Annex A (normative) Mechanical testing of dampers and
                      valves
Annex B (informative) Thermal transmittance through
                      dampers and valves
Annex C (normative) Classification of a damper or
                      valve leakage

Gives methods for the rating and testing of dampers and valves used in air distribution systems with pressure differences up to 2 000 Pa. The test included are: a) leakage past a closed damper or valve (for classification see annex C); b) casing leakage (for classification see annex C); c) flow rate/pressure requirement characteristics; d) torque: (see annex A); e) thermal transmittance: (see annex B). Acoustic testing of dampers and valves is not included. Tests specified above apply to the following: a) measurement of leakage past a closed damper or valve; b) measurement of casing leakage; c) determination of flow rate and pressure requirements; d) measurement of torque characteristics; e) measurement of thermal transfer characteristics to determine insulation properties.
