This European Standard is a part of

22、 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 Standard specifies a test bench method for the measurement of the pollutant concentration parameter of a specified airb

23、orne hazardous substance from machines using a test bench under specified operating conditions. This method is only applicable for the determination of emitted gases, vapours and respirable particles. The determination of the emission rate in a test bench (see EN 1093-3) shall be used when possible.

24、 Measurement of the pollutant concentration parameter of a machine can serve for the: a) evaluation of the performance of a machine; b) evaluation of the improvement of the machine; c) comparison of machines within groups of machines with the same intended use (groups are defined by the function and

25、 materials processed), d) ranking of machines from the same group according to their pollutant concentration parameters; e) determination of the state of the art of machines with respect to their pollutant concentration parameter. 2 Normative references This European Standard incorporates by dated o

26、r undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only

31、llutant in defined position(s) near the machine. For the purpose of this European Standard one measurement point shall be used, preferably in the duct. 4 Principle The principle of the measurement method is to operate machines under controlled conditions in a test bench and to measure the pollutant

32、concentration at a well defined location (see 5.2) for a specified exhaust air flow rate of the test bench. This concentration gives an indication of the emission from the machine.

35、est cabin from the inlet towards the funnel. The cabin shall be equipped with a permeable inlet (e. g. macroporous filter material, perforated plastic foil or plate) in order to obtain a uniform air flow across the inlet and to avoid the escape of the pollutant from the cabin. The cabin exhaust flow

36、 rate shall be specified in type C standards. It has to be controlled in order to remain constant. The cross section of the cabin (form and dimensions) shall be chosen according to the size of the machine. The maximum cross section area of the machine shall not exceed a fifth of the cross section ar

37、ea of the cabin. 1) Generally the source cannot be considered as a point, but as a zone including several sources.

38、o accommodate the machine and the operator with the emission sources as close to the specified location as practicable in figure 1. The machines shall be positioned in the cabin in such a way that the source of the pollutant emitted from the machine is in the area of the longitudinal axis of the cab

39、in at a distance of l1from the beginning of the funnel and of l0from the inlet. 5.2 Location of measurement points The concentration of the pollutant shall be measured at the measurement point 1 in the exhaust duct. If it is necessary to use measuring instruments, which have bigger sampling heads an

40、d/or are only suitable for lower air velocities, the measurement point 2, located in the area of the middle axis of the funnel as near as possible to the duct may be used. 6 Procedure 6.1 Operation of the machines The machine shall be operated according to its intended use. The stipulation of workin

41、g procedures, the tools used and the materials to be processed with specified categories of machines will be defined in type C standards. If the machine is equipped with its own separator recirculating air towards the working zone according to the intended use, the outlet of the separator shall be l

42、ocated in the cabin in such a way as to ensure that the pollutant from this secondary source reaches the measurement point. The machine shall be operated in accordance with the manufacturers instructions. When the machine is provided with pollution control equipment this shall be adjusted according

43、to these instructions. Tests shall not be carried out unless manufacturers specifications for operating the pollution control equipment are available. 6.2 Measurement procedures The measurement procedures used for the pollutant concentration shall comply with the appropriate International and Europe

44、an standards. Detailed procedures shall be specified in the appropriate type C standards for each type of machine. The measurement shall take into account the normal operational cycles of the machine. The measurement time shall be sufficient to collect concentration data representative of the normal

45、 operational cycles of the machines. As least three tests shall be performed. 7 Expression of results The pollutant concentration parameter, cabin Pcc, is the mean value and the 95 % confidence interval according to ISO 2602 of the test results.
