本欧洲标准规定了压力差高达2 000 Pa的空气分配系统中使用的阻尼器和阀门的测试和额定值的方法。 本欧洲标准中纳入的测试是: a）通过封闭的阻尼器或阀门的泄漏（分类见附件C）; b）套管泄漏（分类见附件C）; c）流量/压力要求特性; d）扭矩:（见附件A）; e）热透过率:（见附件B）。 本欧洲标准中不包括阻尼器和阀门的声学测试。 上述测试适用于以下内容: f）通过闭合的阻尼器或阀门测量泄漏; g）套管泄漏测量; h）确定流量和压力要求; i）扭矩特性测量（见附件A）; j）测量热传递特性以确定绝缘性能（见附件B）。 注意阻尼器或阀门的动态性能的某些方面取决于它们连接的空气分配系统，因此难以隔离测量。这些考虑导致了欧洲标准的动态性能测量的这些方面的遗漏。此外，与其他空气分配部件一样，还有

This European Standard specifies methods for the testing and rating of dampers and valves used in air distribution systems with pressure differences up to 2 000 Pa. The tests incorporated in this European Standard 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). The acoustic testing of dampers and valves is not included in this European Standard. The tests specified above apply to the following: f) measurement of leakage past a closed damper or valve; g) measurement of casing leakage; h) determination of flow rate and pressure requirements; i) measurement of torque characteristics (see Annex A); j) measurement of thermal transfer characteristics to determine insulation properties (see Annex B). NOTE Certain aspects of the dynamic performance of dampers or valves are dependent upon the air distribution system to which they are connected and are, therefore, difficult to measure in isolation. Such considerations have led to the omission of these aspects of the dynamic performance measurements from this European Standard. Also, in common with other air distribution components, the results from tests carried out in accordance with this European Standard may not be directly applicable if the damper or valve is situated in an area of non-uniform flow.
