试解读《一般通风用空气过滤器》国际新标准

Analysing the New ISO Standard of Air Filter for General Ventilation

介绍近年颁发的国际标准ISO 16890:2016 《一般通风用空气过滤器》的主要内容,该系列标准详尽规定了一般通风用空气过滤器,对空气悬浮颗粒物的质量过滤效率(ePMx)的测试装置、试验方法、数据处理和性能分级。该标准是应对当前大气环境质量广泛欠佳,急需采取措施改善室内空气质量的现状应运而生的。该标准睿智地避开了一些技术难点、创建了一些新概念和新思路,既尽可能沿用国际现行一般通风用空气过滤器相关标准的试验系统和方法,同时又获得了实用和可信的ePMx结果,是一项值得推广的新标准。对国内如何应对该标准,提出了一些想法和建议。

The recently published ISO 16890：2016＂Air filter for general ventilation＂, in which the test facilities ＆ methods, data analysis and performance classification of particulate matter efficiency （ePMx） to air filter for general ventilation are specified in detail, is introduced in this paper. The standard is arising in response to the situation of the even severe global air pollution and the urgent requiring of indoor air quality improvement. In the standard, some techniques and difficulties are wisely avoided, and some new concepts and possibilities are created. Practical and reliable ePMx are obtained, as well as current test system and methods in relative standards of air filters for general ventilation are followed as much as possible. It is worth promotion and some suggestions are proposed to the domestic application of the standard.
