EN 12198-2:2002+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 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 radiation 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, designers 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 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 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 will 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 document 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 provisions 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 radiation emissions as defined in EN 12198-1. This standard applies to machinery as defined in 3.1 of EN 292-1:1991. SIST EN 12198-2:2003+A1:2008

Additional definitions specifically needed for this standard are contained in EN 12198-1:2000. 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 conditions 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, hydraulic 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 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 during which radiation measurements are made SIST EN 12198-2:2003+A1:2008



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 which 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 shall 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 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 without adequate protection. This estimation should also prevent overloading of measurement equipment. 6.2 Measurement apparatus Accuracy, measuring range, selectivity, directionality, time resolution, and s
