GB/T 6165—2008计数法的性能评估测试
Performance evaluation test of particle counting method in the national standard GB/T 6165-2008
摘要：
通过实验评估了计数法的重复性等性能指标。测试结果表明，该方法可满足过滤行业日常检测需要。比较分析了单计数器顺序采样测试与双计数器同时采样测试，认为后者更适合于过滤行业。

Abstract：
Evaluates the performance parameters such as repeatability of the particle counting method by experiment. As a result, the method satisfies the routine test requirements of the filtration industry. Compares and analyses the sequential sampling by a single sampler and simultaneous sampling by two samplers, and considers that the latter is more suitable to be used in the filtration industry.
