Scope and Object 

This Technical Report describes the electromagnetic environment. It is intended as a basis to achieve electromagnetic compatibility in system and equipment design, using test standards (techniques and limits), and mitigation methods (including installation practices), which satisfactorily take account of undesirable effects that otherwise might result from unintended electrical and electronic equipment interactions.

This report is primarily concerned with the characteristics and levels of electromagnetic fields and of non-network-frequency-related conducted emissions from unintentional sources of interference. Its application is part of the process of achieving electromagnetic compatibility of systems; this requires the immunity characteristics of equipment to be considered together with any normal or special equipment or cable installation practices that may be required. Trade-offs should be made between physical separation, filtering and shielding when considering equipment installation and design, in order to achieve emission and immunity characteristics which meet system requirements.
