The results are that fine dust can be a serious health hazard, contri
39、buting 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 PM10, PM2,5and PM1. The U.S. Environmental Protection Agency (EPA), the World Health Organization (WHO) and the
40、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. However, this definition is not precise if there is no further characterization of the sampling method and the s
41、ampling 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 on the collection on a filter of the PM10fraction of ambient particulate matter and the gravimetric mass determi
42、nation (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. EPA or the German Federal Environmental Agency (Umweltbundesamt), increasingly use in their publications the more
43、 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 impact on a filter elements particle removal efficiency, the ISO 16890 series refers to this simplified definitio
44、n 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 symbol ePMxdescribes the efficiency of an air cleaning device to particles with an optical diameter between 0,
45、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 efficiencies , ePMxEfficiency Size range, mePM100,3 10ePM2,50,3 2,5ePM10,3 1Air filters for general ventilation ar
46、e widely used in heating, ventilation and air-conditioning applications of buildings. In this application, air filters significantly influence the indoor air quality and, hence, the health of people, by reducing the concentration of particulate matter. To enable design engineers and maintenance pers
47、onnel 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 to their particle efficiencies, especially with respect to the removal of particulate matter. Current regional
48、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. Additionally, the current industry standards have known limitations by generating results which often are far away from fi
49、lter 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 adopted, 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
