iec 61508 standard IEC Standard deals with the entire safety lifecycle of safety systems, from cradle to grave. It targets suppliers of safety systems, but is also applicable to some degree to suppliers of equipment used in those safety systems. There is often one national AB in each country.
IEC certification programs have been established by several global Certification Bodies. Each has defined their own scheme based upon IEC and other functional safety standards.

The scheme lists the referenced standards and specifies procedures which describes their test methods, surveillance audit policy, public documentation policies, and other specific aspects of their program.
This is such a key document to get right, we would recommend writing it with reference to iec 61508 standard sub-clause of Part 2 clause 7. Only use safety-related systems as iec 61508 standard last resort when the hazard and risk assessment indicate.
Once a SIL-rated system is specified, iec 61508 standard brings with it implications concerning the safety management system, competence of persons, demand rate analysis, modification control, proof testing regimes, and the like.
Component certification Manufacturers would do well to note the emphasis in the requirements of the standard in terms of certain items of documentation.

Once these documents are well defined and verified, they form a iec 61508 standard basis for the remainder of the project to continue. The key iec 61508 standard are: At the end of our study, we concluded: Manufacturers wisely have a gap-assessment of their development processes against the requirements of IEC undertaken for them as a first step to proceeding with formal certification.
Where certification efforts have failed, insufficient understanding and support for the project from senior management have ensued.
A set of guidelines for the development of vehicle based software was published in November MISRA C has gone on to become the de facto standard for embedded C programming in the majority of safety-related industries, and is also used to improve software quality even where safety is not the main consideration.
MISRA has also iec 61508 standard guidelines for the use of model based development.
What is IEC 61508?
It is intended to cover the development iec 61508 standard software for railway control and protection including communications, signaling and processing systems.
IEC Standard deals with the entire safety lifecycle of safety systems, from cradle iec 61508 standard grave. It targets suppliers of safety systems, but is also applicable to some degree to suppliers of equipment used in those safety systems.
