipment are found in directives and product codes (standards) as necessary.
What’s changed since the last update?
The standard was systematically reviewed by technical experts to ensure its continued market relevance. This standard is a technical revision of the 2005 version which has been withdrawn.
