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 legislation (EC Machinery Directive), which has been implemented by national legisla
5、tion. 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 its preparation was the Normenausschuss Sicherheitstechnische Grundstze (Safety Des
6、ign 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 basic requirements set out in Annex I of the EU Machinery Directive 98/37/EC (valid
7、 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 proving conformity with such requirements. Once this standard is designated a harmoniz
8、ed 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 standard makes reference to EN 1070 which was valid as of the publication of the E
9、uropean standard. Since then, EN 1070 has been withdrawn.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 terminology, methodology. In Clause 2 “Normative references” DIN EN 1093-11 gives the introductory
10、text which is currently used, as opposed to the older text given in DIN EN 1093-11:2001. Amendments This standard differs from DIN EN 1093-11:2001-10 as follows: a) Editorial revision of Annex ZA (informative) concerning the relationship between this European Standard and the essential requirements

25、 This standard is a part of EN 1093. Part 1 “ Safety of machinery - Evaluation of the emission of airborne hazardous substances - Part 1: Selection of test methods” of this standard presents a selection of different methods for the evaluation of the emission of airborne hazardous substances from mac
26、hines. 1 Scope This standard describes a method for the measurement of the decontamination index of pollution control systems e. g. capture devices including local exhaust ventilation, water spray systems and, when appropriate, separation equipment installed on a machine. This method uses the real p
27、ollutant (see 4.2 of EN 1093-1 : 1998 “ Safety of machinery Evaluation of the emission of airborne hazardous substances Part 1: Selection of test methods”) and can be operated in room or field environments. It should be observed that during the test, especially during the shutdown or the removal of
28、the pollution control system, the concentration of hazardous substances , if present, can reach levels which are liable to incur a risk to the health of the operators or other occupants present in the room. Warning: This standard does not deal with the protective measures required to control these r
29、isks. Measurement of the decontamination index of pollution control system can serve for the: evaluation of the performance of a pollution control system of a machine; evaluation of the improvement of a pollution control system; comparison of pollution control systems for machines of similar design;
30、 ranking of pollution control systems according to their decontamination efficiency; determination of the air flow rate in the case of an exhaust system to achieve a given level; determination of the state of the art of pollution control systems for machines with respect to the decontamina-tion effi

36、 the average of the ratios, obtained at a number of specified locations in the surroundings, of the ambient air quality improvement1) to the real pollutant mean concentration with the pollution control system not in operation. Corrections can be necessary to take into account of air pollution caused
37、 by other operations (“the background level“) When particle size distribution is determined at the same time as pollutant concentration, a decontamination index for each size fraction can be determined (see for example EN 481 “ Workplace atmospheres - Size fraction definitions for measurement of air
38、borne particles”). 4 Principle The principle of this measurement method consists in determining the decontamination index as defined in clause 3, the concentrations being measured at predetermined points around the machinery under inspection and in interpreting the value of this index, taking into a
39、ccount its range of variation and the influencing factors. 5 Determination of concentration measurement points The measurement points will have been determined by pre-testing to ensure that they are in zones of measurable emission. The number and precise positions shall be specified in type C standa
40、rds. 6 Test method The measurement will be more accurate and the interpretation more reliable if the background level concentration is low. Whenever possible, the concentration measurements should be taken with the surrounding machinery and other processes shut down. Once the measurement points have
41、 been selected, the measurement procedure takes place in three phases. These three phases are repeated further two times. An example with two measurement points is given in figure 1. The measurement procedures used for the determination of the pollutant concentration shall comply with the ap-propria
42、te 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/TR 5168:1998 and ISO 7145:1982. Phase 1 Measurement of Cfi For the determination of the concentration level Cfi resulting from the pollutant emissi
43、on of the surrounding machinery and other processes (background level), the machine under test is shut down as well as its pollution control system if already installed. The operating conditions of the surrounding machinery and other processes are recorded. When stable conditions are reached, the co
44、ncentrations are measured at the selected points. The sampling duration at each point shall correspond to a representative fraction of the duration of the pollutant emission of the surrounding machinery and other processes. At each measurement point at least three measurements shall be made. 1) Expr
45、essed as the difference between the real pollutant concentrations measured in these surroundings with and without the pollution control system in operation. 5EN 1093-11:2001+A1:2008 (E) DIN EN 1093-11:2008-11 Phase 2 Measurement of Cmi For this phase, the machine under test is in operation. Its poll
46、ution control system is installed and in operation. The operating conditions of the machine and its associated pollution control systems shall be defined. The measurements of concentration are carried out following the same specifications as in phase 1: stable conditions, location of the measurement
47、 points, sampling duration, operating conditions of the surrounding machinery and other processes. Checks shall be carried out to confirm that, as closely as possible, the same conditions prevail as in phase 1. The sampling duration at each point shall correspond to a representative fraction of the
48、duration of the pollutant emission from the machine under test. At each measurement point at least three measurements shall be made. Phase 3 Measurement of Cai The machine under test remains in operation in the same conditions as in phase 2, but with its pollution control system shut down or removed
49、. The test cannot be performed where blockage of the extraction is likely to occur. Warning Switching off or altering the pollution control system can, in some instances, lead to exposures of operators or occupants in the room to hazardous pollutant levels. In these instances take appropriate preventive measures to minimize the risk to which the people are exposed. The measurements of concentration are carried out in a similar way to the two other phases. However, it should be observed that it can require a long stabilization time before
