The main reason for that was to also consider the importance of failures-in-time of the design and its components, not only its architecture as for 954-1. However, the machine norms, e.g. 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. 2011-12-09 components according to EN ISO 13849-1 und IEC 62061 SRP/CS Values according to EN ISO 13849-1 Values according to IEC 62061 Eaton type B10 d [opera-tions] MTTF d [years] PL B10 [opera-tions] PFH d SIL CL Input Emergency switching off, turn-release M22-PVT..

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 13849-1 MTTFd = 134.8 years instantaneous safety outputs EN/ISO 13849-1 MTTFd = 54.5 years time delay safety outputs EN/ ISO 13849-1 DC > 98.4 time delay safety outputs EN/ISO 13849-1 PFHd = 6.81E-9 1/h instantaneous safety outputs EN/IEC 62061 PFHd = 1.96E-8 1/h time delay safety outputs EN/ IEC 62061 Type of start Configurable Determining B10 values for pneumatic components according to ISO 19973 e converting a B10 value into an MTTFd value EN ISO 13849-1 Definition of the B10 value Statistically expected value for the number of cycles at which 10% of the components have exceeded the limit values defi ned for the test (switching time, leakage, switching pressure etc.) under specifi c conditions.

operations where 10% of the components fail to danger. The corresponding MTTFd value is calculated from the B 10d value and the switching cycles of the component (see EN ISO 13849-1). Measures to take to combat common cause failures (CCF) are described in EN ISO 13849-1, such as: Physical separation between the signal paths Diversity
