全面通风用空气过滤器. 第1部分: 基于颗粒物效率(ePM)的技术规格, 要求和分类体系

[中文适用范围]： 本部分ISO 16890建立了一种基于颗粒物（PM）的通用通风空气过滤器的效率分类系统。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配合使用。本部分中描述的测试方法适用于0.25 m³/s（900 m³/h，530 ft³/min）至1.5 m³/s（5400 m³/h，3178 ft³/min）之间的空气流速，参考的测试台额定面积为610 mm × 610 mm（24英寸×24英寸）。ISO 16890（所有部分）指的是根据ISO 16890-1、ISO 16890-2、ISO 16890-3和ISO 16890-4中定义的程序进行测试，其ePM1效率小于或等于99%的通用通风用颗粒空气过滤器元件。具有更高初始效率的空气过滤器元件由其他适用的测试方法进行评估（见ISO 29463-1、ISO 29463-2、ISO 29463-3、ISO 29463-4和ISO 29463-5）。用于便携式室内空气净化器的过滤元件不包括在本部分ISO 16890的范围内。根据ISO 16890（所有部分）获得的结果本身不能定量地用于预测服务中的效率和寿命。影响性能的其他因素在附录A中描述。 [外文原描述]： 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.
