ČSN EN ISO 17931 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.
