Now, on stage left is ISO 13849-1. This standard uses a “quantitative” statistical analysis approach to actually engineer the safety-related parts of the control system (SRP/CS). In other words, a probabilistic determination regarding the reliability of components, devices, software, and …

Positive assessment by IFA. 1 channel, 100-fold test of SF before need, 0 failure safety between test phases In case of pressure drop, the non-return valves 1V2 and 1V5 avoid exhausting -> cylinder is kept in position. iso 13849-1（机械安全 - 控制系统的安全相关部分 - 设计通则）为国际标准，修订于2006 年。其修订背景是：半导体器件（如 晶体管和mos-fet）已在构成控制系统的安全相关部分的安全机械中投入应用，这代表了控制方法由硬布线控制方式到软件控制方 式的转变。 ISO 13849-1:2015 provides safety requirements and guidance on the principles for the design and integration of safety-related parts of control systems (SRP/CS), including the design of software. Within the field of machinery safety, standards relating to the safety related parts of the control system have been a topic of concern for some time. EN 954 EN ISO 13849-1 goes beyond the qualitative approach of EN 954-1 to include a quantitative assessment of the safety functions. Performance levels (PL) are defined in EN ISO 13849-1 to classify different safety-related capacities into their respective categories.

The architecture of different hardware and software (categories);; Possible diagnostic coverage;; Component reliability (MTTFd);; Common causes of failure.

Note that the Performance Levels (PL) under ISO 13849-1 correspond to certain PFH D ranges — so can be cross-referenced to SIL levels In Categories 1, 2, 3 and 4, safety principles which are well-tried must also be applied. Information on these aspects can be found in EN ISO 13849-2. Quantitative requirements the observance of which is checked by SISTEMA also apply to the Categories. The procedure described here is geared to the application of EN ISO 13849-1 and its "desig- Circuit examples ISO 13849.

EN ISO 13849-1 is based on the familiar categories from EN 954-1:1996. It examines complete safety functions, including all the components invol- ved in their design. EN ISO 13849-1 goes beyond the qualitative approach of EN 954-1 to include a quantitative assessment of the safety functions.

It is classification of the safety-related parts of a control system in respect of their resistance to faults and their subsequent behavior in the fault condition, and which is achieved by the structural arrangement of the parts and/or by their reliability. ISO 13849-1:2006 2018-01-09 · The ISO 13849-1 safety standard from the International Organization for Standardization (ISO) is a universal standard meant to help build safety systems in machinery with sufficient reliability. For machine builders and users, ISO 13849-1 is a guide for safe operations. The ISO 13849-1 methodology uses the category of circuit structure/architecture, mean time to dangerous failure (MTTFd), number of cycles with which 10 percent of components have a failure to danger (B10d), diagnostic coverage (DC) and common cause failure (CCF) to determine the PL of a control system. This standard BS EN ISO 13849-1:2015 Safety of machinery.

In categories B and 1, the resistance to faults is achieved primarily by the selection and use of suitable components. Category 1 has a greater resistance than category B because of the use of basic and well-tried principles, as well as well-tried components, wich are … stipulated Performance Level PL d with Category 3 according to ISO 13849-1 or SIL due to IEC 62061). Possible constructive measures (high protection against failure) can be like this: • Protection against self loosening (e.g. welding, riveting) Amendment of EN ISO 13849-1 (October 2015) Page 4 of 9 • In Categories 2 and 3: adequate measures against CCF, and for each component DC at least "low".

Categories were used also in the earlier machinery safety standard EN 954-1:1996. The report describes in detail the meaning of each category and also gives an example of a category 2 safety function. EN ISO 13849-1: Performance Level (PL) Ju högre risk desto högre är kraven på styrsystemen.

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.

It examines complete safety functions, including all the components invol- ved in their design. EN ISO 13849-1 goes beyond the qualitative approach of EN 954-1 to include a quantitative assessment of the safety functions.
