Part 1 of this stan

20、dard presents a selection of different methods for the evaluation of the emission of airborne hazardous substances from machines. 1 Scope This European Standard specifies a test rig method for the measurement of the separation efficiency by mass of air cleaning systems, operating under defined condi

21、tions. 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 be connected to measurement ducts. Measurement of the separation efficiency by mass of an air cleaning system for an intended use can serve for

22、 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 systems; d) ranking of air cleaning systems according to their separation efficiency by mass; e) determination of the state of the art of air c

23、leaning systems of the same intended use with respect to their separation efficiency by mass. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and t

28、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 efficiency of air cleaning systems in percentage is expressed as follows: 10013=mms (1) 4 Principle The principle of the measurement method

29、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 cleaning system. NOTE The test substance, which may be the real pollutant or a surrogate, should preferably be of low toxicity and compatible w

30、ith 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 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 flo

31、w 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 substance 6 measurement plane 2 3 measurement plane 1 7 air mover 4 air cleaning system under test Figure 1 Test arrangement (schematic layout) B

32、S EN 1093-7:1998+A1:2008EN 1093-7:1998+A1:2008 (E) 6 The air flow rate of the air cleaning system is measured in the inlet and outlet ducts. The test substance is 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 ma

33、y 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 test substance. For given categories of air cleaning systems the test substance (e.g. nature, particle size distribution) and its upstream

34、concentration shall be defined in the type C standards. Air cleaning system shall be operated in accordance with the manufacturers instructions for use. 7 Procedure 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

35、the test period from times t1to t2The measurement procedures used shall comply with appropriate international or European standards. For the measurement of the air 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 s

36、hould 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 each test substance used. For certain applications it is useful to determine the separation efficiency according to particle size distribut

37、ion (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 changing efficiencies in order to obtain valid information about the efficiency of the separator in use. The measurement time shall be of suff

38、icient duration to collect samples of the substance emitted during the representative use of the air cleaning system including e. g. several cycles of the operations of a filter cleaning mechanism. Detailed test conditions and statistical analysis of the results shall be specified in appropriate typ

39、e 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: 100110011001212132121=dtCdtCmmmmtttts (2) where: m1is the mass of the test substance entering the air cleaning system; m2is the mass of the t

40、est substance not retained by the air cleaning system; BS EN 1093-7:1998+A1:2008EN 1093-7:1998+A1:2008 (E) 7 m3is the mass of the test substance retained by the air cleaning system; C1is the concentration of the test substance entering the air cleaning system; C2 is the concentration of the test sub

41、stance 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 range of interest. 9 Test report The test report shall include at least the following information: a) reference to this standard and

42、appropriate type C standards; b) description of the test environment; c) description of the air cleaning system tested (e. g. manufacturer, model, type, version, design, size, year of manufacture, serial number); d) operational data during tests including air flow rates; e) test substance (e.g. natu

43、re, 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

44、 (e.g. list of standards) for concentration and flow rate measurements; j) test results; k) comments on deviations from any relevant standards; l) test laboratory; m) name of the test person responsible; n) date of testing; o) additional comments (if necessary).
