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.

This document specifies the general requirements and tests for decomposition blockers downstream of pressure regulators in acetylene manifold systems (see ISO 14114). Decomposition blockers can be used in the low-pressure section (downstream of acetylene manifold system outlet) up to 0,15 MPa (1,5 bar) e.g. in pipelines, outlet points or for the protection of low-pressure sections in big pipe systems. Decomposition blockers can only be used in sections with pure acetylene. The possible backflow of oxygen or air into the section where the decomposition blocker is installed needs to be prevented by a non-return valve downstream of the decomposition blocker.

This document specifies requirements and test methods for air-aspirated hand blowpipes.
This document applies to blowpipes for brazing, soldering, heating, fusion and other allied thermal
processes which use a fuel gas and aspirated air (injector-type blowpipes) and are intended for manual
use.
This document is applicable to:
— air-aspirated hand blowpipes which are fed with a fuel gas in the gaseous phase, at a controlled
pressure by a regulator, through a gas supply hose;
— air-aspirated hand blowpipes which are fed with a liquefied fuel gas in the gaseous phase at the
container pressure, through a gas supply hose;
— so-called liquid-phase blowpipes which are fed with a fuel gas in the liquid phase, and where thermal
evaporation takes place within the blowpipe.
It does not apply to blowpipes in which the fuel gas leaves the injector in the liquid phase, or to so-called
“cartridge” blowpipes where the gas supply is fixed directly onto the blowpipe and possibly constitutes
the shank.
NOTE Figures 1 to 4 are given for guidance only, to facilitate the explanation of the terms. They do not
specify the construction details, which are left to the discretion of the manufacturer.

This part of IEC 60974 specifies safety and performance requirements for industrial and professional equipment used in arc welding and allied processes to feed filler wire. This document is applicable to WIRE FEEDERS and to WIRE-FEED CONTROLS that are stand-alone (separate from the welding equipment), housed together in a single enclosure or housed in a single enclosure with other welding equipment. The WIRE FEEDER can be suitable for manually or mechanically guided torches. This document is not applicable to spool-on torches, which are covered by IEC 60974-7. NOTE 1 Typical allied processes are electric arc cutting and arc spraying. NOTE 2 This document does not include electromagnetic compatibility (EMC) requirements, which are given in IEC 60974-10.

IEC 60974-10:2014 specifies a) applicable standards and test methods for radio-frequency (RF) emissions; b) applicable standards and test methods for harmonic current emission, voltage fluctuations and flicker; c) immunity requirements and test methods for continuous and transient, conducted and radiated disturbances including electrostatic discharges. This standard is applicable to equipment for arc welding and allied processes, including power sources and ancillary equipment, for example wire feeders, liquid cooling systems and arc striking and stabilizing devices. This third edition cancels and replaces the second edition published in 2007 and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - inclusion of optional use of a decoupling network and a load outside the test chamber; - inclusion of an alternative test setup for portable equipment; - inclusion of test conditions for complex controls, liquid cooling systems and arc striking and stabilizing devices; - update of the applicable limits related to the updated reference to CISPR 11; - exclusion of the use of narrow band relaxations for RF emission limits; - update of the applicable limits for harmonics and flicker and inclusion of flow-charts related to the updated reference to IEC 61000-3-11 and IEC 61000-3-12; - update of the requirements for voltage dips related to the updated reference to IEC 61000-4-11 and IEC 61000-4-34; - update of the informative annex for installation and use; - inclusion of symbols to indicate the RF equipment class and restrictions for use.

IEC 60974-8:2021 specifies safety and performance requirements for gas consoles intended to be used with combustible gases or oxygen. These gas consoles are designed to supply gases for use in arc welding, plasma cutting, gouging and allied processes in non-explosive atmospheres. The gas console can be external or internal to the power source enclosure. In the latter case, the power source shall meet the requirements of both IEC 60974-1 and this document. This third edition cancels and replaces the second edition, published in 2009. This edition constitutes a technical revision. The significant technical changes with respect to the previous edition are the following:
- changes induced by the publication of IEC 60974-1:2017;
- requirements for the rating plate as in IEC 60974-1:2017, Clause 15;
- requirements for the instructions in 13.2.
This part of IEC 60974 is to be used in conjunction with IEC 60974-1.
