ISO 16890-1:2016建立了基于颗粒物（PM）的一般通风空气过滤器效率分类系统。它还概述了测试程序，并规定了评估和标记过滤器以及记录测试结果的一般要求。它旨在与ISO 16890？2、ISO 16890？3和ISO 16890？4一起使用。 ISO 16890本部分所述的试验方法适用于0.25 m3/s（900 m3/h，530 ft3/min）和1.5 m3/s（5400 m3/h，3178 ft3/min）之间的空气流量，指的是标称表面面积为610 mm×610 mm（24 in×24 in）的试验台。 ISO 16890（所有零件）是指当按照ISO 16890-1、ISO 16890-2、ISO 16890-3和ISO 16890-4中规定的程序进行测试时，ePM1效率小于或等于99%的一般通风用颗粒空气过滤器元件。初始效率较高的空气滤清器滤芯可通过其他适用的试验方法进行评估（见ISO 29463）- 1、ISO 29463-2、ISO 29463-3、ISO 29463-4和ISO 29463-5）。 便携式房间空气净化器中使用的滤芯不在ISO 16890本部分的范围内。 根据ISO 16890（所有零件）获得的性能结果本身不能定量地用于预测在使用中的效率和寿命性能。附件A中描述了影响性能的其他因素。

ISO 16890-1:2016 establishes an efficiency classification system of air filters for general ventilation based upon particulate matter (PM). It also provides an overview of the test procedures, and specifies general requirements for assessing and marking the filters, as well as for documenting the test results. It is intended for use in conjunction with ISO 16890？2, ISO 16890？3 and ISO 16890？4.

The test method described in this part of ISO 16890 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 inch × 24 inch).

ISO 16890 (all parts) refers to particulate air filter elements for general ventilation having an ePM1 efficiency less than or equal to 99 % when tested according to the procedures defined within ISO 16890？1, ISO 16890？2, ISO 16890？3 and ISO 16890？4. Air filter elements with a higher initial efficiency are evaluated by other applicable test methods (see ISO 29463-1, ISO 29463-2, ISO 29463-3, ISO 29463-4 and ISO 29463-5).

Filter elements used in portable room-air cleaners are excluded from the scope of this part of ISO 16890.

The performance results obtained in accordance with ISO 16890 (all parts) cannot by themselves be quantitatively applied to predict performance in service with regard to efficiency and lifetime. Other factors influencing performance to be taken into account are described in Annex A.
