23、:2008 EN 12198-1:2000+A1:2008 (E) 4 Introduction Machinery supplied by electrical power or containing radiation sources may emit radiation or generate electric and/or magnetic fields. The radiation emissions and fields will vary in frequency and magnitude. The European Machinery Directive requires p

24、recautions to avoid or reduce risks caused by the emission of radiation from a machine. Machinery must 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-dangero

25、us proportions (EN 292-2:1991/A1:1995). To assess the risk of injury caused by radiation emissions and fields from a machine it is necessary to know the type of radiation emission, the level of the emission and the intensity of this emission with respect to possible adverse health effects. This Euro

26、pean Standard is intended to give manufacturers and type C-standards makers advice on how to identify radiation emissions from machinery, how to decide on their magnitude and significance, how to assess the risks and what means could be used to avoid or reduce the radiation emissions from machines.

27、This European Standard reflects the general principles for the identification and the assessment of radiation emission by machinery. Details of the measurement of the radiation emission will be given in part 2 of this standard. Part 3 of this standard will contain details of protective measures for

28、avoiding or reducing radiation exposure of persons by reducing emissions and requiring the provision of information. Radiation emitted by machinery may be intended for processing or may occur unintentionally. Clause 7 of this standard requires, that the manufacturer shall assign the machine to a des

29、ign radiation emission category. For undesirable radiation emission the emission level should be reduced to values corresponding to category 0. Functional radiation emission shall be limited to the necessary degree for the operation of the machine. The remaining emission levels shall be assessed and

30、 an emission category shall be determined. If necessary protective measures will have to be applied. This European Standard is a standard of B1-type in a series of standards for the safety of machinery. BS EN 12198-1:2000+A1:2008 EN 12198-1:2000+A1:2008 (E) 5 1 Scope This standard deals with the emi

31、ssion of radiation from machinery. This European Standard gives advice to manufacturers for the construction of safe machinery, if no relevant C-type standard exists. This radiation emission may be functional for processing or may be undesirable. The issues of electromagnetic compatibility are not a

32、ddressed in the standard. This European Standard is intended to give advice to C-type standardization groups, on how to identify radiation emissions or fields 1 , how to determine their significance and intensity, how to assess the possible risks and what means may be used to avoid or reduce radiati

33、on emissions. This advice should be elaborated in C-type standards for specific classes of machines as assessable requirements. This standard deals with the emission of all types of electromagnetic non-ionizing radiation. Ionizing radiation may be dealt with in other documents or in the future revis

34、ions. This standard does not deal with the emission of laser radiation. Radiation sources fixed to a machine which are used only for lighting are excluded from the scope of this standard. This standard applies to machinery as defined in clause 3.1 of EN 292-1:1991. 2 Normative references This Europe

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 publication

48、n-coherent ; polarisation. 5 General procedure The manufacturer of a machine shall carry out a risk assessment according to EN 1050. This includes the determination of the limits of the machinery, an identification of all hazards, a risk estimation and a risk evaluation. After the risk assessment me

49、asures for the reduction of unacceptable risks shall be applied if necessary. After that a repetition of the risk assessment, or only parts of it, may be necessary. For those risks which are related to the emission of radiation from a machine the procedure of risk assessment and risk reduction which shall be carried out by the manufacturer consists of: an assessment of the risks due to the emission of all types of radiation (see clause 6) ; application of appropriate measures for the elimination or reduction of the radiation
