描述了一种新的分级过滤效率实验室测试方法，该方法适用于用于一般通风的空气滤清器。该方法涵盖0.3至10微米的粒径范围，使用人工生成的试验气溶胶和光学粒子计数器测量试验空气滤清器上游和下游的气溶胶浓度。在使用三个空气滤清器进行的一系列演示测试中，对于所有颗粒尺寸，分数效率可重复到两个百分点以内。关键词:1995年，气溶胶，空气过滤器，颗粒物，通风，实验室测试，空气净化，效率引用:ASHRAE Trans。1995年，第101卷，第一部分，论文编号3842，97-110，5个图，5个标签，参考文献

Describes a new fractional filtration efficiency laboratory test method developed for air cleaners used in general ventilation. The method covers the particle diameter size range from 0.3 to 10 micrometers, using an artificially-generated test aerosol and an optical particle counter to measure aerosol concentrations upstream and downstream of the test air cleaner. In a series of demonstration tests with three air cleaners, the fractional efficiency was repeatable to within two percentage points for all particle sizes.KEYWORDS: year 1995, Aerosols, air filters, particles, ventilation, laboratory testing, air cleaning, efficiency
