Electromagnetic compatibility (EMC) - Generic standards - Part 8: Emission standard for professional equipment in commercial and light-industrial locations 1 Scope This document is applicable only if no relevant dedicated product or product family EMC emission standard has been published. This document for emission requirements applies to electrical and electronic equipment intended for use in commercial and light-industrial (see 3.1.3) locations. This document applies to equipment that satisfy the following restrictions of use: ——is defined as professional equipment (see 3.1.13), ——is professionally installed and maintained (see 3.1.14 and Clause 6), ——is not intended to be used in residential locations (see 3.1.16). IEC 61000-6-3 applies to electrical and electronic equipment intended for use at commercial and light-industrial locations that do not satisfy these restrictions. The intention is that all equipment used in the residential, commercial and light-industrial environments are covered by IEC 61000-6-3 or IEC 61000-6-8. If there is any doubt, the requirements in IEC 61000-6-3 apply. Emission requirements within the frequency range 0 Hz to 400 GHz are covered. The conducted and radiated emission requirements in the frequency range up to 400 GHz are considered essential and have been selected to provide an adequate level of protection of radio reception in the defined electromagnetic environment. Not all disturbance phenomena have been included for testing purposes but only those considered relevant for the equipment intended to operate within the locations included within this document. The emission requirements in this document are not intended to be applicable to the intentional transmissions and their harmonics from a radio transmitter as defined by the ITU. NOTE 1: Safety considerations are not covered by this document. NOTE 2: In special cases, situations will arise where the levels specified in this document will not offer adequate protection; for example where a sensitive receiver is used in close proximity to an equipment. In these instances, employ special mitigation measures to reduce any impact. NOTE 3: Disturbances generated in fault conditions of equipment are not covered by this document. NOTE 4: Equipment which complies with IEC 61000-6-3 are suitable for use within these defined locations. 2 Normative references The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document.
