摘要
通过比对国内外标准，分析了高效粒子空气（HEPA）过滤器过滤效率测试方法的演变，提出了采用多分散相DOP介质，对过滤器进行针对不同粒径的过滤效率试验的方法．并按照此方法搭建了试验台架。经对被测过滤器的试验验证，该计径计数法比标准ASMEAG-1中的试验方法更可靠，被测过滤器的过滤效率优于ASME AG-1的要求。
Based on the comparison of domestic and international codes, this paper analyzes the de- velopment of filter performance test methods, and puts forward a method using polydiperse aerosol for filter efficiency test under different particle sizes. According to this method, the test platform is built. The filter efficiency test showed that the particle size and counting method is more reliable than the method in ASME AG-1, and the performance of filters tested is better than the requirements of ASME AG-1.
