1 Scope
This International Standard specifies requirements for rubber hoses (including twin hoses) for welding, cutting and allied processes.
This International Standard 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 International Standard 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 International Standard applies neither to thermoplastics hoses nor to hoses used
for high pressure [>0,15 MPa (>1,5 bar)] acetylene.
