21、, excluding electro discharge machines (EDM), designed exclusively for industrial and similar purposes that use electricity, the rated voltage of the machine tool not exceeding 1 000 V AC or 1 500 V DC between lines. Machine tools may incorporate motors, heating elements or their combination, may co
22、ntain electric or electronic circuitry, and may be powered by the mains, or any other electrical power source. This standard does not cover fixed installations as defined in the Guide to the Application of Directive 89/336/EEC, published by the European Commission. Emission requirements in the frequ
23、ency range 9 kHz to 400 GHz are covered. No measurements need to be performed at frequencies where no requirements are specified. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications.

30、ine-interface, programmable logic controller - PLC, power drive.), intended exclusively for an industrial assembly operation for incorporation in an apparatus or system. A component can be considered as a module 3.3 electromagnetically relevant component/module An electromagnetically relevant compon
31、ent or module for emission aspects is defined as one that, due to its electromagnetic characteristics, is liable to cause electromagnetic disturbances such that it will influence the emission characteristics of typical assemblies into which it may be incorporated 3.4 port particular boundary of the
32、specified machine tool or module with the electromagnetic environment of the process (IEV 131-02-21 modified) NOTE By boundary is meant the physical limits of the complete machine tool or module. 3.5 power interface connections needed for the distribution of electrical power within the machine tool

39、pe testing of a finished product is the normal method for conformity assessment against the requirements of a standard, but complete testing of an entire machine tool at a conventional EMC test site is only technically possible and economically feasible for a limited number of machines. A distinctio
40、n shall be drawn between type-testable machines and machines which, because of the weight, dimensions, operation or unreasonable testing costs and testing delay, cannot be type-tested as a whole at a conventional EMC test site. Furthermore, it is necessary to take into account single-piece productio
41、n and the multitude of types as well as expansions and modifications. Distinctions shall be drawn between the following cases and shall be taken into account: type-testable machines; machines which are not type-testable; multitude of types; modifications, additions and expansions. Each testing proce
42、dure for conformity assessment is based on one or a combination of various tests: type test at the EMC test site; visual inspection of entire machine tool; additional tests on entire machine tool 1) . 1)Such tests are usually performed in the manufacturers premises. 7 EN 50370-1:2005 5 Emission meas
43、urements Emission measurements shall be performed in accordance with EN 55011 and CISPR 16. The content of these standards are not repeated here however modifications or additional information needed for the practical application of the testing procedures are given in the present product standard. (
44、These conditions may include in situ measurements as long as they are in accordance with the test methods specified in EN 55011 and CISPR 16). 5.1 Classification and testing procedures The emission testing procedures are described in the following paragraphs. A flow chart providing an overview of th
45、e test procedures is included in the informative Annex E. 5.1.1 Machine tool containing no electromagnetically relevant components If the machine tool contains no electromagnetically relevant components, no tests have to be carried out. EXAMPLES Machine tools containing only components such as squir
46、rel cage motors and electromechanical switches. 5.1.2 Machine tool containing electromagnetically relevant components If the machine tool contains electromagnetically relevant components such as electronic control and power parts (sub-assemblies, sub-systems, etc.), one of the procedures laid down i
47、n Table 1 shall be carried out. The test procedure is chosen by the manufacturer based on the characteristics of the machine tool.

49、achine tool shall be tested according to the emission requirements laid down in this standard (see 5.2 to 5.4 and Annex A). During measurement, the machine tool shall operate as specified by the manufacturer. 5.1.2.2 Test procedure B The entire electrical set of the machine tool shall be tested according to the specific emission requirements laid down in this standard (see 5
