適用范圍：This International Standard specifies methods for the aerodynamic testing and rating of assemblies suitable for use with air distribution systems operating at high or low velocity and high or low pressure.The tests included in this International Standard cover :a) leakage past a closed inlet valve or control valve;b) casing leakage;c) characteristics of the constant or variable flow r?te con-troller;d) degree of temperature mixing achieved by a dual duct box;e) flow r?te characteristics for single duct units.These tests are designed to determine the performance of the assemblies and the results will enable the comparison of suitability of such assemblies when correctly installed in a high or low velocity/pressure air distribution system.
