What is BS EN 14420-5 - TW tank truck couplings about?  
BS EN 14420-5 specifies the fitting combinations, design, materials and dimensions for hose fittings with couplings for tank trucks (TW couplings).
Couplings for tank trucks in accordance with this document are intended to link hoses with connections for the transport of liquids, solid matters and gases with the exception of liquid gas and steam. They can be employed in a working pressure range of –0,8 bar1) up to 16 bar at working temperatures of –20 °C up to +65 °C. Couplings for tank trucks for other operating conditions are subject to agreement.
