适用范围：This part of IEC 61508 provides information on– the underlying concepts of risk and the relationship of risk to safety integrity (see AnnexA);– a number of methods that will enable the safety integrity levels for the E/E/PE safetyrelatedsystems to be determined (see Annexes C, D, E, F and G).The method selected will depend upon the application sector and the specific circumstancesunder consideration. Annexes C, D, E, F and G illustrate quantitative and qualitativeapproaches and have been simplified in order to illustrate the underlying principles. Theseannexes have been included to illustrate the general principles of a number of methods but donot provide a definitive account. Those intending to apply the methods indicated in theseannexes should consult the source material referenced.
