ICS Code (Welding equipment): 25.160.30
ICS Code (Hoses): 83.140.40
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 standard 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
