ETSI EN 301 489-1 V1.9.2 contains the common requirements for radio communications equipment and associated ancillary equipment, in respect of Electromagnetic Compatibility (EMC).Product dependent arrangements necessary to perform the EMC tests on dedicated types of radio communications equipment, and the assessment of test results, are detailed in the appropriate product related parts of EN 301 489 series [i.13].The present document, together with the product related part, specifies the applicable EMC tests, the methods of measurement, the limits and the performance criteria for radio equipment and associated ancillary equipment. In case of differences (for instance concerning special conditions, definitions, abbreviations) between part 1 of EN 301 489 series [i.13] and the relevant product related part of EN 301 489 series [i.13], the product related part takes precedence.Technical specifications related to the antenna port of radio equipment and radiated emissions from the enclosure port of radio equipment and combinations of radio and associated ancillary equipment are not included in the present document. Such technical specifications are normally found in the relevant product standards for the effective use of the radio spectrum.The environment classification used in the present document refers to the environment classification used in:• EN 61000-6-3 [i.4] and EN 61000-6-1 [i.5] for the residential, commercial and light industrial environment; or• TR 101 651 [i.6] for the telecommunication centre environment; or• ISO 7637-2 [8] for the vehicular environment.The EMC requirements have been selected to ensure an adequate level of compatibility for apparatus intended to be used in the environments mentioned above. The levels, however, do not cover extreme cases which may occur in any location but with low probability of occurrence.Read more.
