What is BS EN 61000-6-7 - Electromagnetic compatibility about?
BS EN 61000 is a series on Electromagnetic compatibility (EMC). 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. BS EN 61000-6-7 is intended to be used by suppliers when making claims for the immunity of equipment intended for use in safety-related systems against electromagnetic disturbances.
BS EN 61000-6-7 should also be used by designers, integrators, installers, and assessors of safety-related systems to assess the claims made by suppliers. BS EN 61000-6-7 provides guidance to product committees. BS EN 61000-6-7 applies to electrical and electronic equipment intended for use in safety-related systems and that is:
- Intended to comply with the requirements of IEC 61508 and/or other sector-specific functional safety standards
- Intended to be operated in industrial locations as described in 3.1.15
The object of BS EN 61000-6-7 is to define immunity test requirements for equipment in relation to continuous and transient, conducted, and radiated disturbances, including electrostatic discharge. These requirements apply only to functions intended for use in functional safety applications. Test requirements are specified for each port considered.
Who is BS EN 61000-6-7 - Electromagnetic compatibility for?
BS EN 61000-6-7 on Electromagnetic compatibility is useful for:
- Telecommunication component manufacturers
- Telecommunication equipment manufacturers
- Design engineers
- Quality control personnel
Why should you use BS EN 61000-6-7 - Electromagnetic compatibility?
The goal of Electromagnetic compatibility is the correct operation of different equipment in a common electromagnetic environment. It is also the name given to the associated branch of electrical engineering. BS EN 61000-6-7 is applicable in the absence of relevant dedicated product family or product standard(s) that address electromagnetic influences on functional safety. Since a product family/product standard usually gives more specific requirements, BS EN 61000-6-7 is generally considered that take precedence over the corresponding generic standard. Where a product family/product standard detailing electromagnetic influences on functional safety specifies less stringent test values for a phenomenon or if a phenomenon is only partially covered (e.g., the product family/product standard only covers a subset of the recommended frequency range), a technical justification is given in BS EN 61000-6-7.
BS EN 61000-6-7 specifies immunity testing considering the principles of Clause 9 of IEC/TS 61000-1-2:2008. It is important to note that BS EN 61000-6-7 and the process described herein is only applied in accordance with the processes detailed in IEC/TS 61000-1-2. For clarity, BS EN 61000-6-7 only applies in reference to the verification phase of the functional safety process. The achievement of tolerable functional safety risks is only achieved by fully applying the requirements. These requirements include consideration of the safety lifecycle; the development of a safety requirements specification (SRS) that includes safety function requirements and safety integrity requirements; consideration of EMC specific steps that include more than EMC immunity testing; and the management of EMC for functional safety. Using BS EN 61000-6-7 you can define immunity test requirements for equipment in relation to continuous and transient, conducted, and radiated disturbances, including electrostatic discharge.
