    Abstract - (Show below) - (Hide below)

    Describes requirements for rubber hoses (including twin hoses) for welding, cutting and allied processes. Also describes 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].
