Equipment Safety Standards Welding Equipment Safety Standards address the proper design, manufacture, installation, and use of the varied and complicated equipment used for welding. Given the nature of welding, the obvious potential for danger requires safety considerations to be an integral part of the design process and manufacturing of the equipment involved. Welding equipment safety is therefore the first line of defense, and standardization helps assure cohesion between the equipment that welders use and everything surrounding it.

ISO 15615:2013

Gas welding equipment - Acetylene manifold systems for welding, cutting and allied processes - Safety requirements in high-pressure devices

ISO 15615:2013 establishes the general specifications, requirements and tests for devices located on the high-pressure side of acetylene manifold systems as defined in ISO 14114. It does not cover the high-pressure piping, flexible hoses and the regulator.

This standard is also available from: BS  /  ON  /  SS


IEC 62135-1 Ed. 2.0 b:2015

Resistance welding equipment - Part 1: Safety requirements for design, manufacture and installation

IEC 62135-1:2015 applies to equipment for resistance welding and allied processes and includes single and multiple welding stations which may be manually or automatically loaded and/or started. This second edition cancels and replaces the first edition published in 2008. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - creepage distances for pollution degree 4 are no longer valid (see Table 2); - insulation requirements for Class II equipment are defined (see Table 3); - dielectric test voltage interpolation restriction lower limit is changed to 220 V and interpolation for control and welding circuit is clarified (see Table 4); - maximum temperature for insulation systems are reviewed in accordance with current edition of IEC 60085 (see Table 7); - marking of terminals is defined (see 10.3); - table for nominal voltages of supply networks is changed adopting Table B.2 of IEC 60664-1:2007 in place of the Table B.1 values referenced in the previous edition to provide for equipment to be connected to both earthed and unearthed systems. The change impacts the creepage and clearance distance requirements for some supply voltage ratings (see Annex A); - touch current in fault condition are measurement procedures are clarified (see 6.4.4 and Annex C); - welding circuit touch current is defined (see 6.2.6); - touch current in normal condition are clarified and moved in protection against electric shock in normal service (see 6.3.7); - heating test conditions are clarified (see 7.1.1); - external surface temperature rise limitation is changed (see 7.3.2).


IEC 62135-2 Ed. 2.0 b:2015

Resistance welding equipment - Part 2: Electromagnetic compatibility (EMC) requirements

IEC 62135-2:2015 is applicable to equipment for resistance welding and allied processes which are connected to mains supplies with rated voltages up to 1 000 V a.c. r.m.s. This standard does not define safety requirements. This second edition cancels and replaces the first edition published in 2007 and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - 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 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; - inclusion of symbols to indicate the RF equipment class and restrictions for use; - inclusion of EM field immunity test for frequency from 1,4 GHz to 2,7 GHz; - inclusion of emission limits for class B resistance welding equipment magnetic fields between 150 kHz and 30 MHz.


BS EN 730-1:2002

Gas welding equipment. Safety devices. Incorporating a flame (flashback) arrestor (British Standard)

This part of EN 730 specifies the general requirements and tests for safety devices for fuel gases and oxygen or compressed air incorporating a flame (flashback) arrestor used downstream of manifold, cylinder and (or) pipeline outlet regulators, and upstream of blowpipes for welding, cutting and allied processes. This Standard does not specify the location of these devices in the gas system. This Standard does not include requirements for safety devices which do not incorporate a flame arrestor which are covered by prEN 730-2.

This standard is also available from: DIN  /  ON  /  SS


BS EN 730-2:2002

Gas welding equipment. Safety devices. Not incorporating a flame (flashback) arrestor (British Standard)

This part of EN 730 specifies the general requirements and tests for safety devices for fuel gases and oxygen or compressed air which do not incorporate a flame (flashback) arrestor used downstream of manifold, cylinder and (or) pipeline outlet regulators, and upstream of blowpipes for welding, cutting and allied processes. This standard does not specify the location of these devices in the gas system. This standard does not include requirements for safety devices which incorporate a flame arrestor which are covered by prEN 730-1.

This standard is also available from: DIN  /  ON  /  SS


DIN 8541-2:1987

Hoses for welding, cutting and allied processes; hoses with protective cover for use with fuel gas, oxygen and other non-combustible gases (FOREIGN STANDARD)

For the use in welding, cutting and allied processes, particularly for thermal cutting, hoses with coating for fuel gas, oxygen and other non combustible gases are specified. For the hoses the dimensions, safety requirements, tests and details for marking are laid down.


DIN 8541-3:1995

Rubber oxygen hoses for welding, cutting and allied processes, with or without protective cover, designed for special requirements - Part 3: Safety requirements and testing (FOREIGN STANDARD)

The document applies to oxygen rubber hoses with and without coatings for special requirements on equipments and machines for welding, cutting and allied processes. It does not apply for rubber hoses on converters.


ISO 5175:1987

Equipment used in gas welding, cutting and allied processes - Safety devices for fuel gases and oxygen or compressed air - General specifications, requirements and tests

Refers to safety devices used downstream of cylinder or pipeline outlet regulators and of pipeline outlet valves, and upstream of blowpipes. Does not specify location and combination of these devices in the gas system. Cancels and replaces the first edition of ISO 5175-1 published in 1983.
