Scope: IEC 61508-5:2010 provides information on the underlying concepts of risk and the relationship of risk to safety integrity (see Annex A); a number of methods that will enable the safety integrity levels for the E/E/PE safety-related systems to be determined (see Annexes C, D, E, F and G). The method selected will depend upon the application sector and the specific circumstances under consideration. Annexes C, D, E, F and G illustrate quantitative and qualitative approaches and have been simplified in order to illustrate the underlying principles. These annexes have been included to illustrate the general principles of a number of methods but do not provide a definitive account. Those intending to apply the methods indicated in these annexes should consult the source material referenced. 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.<br /> <br /><span style='color:red'>NEW!</span> Also available: <a href="http://webstore.iec.ch/webstore/webstore.nsf/standards+ed/S+ IEC%2061508%20Ed.%202.0?OpenDocument"> IEC Standards+ 61508:2010</a>, containing all parts, together with a commented Redline version.
