26、uction This European Standard is a type B standard as stated in ENV 1070:1993. This European standard is a part of EN 1093. Part 1 of this standard presents a selection of different methods for the evaluation of the emission of airborne hazardous substances from machines. 1 Scope This European Stand

27、ard specifies a test rig method for the measurement of the separation efficiency by mass of air cleaning systems, operating under defined conditions. The method shall apply to systems that clean air of aerosols (smoke, dust, fume, mist), vapour or gas with defined air inlet and air outlet which can

28、be connected to measurement ducts. Measurement of the separation efficiency by mass of an air cleaning system for an intended use can serve for the: a) evaluation of the performance of an air cleaning system; b) evaluation of the improvement of the air cleaning system; c) comparison of air cleaning

29、systems; d) ranking of air cleaning systems according to their separation efficiency by mass; e) determination of the state of the art of air cleaning systems of the same intended use with respect to their separation efficiency by mass. 2 Normative references This European Standard incorporates by d

For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standar

34、lies: 3.1 separation efficiency by mass s The separation efficiency of an air cleaning system for a specified pollutant is the ratio of the mass of pollutant retained by the air cleaning system (m3) to the mass of pollutant entering the air cleaning system (m1) during a given period. The separation

35、efficiency of air cleaning systems in percentage is expressed as follows: 10013=mms (1) 4 Principle The principle of the measurement method is to operate the air cleaning system under defined conditions and to determine the mass of the test substance in the air upstream and downstream of the air cle

36、aning system. NOTE The test substance, which may be the real pollutant or a surrogate, should preferably be of low toxicity and compatible with the objectives of the method. 5 Description of the test arrangement The test arrangement consists of the air cleaning system fitted with suitable inlet and

37、outlet ducts (see figure 1). If it is necessary to use an additional air mover, it shall be connected to the outlet duct. The air volume flow rate shall be set in accordance with the air cleaning system manufacturers instructions for use. 1 inlet duct 5 outlet duct 2 injection point(s) of test subst

The test substance is

39、introduced into the inlet duct by a suitable method. The air in the inlet duct shall be filtered so that it contains no substance that may influence the test result. 6 Operation of the air cleaning system The air cleaning system shall be operated according to its intended use and with a specified te

40、st substance. For given categories of air cleaning systems the test substance (e.g. nature, particle size distribution) and its upstream concentration shall be defined in the type C standards. Air cleaning system shall be operated in accordance with the manufacturers instructions for use. 7 Procedur

41、e The mass flow rate of the test substance shall be measured or determined in the inlet measurement planes 1 and 2 (see figure 1) during the test period from times t1to t2The measurement procedures used shall comply with appropriate international or European standards. For the measurement of the air

42、 flow rate see ISO 3966:1977, ISO 4006:1991, ISO 4053-1:1977, ISO 5167-1:1991, ISO 5168:1978 and 7145:1982. The same type of instrument should be used upstream and downstream of the air cleaning system. If this is not possible, the relationship between the two instruments shall be established for ea

43、ch test substance used. For certain applications it is useful to determine the separation efficiency according to particle size distribution (see EN 481). The separation efficiency of some air cleaning systems changes with time e.g. filters. The sampling procedure shall take into account these chang

44、ing efficiencies in order to obtain valid information about the efficiency of the separator in use. The measurement time shall be of sufficient duration to collect samples of the substance emitted during the representative use of the air cleaning system including e. g. several cycles of the operatio

45、ns of a filter cleaning mechanism. Detailed test conditions and statistical analysis of the results shall be specified in appropriate type C standards. 8 Expression of results The mean value of the separation efficiency of an air cleaning system is calculated according to the following formula: 1001

46、10011001212132121=dtCdtCmmmmtttts (2) where: m1is the mass of the test substance entering the air cleaning system; m2is the mass of the test substance not retained by the air cleaning system; DIN EN 1093-7:2008-11 EN 1093-7:1998+A1:2008 (E) 7 m3is the mass of the test substance retained by the air c

47、leaning system; C1is the concentration of the test substance entering the air cleaning system; C2 is the concentration of the test substance at the measurement plane 2. When the separation efficiency is required as a function of particle size distribution, m1and m2are measured for each particle size

48、 range of interest. 9 Test report The test report shall include at least the following information: a) reference to this standard and appropriate type C standards; b) description of the test environment; c) description of the air cleaning system tested (e. g. manufacturer, model, type, version, desi

49、gn, size, year of manufacture, serial number); d) operational data during tests including air flow rates; e) test substance (e.g. nature, concentration, and for dusts: particle size distribution, moisture content); f) description of measurement procedures; g) measuring instruments used and their most recent calibration dates; h) environmental data (temperature, humidity, atmospheric pressure); i) description of the procedures used (e.g. list of standards) for concentration and flow rate measurements; j) test results;
