This European Standard specifies the design, materials, dimensions and marking requirements for cam locking couplings that serve as the link between hoses and connections to transport liquids, solids and gases, except liquid gas and steam. The couplings are capable of operating the pressure range −0,8 bar¹⁾ to 16 bar working pressure (for aluminium-cast-materials −0,8 bar to 10 bar) in a working temperature range of −20 °C up to +65 °C.
