4、on 1 November 2008. DIN EN 12198-2:2003-04 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 Europea
5、n legislation (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
6、in its preparation was the Normenausschuss Sicherheitstechnische Grundstze (Safety Design Principles Standards Committee), Section 1 Sicherheitstechnik. This standard concretizes the basic requirements set out in Annex I of the EU Machinery Directive 98/37/EC (valid until 28 December 2009) and the n
7、ew 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 harmonized standard in the Official Journa
8、l 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”). Amendments This standard differs from DIN EN 12198-2:2003-04 as follows: a) The French title (main element) has been corr
9、ected. b) Some corrections have been made to the German translation. c) Inclusion of Annex ZB (informative) “Relationship between this European Standard and the Essential Requirements of EU Directive 2006/42/EC”.

DIN EN 12198-2:2008-11 EN 12198-2:2002+A1:2008 (E) 4 Introduction Machinery supplied by electrical power or containing radiation sources may emi
25、t radiation or generate electric and/or magnetic fields. The radiation emissions will vary in frequency and magnitude. EN 12198-1 contains the general principles of risk assessment of radiation emission by machinery. EN 12198-3 contains details of protective measures for avoiding or reducing radiati
26、on exposure of persons by reducing emissions and requiring the provision of information. Designers should identify the radiation hazards arising from machinery in accordance with the general principles set out in EN 12198-1. In order to assess the risks and categorize the radiation emissions, design
27、ers need to quantify the hazards. Measurements are made in accordance with the following clauses in order to: check the level of safety integration in the design of machinery; give a basis for the categorization according to 7.1 of EN 12198-1:2000; assess the ability of machinery to be operated, set
28、 and maintained without any hazard to persons when setting and maintenance operations are carried out under the conditions specified by the manufacturer; detect and measure, any radiation leakage; determine areas where radiation emissions may create a health and safety hazard; enable potential users
29、 to make comparisons of the radiation emission from different machines. In case of particular difficulties, measurements can be supplemented by duly justified calculations. Annex A gives information about the techniques of measurement of the different types of radiations. The standard techniques wil
30、l be specified in other standards as they are developed. Other methods and detectors can be developed, their omission from this annex does not exclude their use. If no standard measurement techniques exist, then an accepted scientific procedure should be applied and appropriate details given. This d
31、ocument is a type B standard as stated in EN 1070. The provisions of this document may be supplemented or modified by a type C standard. NOTE For machines which are covered by the scope of a type C standard and which have been designed and built according to the provisions of that standard, the prov
32、isions of that type C standard take precedence over the provisions of this type B standard. 1 Scope This European Standard defines basic technology and specifies general procedures for making and reporting measurements of quantities related to radiation emitted by machinery. It covers the different
33、radiation emissions as defined in EN 12198-1. This standard applies to machinery as defined in 3.1 of EN 292-1:1991.

The terms and definitions given in IEC 60050-111:1996, IEC 60050-121:1998, IEC 60050-161:1990 and IEC 60050-881:1983, are also applicable. 3.1 operating conditi
39、ons conditions existing, including operating parameters, during the mode or phase of operation of the machine under test 3.2 no-load operation operation during which the machinery operates without any processed material in place, with all its components and special auxiliaries in operation (pumps, h
40、ydraulic set, suction system, etc.) and all moving parts in action (spindles, tables, carriages, etc.) within the limits of its possibilities 3.3 operation under load operation during which the machinery is running in an operational way with processed material and with all its components and special
41、 auxiliaries 3.4 phase of operation time interval during which the machine performs a particular function 3.5 operating cycle complete sequence of phases of operation from the introduction of the processed material to its removal or transfer to the next workstation 3.6 measurement time the period du
42、ring which radiation measurements are made DIN EN 12198-2:2008-11 EN 12198-2:2002+A1:2008 (E) 6 This will be specified by both the duration of the measurement and the point in time related to the phase of operation of the machine at which the measurement is made 3.7 averaging period period over whic
43、h the characterization assessment shall be made. The measured emissions are time averaged as appropriate in order to take into account any variation in emission over this averaging period 4 Classification of radiation Classification of radiation is given in clause 4 of EN 12198-1:2000. Machinery sha
44、ll be so designed and constructed that any emission of radiation is limited to the extent necessary for its operation and that the effects on exposed persons are non-existent or reduced to non-dangerous proportions (see EN 292-2:1991, annex A, subclause 1.5.10). 5 Physical quantities to be measured
45、The physical quantities to be measured and their associated units are given in annex B of EN 12198-1:2000. 6 Measurement procedure 6.1 Warning Before carrying out measurements, estimates of the level of emission should be made to ensure that persons are not exposed to hazardous radiation emission wi
46、thout adequate protection. This estimation should also prevent overloading of measurement equipment. 6.2 Measurement apparatus Accuracy, measuring range, selectivity, directionality, time resolution, and spectral sensitivity of the measurement device shall be appropriate to measure the radiation emi
47、ssion and enable the result to be compared with the specified radiation emission category values, given in annex B of EN 12198-1:2000. The selection of the measurement equipment and the procedure shall be made so that the introduction of the equipment or the presence of the person carrying out the m
48、easurement do not significantly perturb the radiation field under consideration. The calibration of the measurement equipment shall be traceable according to the relevant national calibration standards. 6.3 Procedures 6.3.1 General Measurements shall be performed in conditions such that there are no
49、 reflections or they can be neglected, so that the radiation emissions will not be overestimated. The area around the machine shall be cleared of any objects not required for the machines operation and which might hinder the free propagation of the radiation(s) to be measured. 6.3.2 Operating conditions During measurement, the specified operating conditions shall be representative of the greatest emission of radiation during intended use of the machinery.
