High-efficiency filters and filter media for removing particles in air - Part 5: Test method for filter elements (ISO 29463-5:2022)
高效过滤器和用于去除空气中的颗粒的过滤介质 - 第5部分:过滤元件的测试方法
This document specifies the test methods for determining the efficiency of filters at their most penetrating particle size (MPPS). It also gives guidelines for the testing and classification for filters with an MPPS of less than 0,1 μm (Annex B) and filters using media with (charged) synthetic fibres (Annex C). It is intended for use in conjunction with ISO 29463‑1, ISO 29463‑2, ISO 29463‑3 and ISO 29463‑4.
