4、 1 November 2008. DIN EN 1093-8:1998-11 may be used in parallel until 28 December 2009. National foreword This standard includes safety requirements within the meaning of the Gerte- und Produktsicherheitsgesetz (GPSG) (German Equipment and Consumer Goods Safety Law) and in connection with European l
5、egislation (EC Machinery Directive), which has been implemented by national legislation. This standard has been prepared by Technical Committee CEN/TC 114 “Safety of Machinery” (Secretariat: DIN, Germany) in connection with the amended EC Machinery Directive. The responsible German body involved in
6、its preparation was the Normenausschuss Sicherheitstechnische Grundstze (Safety Design Principles Standards Committee), Technical Committee NA 095-03-01 AA Mess-strategien und Anforderungen an Messverfahren, Working Group NA 095-03-01-02 AK Stoffemittierende Maschinen. This standard concretizes the
7、basic requirements set out in Annex I of the EU Machinery Directive 98/37/EC (valid until 28 December 2009) and the new EU Machinery Directive 2006/42/EC which becomes applicable on 29 December 2009 relating to machinery to be placed on the EEA market, with the intent of simplifying the means of pro
8、ving conformity with such requirements. Once this standard is designated a harmonized standard in the Official Journal of the European Union, a manufacturer applying this standard may assume compliance with the requirements of the Machinery Directive (the so-called “presumption of conformity”). This
9、 standard makes reference to documents which were valid as of the publication of the European standard. Since then, ENV 1070:1993 has been withdrawn. It is now recommended to make reference to DIN EN ISO 12100-1, Safety of machinery Basic concepts, general principles for design Part 1: Basic termino
10、logy, methodology. Further, it is recommended to replace EN 292-1:1991 by DIN EN ISO 12100-1 as well as EN 292-2:1991 and EN 292-2/A1:1995 respectively by DIN EN ISO 12100-2, Safety of machinery Basic concepts, general principles for design Part 2: Technical principles. Amendments This standard diff
11、ers from DIN EN 1093-8:1998-11 as follows: a) Deletion of the previous Annex ZA (informative) concerning the relationship between this European Standard and the Essential Requirements of EU Directive 89/392/EEC. b) Inclusion of Annex ZA (informative) “Relationship between this European Standard and
12、the Essential Requirements of EU Directive 98/37/EC”. c) Inclusion of Annex ZB (informative) “Relationship between this European Standard and the Essential Requirements of EU Directive 2006/42/EC”.

DIN EN 1093-8:2008-11 EN 1093-8:1998+A1:2008 (E) 4 Introduction This European Standard is a type B standard as stated in ENV 1070:1993. This European Standard is a part of EN 1093. Par
27、t 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 airborne hazardou
28、s 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. Measurement
29、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 materials pr
30、ocessed), 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 or undated ref
31、erence, 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 when incorpo

35、s European Standard the definitions of ENV 1070:1993 and the following definition applies: 3.1 pollutant concentration parameter, cabin, Pcc the measured concentration of a specified pollutant in defined position(s) near the machine. For the purpose of this European Standard one measurement point sh
36、all 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 concentration at a well defined location (see 5.2) for a specified exhaust air flow rate of the test bench. This co
37、ncentration gives an indication of the emission from the machine. DIN EN 1093-8:2008-11 EN 1093-8:1998+A1:2008 (E) 6 5 Test bench 5.1 Description of the test bench The test bench consists of a cabin with a funnel and a subsequent air mover (see figure 1).

39、 Figure 1 Test bench (schematic layout) The air mover produces an air flow in the test 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 in
40、let and to avoid the escape of the pollutant from the cabin. The cabin exhaust flow 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
41、 cross section area of the machine shall not exceed a fifth of the cross section area of the cabin. 1) Generally the source cannot be considered as a point, but as a zone including several sources. DIN EN 1093-8:2008-11 EN 1093-8:1998+A1:2008 (E) 7 The cabin shall be long enough to accommodate the m
42、achine 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 cabin at a distance of
43、 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 and/or are only suita
44、ble 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 working procedures, the t
45、ools 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 located in the cabin
46、 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 to these instructio
47、ns. 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 European standards. Detai
48、led 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 operational cycles
49、 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.
