EN 50129 Safety Case

FuSa_Railway

The EN 50129 safety case is the structured and documented safety statement that the conditions for safety acceptance have been fulfilled. The safety case includes all safety-relevant aspects of the product life cycle. When creating the document, the challenge is therefore to present a wide range of information in a clear and comprehensible manner. EN 50129 supports you in this by providing a relatively detailed structure for the documentation.

In the following article, I will deal with the key factors relevant to practice for an EN 50129 compliant safety case. Read more

EN 50128 and EN 50657 support tools

FuSa_Railway

Chapter 6.7 of EN 50128 and EN 50657 support tools and languages defines requirements for software tools that are used in a safety-relevant development process. Project team members in safety projects discuss the content and meaning of this chapter again and again. The following article summarizes the essential requirements and derives a practical guide for use in the project. What EN 50128 and EN 50657 call Supporting Tools is often referred to as Tool Qualification.

EN 50128 configurable Systems – The solution?

FuSa_Railway

EN 50128 configurable Systems: Chapter 8 of EN 50128 specifies the requirements for systems that are configured by application data or application algorithms (EN 50128 configurable Systems). This blog summarizes the essential requirements of the standard and the practice-oriented challenges of software-configurable embedded systems.
At the first glance the configurability offers only advantages. The functional behavior of the entire system can be adjusted by simple and rapid changes in the application data to the desired behavior. The source code of the generic software is not to changed. A multiple reuse is possible thereby. If it is well done, even the unit tests should be reuseable, without any change. The EN 50128 also states that proven, generic software can be reused repeatedly in this way. These are important advantages. Read more

EN 50128 Functional Safety in the railway industry

FuSa_Railway

The EN 50128 Functional Safety standard describes together with the EN 50126 and EN 50129 the functional safety in the railway industry. These standards implement the IEC61508 for this industry.
The peculiarity of the rail industry with regard to functional safety is that the systems are to be certified by an governmental authority (in Germany the federal railway authority), before they are allowed to be placed into a railway system. So, the manufacturer must provide proof of compliance with the functional safety standards already during the development of the product. In this point the aviation and rail industry are very similar.
