Machine designers are obliged to eliminate risks before considering further measures to reduce or control risks (EN ISO 12100). Amendment of EN ISO 13849-1 (October 2015) Page 4 of 9 • In Categories 2 and 3: adequate measures against CCF, and for each component DC at least "low". • In Category 4: adequate measures against CCF, and for each component DC "high". The following additional information is provided: 2011-08-18 2014-11-22 –PL=d with structure category 3 as described in ISO 13849-1:2006, OR –SIL 2 with a hardware fault tolerance of 1 with a proof test interval of not less than 20 years, as described in IEC 62061:2005. ANSI RIA 15.06-2012 Section 5.4 As the successor to EN 954-1, EN ISO 13849-1 is the main safety standard for the design of safety-related control systems for machinery. Performance Level In contrast to the previous standard EN 954-1, which took a deterministic (reproducible) approach, EN ISO 13849-1 is based on a probabilistic approach to assessing safety-related control systems.

High risk. Low risk. Starting point to gauge risk reduction performance level PLr. If Performance Levels (PL) d or e are to be achieved, it should be noted that the requirements for the safety architecture for Category 3 or 4 are sometimes higher. Performace Level (PL)is reduced with a series connection of safety switches but EN ISO 13849-1 requires for Cat. 3 or Cat. 4 that every first fault is detected by Jul 23, 2019 The January 2019 draft of ISO 13849-1 also contained minimum HFT λD with credit only allowed up to a DC of 90% for a CAT 3 architecture.

ISO 13849 – 1 is a simplified method for determining the reliability of safety-related controls for machinery. The basic ideas came from IEC 61508 , a seven-part standard originally published in 1998.
