In October 2006 EN ISO 13849-1 was officially adopted as the successor standard to EN 954-1. Like EN 954-1, it incorporates the safety-related parts of control systems (SRP/CS) in its area of application and all types of machines, regardless of the technology and energy form used (electric, hydraulic, pneumatic, mechanical, etc.).

Introduction. On the 13.5.2016, EN ISO 13849-1:2015 was published in the official journal. The new standard contains a number of changes, one of which is that a new value for MTTFd is allowed 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.

According to EN ISO 13849-1:2015, the maximum mission time - complying with the oil cleanliness according to ISO 4406:1999 - is T M = 20 years. In terms of preventative maintenance, it is recommended ISO 13849-1 was prepared by the European Committee for Standardization (CEN) Technical Committee CEN/TC 114, Safety of machinery, in collaboration with Technical Committee ISO/TC 199, Safety of machinery, in accordance with the Agreement on technical … 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 13849-1 was put into place in 2006 in order to replace EN 954-1. 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.

Further, this document presumes its readers are those who are users of general-purpose PLCs and who have understood the basic contents of international safety standards. For international safety standards in general,

For hydraulic components (e.g., valves), a MTTFD value of 150 years can be presumed according to ISO 13849-1:2016 if the  Determination MTTFD values according to. EN ISO 13849-1:2015. 2. Compliance with safety principles, application notes. 3.

If the DC value was high enough for the PLr, then you are done with this part of the work. If not, you will need to go back to your design and add addi­tion­al dia­gnost­ic fea­tures so that you can either select a high­er cov­er­age from [1, Table E.1] or cal­cu­late a high­er value using [14].
