16、ormity with the protection requirements of the Electromagnetic Compatibility Directive (89/336/EEC). The purpose of this product family standard is to establish uniform requirements for the electromagnetic immunity of the machine tools contained in the scope, to fix test specifications of immunity,
17、to refer to basic standards for methods of testing, to standardise conditions during the tests, performance criteria and test report format for the assessment of conformity. Annexes designated “normative“ are part of the body of the standard. Annexes designated “informative“ are given for informatio
18、n only. In this standard, Annexes A, B and C are normative and Annexes D and E are informative. _ 3 EN 50370-2:2003 Contents 1 Scope.4 2 References 4 2.1 Normative references4 2.2 Other references .5 3 Terms, definitions and abbreviations 5 3.1 Terms and definitions5 3.2 Abbreviations 6 4 System con

22、machine tools designed exclusively for industrial and similar purposes that use electricity, the rated voltage of the machine tool not exceeding 1 000 V a.c. or 1 500 V d.c. between lines. Machine tools may incorporate motors, heating elements or their combination, may contain electric or electronic
23、 circuitry, and may be powered by the mains, or any other electrical power source. This immunity standard may also be used for assessment of equipment used in other environments, which require less stringent immunity levels (residential, light industry) than the industrial environment. This standard
24、 is not intended for the EMC conformity assessment of modules to be placed on the market separately. This standard is not intended for complying with Machinery Directive 98/37/EC. Hence safety considerations are not covered by this standard. This standard does not cover fixed installations as define
25、d in the Guide to the Application of Directive 89/336/EEC, published by the European Commission. This standard does not apply to apparatus intended to be used in locations where special electromagnetic conditions prevail, such as the presence of high electromagnetic fields (e.g. in the vicinity of a
26、 broadcast transmitting station) or where high pulses occur on the power network (e.g. in a power generator station). In these instances special mitigation measures may have to be employed. Immunity requirements in the frequency range 0 Hz to 400 GHz are covered. No measurements need to be performed
27、 at frequencies where no requirements are specified. 2 References 2.1 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed
