Project Number 22090
Abstract/Scope IEC 61508-4:2010 contains the definitions and explanation of terms that are used in parts 1 to 7 of the IEC 61508 series of standards.

However, it should be noted that these headings are not intended to add meaning to the definitions. 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.
