标准范围

ISO 16890-2:2016规定了用于测量一般通风空气过滤器的部分效率和气流阻力的气溶胶产生、试验设备和试验方法。它旨在与ISO 16890-1、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（24,0 in×24,0 in）的试验台。ISO 16890（所有零件）是指当按照ISO 16890（所有零件）中规定的程序进行测试时，ePM1效率小于或等于99%，ePM10效率大于20%的一般通风用颗粒空气过滤器元件。注:本试验程序的下限设定为20%的最低ePM10效率，因为低于该水平的试验滤芯很难满足本程序的统计有效性要求。通过其他适用的试验方法（见ISO 29463（所有部分））对该气溶胶部分之外的空气过滤器元件进行评估。便携式房间空气净化器中使用的滤芯不在本范围内。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。

ISO 16890-2:2016 specifies the aerosol production, the test equipment and the test methods used for measuring fractional efficiency and air flow resistance of air filters for general ventilation.It is intended for use in conjunction with ISO 16890？1, 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 (24,0 inch × 24,0 inch).ISO 16890 (all parts) 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 within ISO 16890 (all parts).NOTE The lower limit for this test procedure is set at a minimum ePM10 efficiency of 20 % since it will be very difficult for a test filter element below this level to meet the statistical validity requirements of this procedure.Air filter elements outside of this aerosol fraction are evaluated by other applicable test methods, (see ISO 29463 (all parts)).Filter elements used in portable room-air cleaners are excluded from the scope.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.
