    BS EN ISO 3821:2019 Gas welding equipment. Rubber hoses for welding, cutting and allied processes
    Edition: 2021

Description of BS EN ISO 3821:2019 2021

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 −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 ISO 8207.

This document applies neither to thermoplastics hoses nor to hoses used for high pressure [>0,15 MPa (>1,5 bar)] acetylene.
