Annex A (normative) Test method for the airflow
                    characteristics of valves with an
                    air release function (see 5.3 and
                    5.3.1)
Annex B (normative) Test method for the airflow
                    characteristics of valves with an
                    air intake function (see 5.3 and
                    5.3.2)
Annex C (normative) Test method for the endurance of
                    valves with air intake and/or air
                    release functions (see 5.3 and 5.3.3)

Gives the minimum fitness for purpose requirements for valves to be used in, or connected to, water supply pipe systems above or below ground (see EN 805), carrying water meant for human consumption. It covers the design requirements, performance requirements, and the conformity assessment method for valves, whatever their type and materials.
