本文件规定了用于测量用于一般通风的空气过滤器的效率分数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？16890？3和ISO？16890？4. 本文件中描述的测试方法适用于空气流量在0.25？立方米/秒（900？立方米/小时，530？立方英尺/分钟）和1.5？m3/s（5？400？m3/h，3？178？ft3/min），指标称面面积为610？嗯？×？610？毫米（24.0英寸× 24.0英寸）。 本文件涉及ePM1效率小于或等于99的一般通风用微粒空气过滤器元件？%和大于20的ePM10效率？%当按照ISO中定义的程序进行测试时？16890系列。 笔记？该测试程序的下限设定为最低ePM10效率20？%，因为低于该水平的测试滤芯很难满足该p的统计有效性要求程序。 本文件不适用于便携式室内空气净化器中使用的滤芯。

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.
