The IEC 61000-6-8 is an EMC emission standard for professional equipment used in commercial and light-industrial locations. This EMC emission standard specifies the EMC emission requirements for electrical and electronic equipment intended for use in commercial and light-industrial locations/environments. This generic EMC emission standard is to be used if NO applicable/relevant product or product family EMC emission standard is available. 

This EMC emission measurement standard specifies the EMI emission limit for equipment test procedures, and other related details for emission measurement tests. This standard ensures that the electrical and electronic products used in commercial, and light-industrial environments do not emit more than the EMI emission limit specified in this standard and do not interfere with other devices or systems in the same environment. 

This EMC document covers the emission requirements within the frequency range of 0 Hz to 400 GHz. This part of IEC 61000 includes the conducted and radiated emission requirements in the frequency range of up to 400 GHz. This standard not included all disturbance phenomena for testing purposes. But, this EMC standard only includes those considered relevant for the equipment intended to operate within the environments. All equipment used in the residential, commercial, and light-industrial environments/locations are covered by EMC standard IEC 61000-6-3 or IEC 61000-6-8. If there is any doubt, the emission requirements in IEC 61000-6-3 document apply. 

NOTE 1: This document/standard does not apply to intentional transmissions and their harmonics from a radio transmitter as defined by the ITU (International Telecommunication Union). 

NOTE 2: This standard does not cover safety considerations.

NOTE 3: In some situations or special cases, the emission level specified in this document will not offer adequate protection; for example, where a sensitive receiver is used in close proximity to equipment. In such cases, special mitigation measures can be employed.

NOTE 4: Disturbances generated due to fault conditions of equipment are not covered by this document.

NOTE 5: Equipment that complies with IEC 61000-6-3 EMC standard are suitable for use within these defined locations.
