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.
