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) [with nominal size up to and including 50].
This document specifies requirements for rubber hoses for light duty [limited to hoses for maximum working pressure of 1 MPa (10 bar) and with nominal size up to and including 6,3].
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 specifies the maximum working pressure for acetylene as 0,15 MPa (1.5 bar).
This document specifies the maximum working pressure for hydrogen and helium as 1 MPa (10 bar)
This document does not specify requirements for hose assemblies; these are detailed in ISO 8207.
This document applies neither to thermoplastic hoses nor to hoses used for high pressure [>0,15 MPa (>1,5 bar)] acetylene.
