This European Standard specifies requirements for rubber hoses, including twin hoses and fluxed fuel gas hoses for welding, cutting and allied processes. The term "allied processes" means, in particular, heating, brazing and metallization. This standard specifies requirements for rubber hoses for normal duty up to 2 MPa (20 bar) and light duty [limited to hoses for maximum operating pressure up to 1 MPa (10 bar) and with nominal bore less than or equal to 6,3 mm]. This standard pertains to hoses operated at temperatures - 20 °C to + 60 °C.
