关于一般通风用空气过滤器国际标准ISO 16890：2016的探讨
Discussion on ISO 16890:2016 Air filters for general ventilation
摘要：
ISO 16890：2016《一般通风用空气过滤器》系列标准是首个测试并报告空气过滤器对大气悬浮颗粒物的质量过滤效率(ePMx)及分级的国际标准。结合ISO 16890：2016标准的主要创新或关键点，系统介绍了该标准的基本思路，并阐述了笔者对该标准的一些认识和观点。就当前国内行业配合该标准的实施宜做的准备提出了建议。

Abstract：
The ISO 16890:2016 series standard of Air filters for general ventilation is the first international standard which tests, reports and classifies the particulate matter efficiency (ePMx) of air filters to ambient air suspended particulate. Combined with the main innovations or key points of ISO 16890:2016 standard, systematically presents the basic conception of the standard and expounds the authors understanding and opinions on the standard. Proposes some suggestions to the domestic industry for the implementation of the standard.
