26、troduction 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
27、Standard specifies a test rig method for the measurement of the separation efficiency by mass of air cleaning systems with unducted outlet, operating under defined conditions. The method shall apply to systems that clean air of aerosols (smoke, dust, fume, mist), vapour or gas. Measurement of the se
28、paration 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 systems; d) ranking of air cleaning systems according to
29、 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 dated or undated reference, provisions from other publica
30、tions. These normative references are cited at the appropriate places in the text and the publications are listed hereafter.

34、on 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 efficiency of an air cleaning system as a percentage i
35、s expressed as follows: 10013=mms (1) 4 Principle The principle of the measurement method is to operate the air cleaning system under defined conditions in a test rig and to determine the mass of the test substance in the air upstream and downstream of the air cleaning system. NOTE The test substanc
36、e, 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 rig The test rig consists of a cabin symmetrically connected to a measurement duct through which air is drawn (see figures 1 and 2). Fig
37、ure 1 Test rig with secondary air inlet DIN EN 1093-6:2008-11 EN 1093-6:1998+A1:2008 (E) 6 Figure 2 Test rig without secondary air inlet 1 inlet duct 6 outlet duct 2 injection point(s) of test substance 7 measurement plane 2 3 measurement plane 1 8 air mover 4 cabin 9 air cleaning system under test
38、5 funnel 10 secondary air inlet For measurement of the concentration in the inlet duct, an even distribution of the test substance shall be achieved. The air flow rate of the air cleaning system Q1, and the exhaust air flow rate, Q2, shall remain constant during the test within stated limits. The cr
39、oss section of the cabin shall be chosen according to the requirements of the air cleaning system. 6 Position and operation of the air cleaning system To optimise the transport of any pollutant emitted from the air cleaning system to the measuring plane 2 in the outlet duct, the air cleaning system
40、should normally be positioned in the cabin in such a way, that the emission from the air cleaning system is in the region of the vertical plane of the longitudinal axis of the outlet duct. Attention shall be given to the aerodynamic conditions in the cabin and duct to ensure that there is no signifi
41、cant deposition of pollutant between the air cleaning system and the measurement plane 2. 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, properties of the test substances (e. g. nature, partic
42、le size distribution) and its upstream concentration shall be defined in appropriate type C standards. The air cleaning system shall be operated in accordance with the manufacturers instructions for use. DIN EN 1093-6:2008-11 EN 1093-6:1998+A1:2008 (E) 7 7 Procedure The mass flow rate of the test su
43、bstance shall be measured in the inlet duct from times t1to t2and in the outlet duct from times t1to t3. In the inlet duct this mass flow rate can be determined from the mass of test substance feed and the air flow rate. Time t3shall be later than time t2and shall take into account the time constant
44、s of air cleaning system, cabin and outlet duct. In practical terms the difference between times t2and t3may be very short in comparison with the measurement time and may have no effect on the measurement result. The measurement procedures used shall comply with appropriate international or European
45、 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 should be used upstream and downstream of the air cleaning system. If this is not possible, the relationship between the t
46、wo instruments shall be established for each 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 pr
47、ocedure 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 sufficient duration to collect samples of the substance emitted during the representative use of the air cleaning system inc
48、luding e. g. several cycles of the operations of a filter cleaning mechanism. In general the separation efficiency of a system is dependent on the amount of retained pollutant and the air volume flow rate. Tests shall therefore be carried out with the various combinations of pollutant amounts and ai
49、r flow rates which are expected in operation. 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: 10011001100112212132131=dtCQdtCQmmmmtttts (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; m3is the mass
