Gas welding equipment — Pressure gauges used in welding, cutting and allied processes

This document specifies requirements for Bourdon-tube pressure gauges normally used with compressed gas systems at pressures up to 30 MPa (300 bar) in welding, cutting and allied processes. It also covers use for dissolved acetylene and for liquefied gases under pressure. It does not cover gauges for acetylene in acetylene-manufacturing plants.

Matériels de soudage au gaz — Manomètres utilisés pour le soudage, le coupage et les techniques connexes

Le présent document spécifie des exigences pour des manomètres à tube de Bourdon utilisés habituellement en soudage, coupage et techniques connexes, pour les installations de gaz comprimés jusqu'à des pressions de 30 MPa (300 bar). Il traite également de l'acétylène dissous et des gaz liquéfiés sous pression. Il ne traite pas des manomètres pour acétylène utilisés dans les usines de production d'acétylène.

Gas welding equipment — Air-aspirated hand blowpipes — Specifications and tests

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.

Gas tightness of equipment for gas welding and allied processes

This document specifies the maximum external gas leakage rates which are acceptable for equipment used for welding, cutting and allied processes and provides the procedures of measurement. It applies to individual components which are used in the gas supply to a blowpipe from the connecting point of the hose (outlet of the cylinder valve or connecting point to a gas supply plant). It does not apply to gas supply plant. NOTE Specific requirements on the test method and conditions/procedure for measurement of the maximum external leakages can be given in individual standards, e.g. ISO 9012 for air-aspirated hand blowpipes. Concerning the method and the conditions to be applied, the individual standard takes precedence over this document. The maximum external leakages according to this document apply.

Gas welding equipment — Rubber hoses for welding, cutting and allied processes

This document specifies requirements for rubber hoses (including twin hoses) for welding, cutting and allied processes. This document specifies requirements for rubber hoses for normal duty of 2 MPa (20 bar) and light duty [limited to hoses for maximum working pressure of 1 MPa (10 bar) and with bore up to and including 6,3 mm]. This document applies to hoses operated at temperatures −20 °C to +60 °C and used in: — gas welding and cutting; — arc welding under the protection of an inert or active gas; — processes allied to welding and cutting, in particular, heating, brazing, and metallization. This document does not specify requirements for hose assemblies; these are detailed in ISO 8207. This document applies neither to thermoplastics hoses nor to hoses used for high pressure [>0,15 MPa (>1,5 bar)] acetylene.

Gas welding equipment — Acetylene manifold systems for welding, cutting and allied processes — General requirements

ISO 14114:2017 applies to acetylene cylinder manifold systems extending from the cylinder valve or the bundle outlet connections to the outlet connection of the main shut-off valve. It specifies requirements for design, materials and testing of cylinder manifold systems for the supply of acetylene for use in welding, cutting and allied processes. ISO 14114:2017 applies to acetylene cylinder manifold systems in which acetylene single cylinders or acetylene bundles are coupled for collective gas withdrawal. NOTE National regulations exist regarding limitation of the amount of single cylinders/bundles of acetylene on a single location (e.g. in warehouse or connected to a manifold system). ISO 14114:2017 also covers a test procedure for decomposition blockers.
