Short description
The standard applies to drinking-water installations. Particularly fast-closing shut-off and tapping valves (magnetic valves, ball cocks, single-levermixer taps) can incur transient pressure surges in such systems, which can become apparent as annoying noise or even damage the system. The standard contains guidance on the avoidance and reduction of such pressure surges and noises. It addresses all persons involved in the planning, execution and upkeep of buildings. The standard does not apply to pressure booster, fire-exstinguishing, service water and wastewater installations.
