What is PD IEC/TR 61000-2-5 - Electromagnetic compatibility about?
PD IEC/TR 61000 is a series on Electromagnetic compatibility. Electromagnetic compatibility is the ability of electrical equipment and systems to function acceptably in their electromagnetic environment, by limiting the unintentional generation, propagation and reception of electromagnetic energy which may cause unwanted effects such as electromagnetic interference (EMI) or even physical damage in operational equipment. PD IEC/TR 61000-2-5 introduces:
- The concept of disturbance degrees and defines these for each electromagnetic phenomena
- Classifies into various location classes and describes them by means of attributes
- Provides background information on the different electromagnetic phenomena that may exist within the environment
- Compiles tables of compatibility levels for electromagnetic phenomena that are considered to be relevant for those location classes
PD IEC/TR 61000-2-5 is intended for guidance for those who are in charge of considering and developing immunity requirements. PD IEC/TR 61000-2-5 also gives basic guidance for the selection of immunity levels. The data are applicable to any item of electrical or electronic equipment, subsystem or system that operates in one of the locations as considered in PD IEC/TR 61000-2-5.
Who is PD IEC/TR 61000-2-5 - Electromagnetic compatibility for?
PD IEC/TR 61000-2-5 on Electromagnetic compatibility is useful for:
- Telecommunication equipment manufacturers
- Telecommunication component manufacturers
- Design engineers
- Quality control personnel
Why should you use PD IEC/TR 61000-2-5 - Electromagnetic compatibility?
Knowledge of the electromagnetic environment that exists at locations where electrical and electronic equipment and systems are intended to be operated is an essential precondition in the process of achieving electromagnetic compatibility. This knowledge can be obtained by various approaches, including a site survey of an intended location, the technical assessment of the equipment and system, as well as the general literature. The descriptions of electromagnetic environments in PD IEC/TR 61000-2-5 are predominantly generic ones, considering the characteristics of the location classes under consideration. Hence, it should be kept in mind that there might be locations for which a more specific description is required in order to conclude on immunity requirements applicable for those specific locations.
Classification of the electromagnetic environment is based on the classification or a description of the electromagnetic phenomena prevailing at typical locations, not on existing test specifications. However, given a choice among equal possibilities, harmonization with existing test specifications (if appropriate) will simplify the situation and promote easier acceptance of the recommendations. The definition of the electromagnetic environment in PD IEC/TR 61000-2-5 refers to “electromagnetic phenomena”. The term "disturbance degree" is used in PD IEC/TR 61000-2-5 to quantify the phenomena contributing to the electromagnetic environment and it is independent of any consideration of test levels. The term “severity level” is not used in PD IEC/TR 61000-2-5 to describe the environment, as it is reserved for specifying immunity test levels in other IEC publications. Using PD IEC/TR 61000-2-5 you can understand the description and classification of electromagnetic environments.
