28、assification system based upon particulate matter efficiency (ePM) Part 2: Measurement of fractional efficiency and air flow resistance Part 3: Determination of the gravimetric efficiency and the air flow resistance versus the mass of test dust captured Part 4: Conditioning method to determine the m

29、inimum fractional test efficiencyiv ISO 2016 All rights reservedBS EN ISO 16890-4:2016ISO 16890-4:2016(E)IntroductionThe 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 t

30、o 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 European

31、 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 sampling

32、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 determination (

33、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 simple

34、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 definition of PM1

35、0, 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 0,3 m and

36、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 are widely

37、 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 personnel to

38、 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 standard

39、s 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 filter pe

40、rformance 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

41、the equipment, materials, technical specifications, requirements, qualifications and procedures to produce the laboratory performance data and efficiency classification based upon the measured fractional efficiency converted into a particulate matter efficiency (ePM) reporting system.Air filter elem

42、ents 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 air filter elements can then be classified according to the procedures defined in ISO 16890-1. The particulate removal ef

43、ficiency 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 defined in ISO 16890-2. After the initial particulate removal efficiency testing, the air filter element is conditioned I

This is done to provide information about the intensity of any electrostatic remov

45、al 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 efficiency and the conditioned efficiency for each size range. The average efficiency is used to calculate the ePMxefficiencie

46、s 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 the ISO 16890 series, the fractional efficiency values shall always be compared among the same ePMxclass (ex. ePM1of fil

47、ter 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 rights reservedBS EN ISO 16890-4:2016INTERNATIONAL STANDARD ISO 16890-4:2016(E)Air filters for general ventilation Part

48、4: Conditioning method to determine the minimum fractional test efficiency1 ScopeThis part of ISO 16890 establishes a conditioning method to determine the minimum fractional test efficiency.It is intended for use in conjunction with ISO 16890-1, ISO 16890-2 and ISO 16890-3, and provides the related

49、test requirements for the test device and conditioning cabinet as well as the conditioning procedure to follow.The conditioning method described in this part of ISO 16890 is referring to a test device 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 ePM1efficiency less than or equal to 99 % and an ePM10efficiency greater than 20 % when tested according to the procedures defined within ISO 16890 (all parts).NOTE Th
