1 Scope

This Technical Specification establishes a methodology for the achievement of functional safety only with regard to electromagnetic phenomena of electrical and electronic systems and installations, as installed and used under operational conditions. This methodology includes the implication it has on equipment used in such systems and installations.

2 Normative references

The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. IEC104 Guidance.1997, The preparation of safety publications and the use of basic safety publications and group safety publications

3 Terms, definitions and abbreviations

For the purposes of this document, the definitions contained in IEC 60050 (161) as well as the following apply. ability of an equipment or system to function satisfactorily in its electromagnetic environment without introducing intolerable electromagnetic disturbances to anything in that environment

4 General considerations

Electromagnetic disturbances can influence the performance of equipment and the functional safety of systems.

5 The achievement of functional safety

The overall lifecycle relevant for the functional safety of safety-related E/E/PE systems is defined in IEC 61508, and shown in Figure 1.

6 The electromagnetic environment

Relevant and significant information exists within the EMC body of publications regarding the electromagnetic environment present where most electrical or electronic equipment operates.

7 EMC aspects of the design and integration process

The electromagnetic environment in the place where the safety-related system is used shall not unacceptably affect its functional safety. This requires that the level of immunity of the safety-related system is sufficient for the intended safety integrity and electromagnetic environment, over its lifetime. 8 Verification/validation of immunity against electromagnetic disturbances for functional safety The objective of verification is to confirm and to demonstrate that the deliverables of each phase meet in all respects the requirements of that phase. Hence verification is performed within the individual phase and is related to the levels below the overall system level. for example, equipment level or component level.

9 EMC tests for functional safety

Usually, the functional immunity tests in a product or generic standard do not consider all of the possible electromagnetic phenomena (as listed in Table A.1). It is also conceivable that a high-level electromagnetic disturbance that has not been taken into account could have a safety implication. ......
