AS/NZS 1335:2020

This Standard adopts ISO 3821:2019, which 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 the following:(a) Gas welding and cutting.(b) Arc welding under the protection of an inert or active gas.(c) Processes allied to welding and cutting, in particular, heating, brazing, and metallization.This document does not specify requirements for hose assemblies.This document applies neither to thermoplastics hoses nor to hoses used for high pressure [>0.15 MPa (>1.5 bar)] acetylene.
