Air filters for general ventilation — Part 3: Determination of the gravimetric efficiency and the air flow resistance versus the mass of test dust captured 一般通风用空气过滤器第3部分:重量效率和气流阻力与捕获的试验粉尘质量的测定

发布日期： 2024-08-22

本文件规定了用于测量一般通风用空气过滤器的重量效率和气流阻力的测试设备和测试方法。
它旨在与ISO 16890-1、ISO 16890-2和ISO 16890-4结合使用。
本文件中描述的测试方法适用于0.25 m3/s（900 m3/h，530 ft3/min）和1.5 m3/s（5 400 m3/h，3 178 ft3/min）之间的空气流速，参考标称表面积为610 mm × 610 mm（24 in × 24 in）的试验台。
本文件涉及用于一般通风的微粒空气过滤器元件，当按照ISO 16890系列中定义的程序进行测试时，其ePM1效率小于或等于99%，ePM10效率大于20%。
注:该测试方法的下限设定为最低ePM10效率20%，因为低于该水平的测试滤芯很难满足该方法的统计有效性要求。本文件不适用于便携式室内空气净化器中使用的过滤元件。

This document specifies the test equipment and the test methods used for measuring the gravimetric efficiency and resistance to air flow of air filter for general ventilation.
It is intended for use in conjunction with ISO 16890-1, ISO 16890-2 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 in × 24 in).
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 in 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 does not apply to filter elements used in portable room-air cleaners.
