Annex A (normative) Test method for the endurance of check
        valves

This European Standard defines the minimum fitness for purpose requirements for check valves to be used in, or connected to, water supply pipe systems, above orbelow ground (see prEN 805:1996), carrying water intended for human consumption.This standard specifies the design requirements, the performance requirements and the conformity assessment method for check valves, whatever their type and materials. This standard applies in priority to any product or test standard: the requirements from other standards apply only when this standard refers to them.
