This part of ISO 3822 gives detailed descriptions for mounting and operating draw-off taps and mixing valves in such laboratory tests. These taps and mixing valves are for use with cold and/or hot water in buildings (for sinks, wash-basins, baths, etc.) or next to buildings (for example for garden use). Draw-off taps and mixing valves are the most common kind of appliance used in water supply installations. ili ted without license from IHS Not for Resale
