                    valves (see 5.5)

The minimum fitness for purpose requirements for check valves to connect to, or be used in water supply pipe systems, above or below ground (see EN 805), carrying water intended for human consumption is specified in this standard. The performance and design requirements and the conformity assessment method for check valves, whatever their materials and type, along with the requirements applicable to check valves up to DN 2 000 and PFA 6 bar to PFA 25 bar are covered. Applicable in priority to any other product or test standard: the requirements from other standards apply only when this standard refers to them.
