DD IEC/TS 61000-1-2:2008 Electromagnetic compatibility (EMC). General. Methodology for the achievement of functional safety of electrical and electronic systems including equipment with regard to electromagnetic phenomena

DD IEC/TS 61000-1-2 establishes a methodology for the achievement of functional safety with regard to electromagnetic phenomena of electrical and electronic systems and installations. It mainly covers EMC related aspects of the design phase of safety-related systems and equipment used therein, and deals in particular with:

• Some basic concepts in the area of functional safety
• The various EMC specific steps for the achievement and management of functional safety
• The description and assessment of the electromagnetic environment
• The EMC aspects of the design and integration process taking into account the process of EMC safety planning on system as well as on equipment level
• The validation and verification processes regarding the immunity against electromagnetic disturbances,
• The performance criterion and some test philosophy considerations for safety-related systems and the equipment used therein
• Aspects related to testing of the immunity of safety-related systems and equipment used therein against electromagnetic disturbances.

This Technical Specification is also applies to safety-related systems intended to comply with the requirements of BS IEC 61508 and/or associated sector-specific functional safety standards. This Technical Specification may also be used as a guide for considering EMC requirements for other systems having a direct contribution to safety.

The main changes to DD IEC/TS 61000-1-2 include:

• For safety-related systems that use electrical, electronic or programmable electronic technologies, the technical information, definitions, terminology and text of this second edition have been aligned to IEC 61508.
• Risk assessment requirements and methodologies have been deleted from this document, so as not to duplicate or clash with IEC 61508.
• It now makes a clear distinction between complete safety-related systems and items of equipment that might be used in such systems, and clarifies its application by the different types of end-users.
• This technical specification focuses more on appropriate design methods, and their verification and validation.
• The methodology for assessing and specifying electromagnetic environments has been extended.
• The combination of electromagnetic and physical/climatic influences are taken into account.
