This standard BS EN ISO 3821:2019 Gas welding equipment. Rubber hoses for welding, cutting and allied processes is classified in these ICS categories:
- 25.160.30 Welding equipment
- 83.140.40 Hoses
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 2Â MPa (20Â bar) and light duty [limited to hoses for maximum working pressure of 1Â MPa (10Â bar) and with bore up to and including 6,3Â mm].
This document applies to hoses operated at temperatures −2 0 °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 ISOÂ 8207.
This document applies neither to thermoplastics hoses nor to hoses used for high pressure [>0,15Â MPa (>1,5Â bar)] acetylene.
