BS EN 14420-8:2004+A1:2007 Hose fittings with clamp units. Symmetrical half coupling (Guillemin system)
BS EN 14420-8 applies to hose fittings with symmetrical half couplings (Guillemin system), with mobile locking ring, for those assemblies with a maximum working pressure of up to 16 bar, with hose tails according to BS EN 14420-2 and clamp units according to BS EN 14420-3. Couplings in accordance with this document serve as link between hoses and connections to transport liquids, solids (e.g. powders, granules) except steam and liquid gas. It specifies dimensions, types of connections, quality of materials, marking requirements and testing requirements. The working temperature range is − 20 °C up to + 65 °C.
