29、 extensively studied in the past decades. The results are that fine dust can be a serious health hazard, contributing to or even causing respiratory and cardiovascular diseases. Different classes of particulate matter can be defined according to the particle size range. The most important ones are P
30、M10, PM2,5and PM1. The U.S. Environmental Protection Agency (EPA), the World Health Organization (WHO) and the European Union define PM10as particulate matter which passes through a size-selective inlet with a 50 % efficiency cut-off at 10 m aerodynamic diameter. PM2,5and PM1are similarly defined. H
31、owever, this definition is not precise if there is no further characterization of the sampling method and the sampling inlet with a clearly defined separation curve. In Europe, the reference method for the sampling and measurement of PM10is described in EN 12341. The measurement principle is based o
32、n the collection on a filter of the PM10fraction of ambient particulate matter and the gravimetric mass determination (see EU Council Directive 1999/30/EC of 22 April 1999).As the precise definition of PM10, PM2,5and PM1is quite complex and not simple to measure, public authorities, like the U.S. EP
33、A or the German Federal Environmental Agency (Umweltbundesamt), increasingly use in their publications the more simple denotation of PM10as being the particle size fraction less or equal to 10 m. Since this deviation to the above mentioned complex “official” definition does not have a significant im
34、pact on a filter elements particle removal efficiency, the ISO 16890 series refers to this simplified definition of PM10, PM2,5and PM1.Particulate matter in the context of the ISO 16890 series describes a size fraction of the natural aerosol (liquid and solid particles) suspended in ambient air. The
35、 symbol ePMxdescribes the efficiency of an air cleaning device to particles with an optical diameter between 0,3 m and x m. The following particle size ranges are used in the ISO 16890 series for the listed efficiency values.Table 1 Optical particle diameter size ranges for the definition of the eff

In this application, air filters significantly influence the indoor air quality and, hence, the health
37、of people, by reducing the concentration of particulate matter. To enable design engineers and maintenance personnel to choose the correct filter types, there is an interest from international trade and manufacturing for a well-defined, common method of testing and classifying air filters according
38、to their particle efficiencies, especially with respect to the removal of particulate matter. Current regional standards are applying totally different testing and classification methods, which do not allow any comparison with each other, and thus hinder global trade with common products. Additional
39、ly, the current industry standards have known limitations by generating results which often are far away from filter performance in service, i.e. overstating the particle removal efficiency of many products. With this new ISO 16890 series, a completely new approach for a classification system is ado
40、pted, which gives better and more meaningful results compared to the existing standards.The ISO 16890 series describes the equipment, materials, technical specifications, requirements, qualifications and procedures to produce the laboratory performance data and efficiency classification based upon t
41、he measured fractional efficiency converted into a particulate matter efficiency (ePM) reporting system.Air filter elements according to the ISO 16890 series are evaluated in the laboratory by their ability to remove aerosol particulate expressed as the efficiency values ePM1, ePM2,5and ePM10.The ai
42、r filter elements can then be classified according to the procedures defined in ISO 16890-1. The particulate removal efficiency of the filter element is measured as a function of the particle size in the range of 0,3 m to 10 m of the unloaded and unconditioned filter element as per the procedures de
43、fined in ISO 16890-2. After the initial particulate removal efficiency testing, the air filter element is conditioned ISO 2016 All rights reserved vBS EN ISO 16890-4:2016ISO 16890-4:2016(E)according to the procedures defined in this part of ISO 16890 and the particulate removal efficiency is repeate
44、d on the conditioned filter element. This is done to provide information about the intensity of any electrostatic removal mechanism which may or may not be present with the filter element for test. The average efficiency of the filter is determined by calculating the mean between the initial efficie
45、ncy and the conditioned efficiency for each size range. The average efficiency is used to calculate the ePMxefficiencies by weighting these values to the standardized and normalized particle size distribution of the related ambient aerosol fraction. When comparing filters tested in accordance with t
46、he ISO 16890 series, the fractional efficiency values shall always be compared among the same ePMxclass (ex. ePM1of filter A with ePM1of filter B). The test dust capacity and the initial arrestance of a filter element are determined as per the test procedures defined in ISO 16890-3.vi ISO 2016 All r
