标准范围
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.
