Over deze norm
Defines the minimum fitness for purpose requirements for valves to be used in, or connected to, water supply pipe systems above or below ground (including the meter valves), and also suitable for pipe systems carrying raw or treated water (e.g. for irrigation, for fire figting). Specifies the general design requirements, the performance requirements and the conformity assessment method for valves, whatever their type and materials. Applies in priority to any product or test standard: the requirements from other standards apply only when this standard refers to them. Deals with the requirements which are common to several types of valves; it is applicable only when quoted as reference in one of the other parts of this standard.
