30、vBS EN ISO 16890-2:2016ISO 16890-2:2016(E)ForewordISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member b
31、ody interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electro
32、technical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of I

This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held re

39、uctionThe effects of particulate matter (PM) on human health have been 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 defin
40、ed 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 European Union define PM10as particulate matter which passes through a size-selective inlet with a 50 % efficiency cut-
41、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 sampling inlet with a clearly defined separation curve. In Europe, the reference method for the sampling and measurement
42、 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 determination (see EU Council Directive 1999/30/EC of 22 April 1999).As the precise definition of PM10, PM2,5and PM1is quite c
43、omplex 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 simple denotation of PM10as being the particle size fraction less or equal to 10 m. Since this deviation to the above
44、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 definition of PM10, PM2,5and PM1.Particulate matter in the context of the ISO 16890 series describes a size fraction of the natu
45、ral 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 0,3 m and x m. The following particle size ranges are used in the ISO 16890 series for the listed efficiency values.Table

In this application, air filters
47、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 personnel to choose the correct filter types, there is an interest from international trade and manufacturing for a well-de
48、fined, common method of testing and classifying air filters according 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
49、 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 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 adopted, which gives better and more meaningful results compared to the existing standards.The ISO 16890 series describes
