Describes the electromagnetic environment intended as a basis to achieve electromagnetic compatibility in system and equipment design, using test standards and mitigation methods which satisfactorily take account of undesirable effects. The Standard is primarily concerned with characteristics and levels of electromagnetic fields and of non-network-frequency-related conducted emissions from unintentional sources of interference. It is one of a series of Standards applicable to electromagnetic compatibility. This Standard is identical with and has been reproduced from IEC 61000-2-3:1992.
