Gas welding equipment - Rubber hoses for welding, cutting and allied processes (ISO 3821:2019)

Status: Valid

Scope
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.
