标准摘要
[中文适用范围]： 本文件建立了一种调节方法来确定最小分数测试效率。 它旨在与ISO 16890-1、ISO 16890-2和ISO 16890-3结合使用，并提供了测试装置和调节柜的相关测试要求以及应遵循的调节程序。 本文件中描述的调节方法是指标称表面积为 610 mm × 610 mm（24 英寸 × 24 英寸）的测试装置。 本文件涉及用于一般通风的颗粒空气过滤器滤芯，根据 ISO 16890 系列中定义的程序进行测试时，ePM1 效率小于或等于 99%，ePM10 效率大于 20%。 注：此测试程序的下限设置为最低 ePM10 效率 20%，因为低于此水平的测试过滤器元件很难满足此程序的统计有效性要求。 便携式室内空气净化器中使用的过滤元件不包括在本文件的范围内。 [外文原描述]： This document establishes a conditioning method to determine the minimum fractional test efficiency. It is intended to be used in conjunction with ISO 16890‑1, ISO 16890‑2 and ISO 16890‑3, and provides the related test requirements for the test device and conditioning cabinet as well as the conditioning procedure to follow. The conditioning method described in this document is referring to a test device with a nominal face area of 610 mm × 610 mm (24 inches × 24 inches). This document refers to particulate air filter elements for general ventilation having an e PM 1 efficiency less than or equal to 99 % and an e PM 10 efficiency greater than 20 % when tested according to the procedures defined within the ISO 16890 series. NOTE The lower limit for this test procedure is set at a minimum e PM 10 efficiency of 20 % since it will be very difficult for a test filter element below this level to meet the statistical validity requirements of this procedure. Filter elements used in portable room-air cleaners are excluded from the scope of this document.
