DESCRIPTION

BS EN 61508-2:2010


This standard BS EN 61508-2:2010 Functional safety of electrical/electronic/ programmable electronic safety-related systems is classified in these ICS categories:
  • 13.260 Protection against electric shock. Live working
  • 25.040.40 Industrial process measurement and control
  • 35.080 Software
  • 29.020 Electrical engineering in general
IEC 61508-2:2010 applies to any safety-related system, as defined by IEC 61508-1, that contains at least:
- one electrical, electronic or programmable electronic element;
- applies to all elements within an E/E/PE safety-related system;
- specifies how to refine the E/E/PE system safety requirements specification, developed in accordance with IEC 61508-1, into the E/E/PE system design requirements specification;
- specifies the requirements for activities that are to be applied during the design and manufacture of the E/E/PE safety-related systems except software, which is dealt with in IEC 61508-3.
These requirements include the application of techniques and measures that:
- are graded against the safety integrity level, for the avoidance of, and control of, faults and failures;
- specifies the information necessary for carrying out the installation, commissioning and final safety validation of the E/E/PE safety-related system;
- provides requirements for the preparation of information and procedures needed by the user for the operation and maintenance of the E/E/PE safety-related systems;
- specifies requirements to be met by the organisation carrying out any modification of the E/E/PE safety-related systems.
This second edition cancels and replaces the first edition published in 1998. This edition constitutes a technical revision. It has been subject to a thorough review and incorporates many comments received at the various revision stages. It has the status of a basic safety publication according to IEC Guide 104.

NEW! Also available: IEC Standards+ 61508:2010, containing all parts, together with a commented Redline version. Changes made in this 2nd edition are highlighted and commented by a leading world expert.

This publication is of high relevance for Smart Grid.
