    Defines the design, materials and dimensions of fittings for clamp type coupling assemblies for use with nominal sizes DN 15 to DN 50 steam and hot water hoses.

    Scope - (Show below) - (Hide below)

    This European Standard specifies the design, materials and dimensions of fittings for clamp type coupling assemblies for use with nominal sizes DN15 to DN50 steam and hot water hoses. It covers assemblies up to a maximum working pressure of 18bar1) (corresponding to a saturated steam temperature of 210°C).
