ISO 13849-1 is a revised version of EN 954-1. The complex mathematical formulas of the system reliability theory were replaced with pre-calculated tables. Some concepts of EN 954 were retained, i.e. categories, redundancy, monitoring. A number were modified, i.e. risk graph, selection of Categories.

· EN 13849-1, SIL-2, PL-D, MTTFd etc and what does it mean for Crane Safety Systems? MTTFd (EN ISO 13849-1) and are therefore not a result of a conversion by for example, PFH in MTTFd or the comparative tables from EN ISO13849-1:2008. Therefore. MTTFd (EN ISO 13849) or PFHd (IEC 61508) values are provided Tables from EN ISO 13849-1 to establish the performance level. The relationship   Determined methods for category of SRP/CS, MTTFd, DCavg and CCF were reported. 一般可通过ISO 13849-1：2006提供的简化程序来实现，如图3所示。 6- Standard EN ISO 13849-1 and the new parameters: PL, MTTFD, DC, CCF EN ISO 13849-1 also uses a risk graph for the risk analysis of a machine function   also published as ISO 13849-1 : 1999 changed number to EN ISO 13849-1 ( 2006) Structure (Category), Reliability (MTTFd) and Diagnostics (DC).

EN ISO 13849-1:2008 har publicerats som harmoniserad standard mot maskindirektivet 2006/42/EG i EU:s officiella tidning. Därmed gäller presumtionen om överensstämmelse. 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.
