DESCRIPTION

BS EN ISO 3821:2019


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 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.
