本文件规定了用于测量一般通风空气过滤器的部分效率和气流阻力的气溶胶生产、测试设备和测试方法。 它旨在与ISO 16890-1、ISO 168903和ISO 16890m4结合使用。 本文件中所述的试验方法适用于0.25 m3/s（900 m3/h，530 ft3/min）和1.5 m3/s之间的空气流量（5400m3/h，3178 ft3/in），指的是标称表面面积为610 mm×610 mm（24.0 in×24.0 inch）的试验台。 本文件是指当按照ISO 16890系列中规定的程序进行测试时，ePM1效率小于或等于99%，ePM10效率大于20%的一般通风用颗粒空气滤清器滤芯。 注:本试验程序的下限设定为最低ePM10效率20%，因为低于该水平的试验滤芯很难满足试验的统计有效性要求 本文件不适用于便携式房间空气滤清器中使用的滤芯。

This document specifies the aerosol production, the test equipment and the test methods used for measuring fractional efficiency and air flow resistance of air filters for general ventilation. It is intended to be used in conjunction with ISO 16890‑1, ISO 16890‑3 and ISO 16890‑4. The test method described in this document is applicable for air flow rates between 0,25 m3/s (900 m3/h, 530 ft3/min) and 1,5 m3/s (5 400 m3/h, 3 178 ft3/min), referring to a test rig with a nominal face area of 610 mm × 610 mm (24.0 inches × 24.0 inches). This document refers to particulate air filter elements for general ventilation having an ePM1 efficiency less than or equal to 99 % and an ePM10 efficiency greater than 20 % when tested as per the procedures defined within the ISO 16890 series. NOTE      The lower limit for this test procedure is set at a minimum ePM10 efficiency of 20 % since it is very difficult for a test filter element below this level to meet the statistical validity requirements of this procedure. This document is not applicable to filter elements used in portable room-air cleaners.
