Scope

IEC 61508-1:2010 covers those aspects to be considered when electrical/electronic/programmable electronic (E/E/PE) systems are used to carry out safety functions. A major objective of this standard is to facilitate the development of product and application sector international standards by the technical committees responsible for the product or application sector. This will allow all the relevant factors, associated with the product or application, to be fully taken into account and thereby meet the specific needs of users of the product and the application sector. A second objective of this standard is to enable the development of E/E/PE safety-related systems where product or application sector international standards do not exist. 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. <span style='color:red'>NEW!</span> Also available: <a href='http://webstore.iec.ch/webstore/webstore.nsf/standards+ed/S+%2 0IEC%2061508%20Ed.%202.0?OpenDocument '> IEC Standards+ 61508:2010</a>, containing all parts, together with a commented Redline version.
