This standard BS EN 17931:2026 Gas welding equipment. Manual gas equipment for welding, heating and cutting. Periodic inspection is classified in these ICS categories:

• 25.160.30 Welding equipment

This document specifies guidelines for periodic inspections of gas equipment for welding, cutting and allied processes placed downstream of the gas cylinder’s valve as shown in Figure 1 or, in the case of centralized distribution, downstream from the tapping point, since commissioning. NOTE In some cases, gas cylinders can be replaced by cylinder bundles. Acetylene cylinder bundle systems upstream of the tapping point are excluded. This document applies to gas welding equipment intended for professional use which utilizes compressed gases up to 300 bar (30 MPa), acetylene, liquefied petroleum gas (LPG), methylacetylene-propadiene mixtures (MPS) and carbon dioxide (CO2) and related mixtures. This document does not apply to automatic applications of gas welding, cutting and allied processes.
