Gas welding equipment – Rubber hoses for welding, cutting and allied processes (First revision) (ISO 3821:2008, IDT)
ICS: 25.160.30;
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.
