This 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. As well as dealing with electrical, electronic and programmable electronic systems, the standard also considers other control technologies, such as fluid power for example Note that the EN 13849-1 MTTFd is used on single channesl before diagnostics and structure is considered, not the final result. It would be possible to calculate this value, but it is only relevant if the internal IQAN-MC3 electronics was to be analyzed again using the so called "Simplified procedure for estimating PL" in EN 13849-1.

EN 15011 for bridge and portal cranes still kept EN 954-1 as the relevant norm for the safety of the electrical equipment of the crane. This EN ISO 13849-1:2015: MTTF D = B 10D 0.1 x n op B 10D = Mean number of cycles in which up to 10% of the components have failed in a dangerous manner. n op = Mean number of annual actuations. Notice: According to EN ISO 13849-1:2015, higher MTTF D values can be assumed with a limited number of operations per year: n op MTTF D > 1,000,000 150 years For hydraulic components, the standard ISO 13849-1:2015 stipulates an MTTF D value of 150 years, assuming that basic and well-tried safety principles are applied.

MTTFd (EN ISO 13849) or PFHd (IEC 61508) values are provided Tables from EN ISO 13849-1 to establish the performance level.

New declarations of conformity referencing EN ISO 13849-1 and EN1175-1:1998+A1:2010 will be made available for the controllers listed above, to provide presumption of conformity from Jan. 1, 2012 and beyond. EN ISO 13849-1:2006 introduces the performance levels from PL a (lowest) to PL e (highest) and is determined by: • EN ISO 13849 categories (Cat B, Cat 1,….Cat 4) • Diagnostic Coverage (DC) • Mean Time To Dangerous Failure (MTTF d) The first two parameters relate to the control system, meanwhile MTTF d stands for the quality and David Collier of Pilz Automation Technology explains the changes that were introduced in the third edition of BS EN ISO 13849-1, published in December 2015, which is identical to international standard ISO 13849-1:2015 and European harmonised standard EN ISO 13849-1:2015.
