GB/T 6165—2008计数法与国际现行标准化测试方法的实验比较
Experimental comparison of the particle counting method in China’s national standard GB/T 6165—2008 with some foreign standards
摘要：
以过滤元件最易透过粒径（MPPS）效率为评价基准，进行了比较评估。介绍了参考过滤器的主要性能参数及测试过程主要参数。评估结果表明，新版国家标准中的计数法与现行美国标准接近，相比于现行的欧洲及日本标准，更接近于MPPS基准效率,可满足国际市场的要求。

Abstract：
Performs the experimental comparison evaluation with the evaluation base of MPPS efficiency for filtration units. Presents the key performance factors of reference filters and key testing factors. As a result, the particle counting method regulated in the national standard approaches that in American standard, and its result is closer to that given by the reference MPPS tests than the current EU and JIS standards, and the national standard could meet the requirements of the international market.
