Electromagnetic compatibility (EMC) Part 6.7: Generic standards-Immunity requirements for equipment intended to perform functions in a safety-related system (functional safety) in industrial locations
|Publication Date:||16 December 2015|
Scope and object
This part of IEC 61000 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.
This standard should also be used by designers, integrators, installers, and assessors of safety-related systems to assess the claims made by suppliers. It provides guidance to product committees.
This part of IEC 61000 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, and
• intended to be operated in industrial locations as described in 3.1.15.
NOTE 1 The final safety-related system is designed by a system integrator (or equivalent) that has the responsibility to assess the adequacy of the equipment for the particular application. This process is described in Annex D of IEC/TS 61000-1-2:2008.
The object of this standard 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.
NOTE 2 The immunity requirements of this standard do not, however, cover extreme cases, which can occur at any location, but with an extremely low probability of occurrence. In consequence, a designer of a safety-related system checks whether the requirements of this standard cover the expected electromagnetic phenomena within the intended application.
