EN ISO 13849-1 revideras för närvarande och man räknar med att publicera den bearbetade versionen som ny EN ISO 13849-1 i början av 2016 och godkänna den för tillämpning genom harmonisering mot 2006 /42/EG. ISO 13849 is a safety standard which applies to parts of machinery control systems that are assigned to providing safety functions (called safety-related parts of a control system). ISO 13849-1, Part 1: General principles for design, provides safety requirements and guidance on the principles of design and integration of safety-related parts of The combination of Category plus DC avg adopted, is shown in one of the seven columns of fig. 5 of ISO 13849-1. Calculated MTTF d determines which part of the column is to be considered. Corresponding PL is shown on the left of the table.

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. A significant property of a “Category 3” architecture is that a single fault cannot lead to loss of the safety function. (See ISO 13849-1 for more details).
