IEC provides requirements and recommendations for the instrumentation and control for systems important to safety of nuclear power plants. Customers who bought this product ieec bought BS EN In some higher SIL level applications, the software code coverage requirement is much tougher and an MCDC code coverage criterion is used rather than simple branch coverage.

Systematic Capability SC which is a measure of design quality. List of International Electrotechnical Commission standards. IEC is an international standard published by the International Electrotechnical Commission idc of methods on how to apply, design, deploy and maintain automatic protection systems called safety-related systems. This publication is of high relevance for Smart Grid. An engineering process called the safety life cycle is defined based on best practices in order to discover and eliminate design errors and omissions.

One of these, for the qualitative analysis of hazards, is a framework based on 6 categories of likelihood of occurrence and 4 of consequence.

It is being widely adopted by the major car manufacturers. The main requirement in Unit Testing is to ensure that the software is fully tested at the function level and that all possible branches and paths are taken through the software.

There is often one national AB in each country. Views Read Edit View history. Search all products by. Each device in the design has an SC rating. 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.


The standard requires that hazard and risk assessment be carried out for bespoke systems: Architecture Constraints which are minimum levels of safety redundancy presented via two alternative methods – Route 1h and Route 2h.

It defines functional safety as: For any given design the achieved SIL level is evaluated by three measures:. The safety integrity level SIL provides a target to attain for ie safety function. We use cookies to make our website easier to use and to better understand your needs. Annex B gives an example technique for calculating the probabilities of hardware failure and should be read in conjunction with 7.

Certification Bodies are accredited to perform the auditing, assessment, and testing work by an Accreditation Body AB. Errors introduced anywhere from the initial concept, 6508-6 analysis, specification, design, installation, maintenance and through to disposal could undermine even the most reliable protection.

Annex A gives a brief overview of the requirements of IEC and IEC and sets out the functional steps in their application. Before the launch of ISOthe development of software for safety related automotive systems was predominantly covered by the Motor Industry Software Reliability Association guidelines.

Annex D gives a methodology for quantifying the effect of hardware-related common cause failures on the probability of failure. Annex E gives worked examples of the application of the software safety integrity tables specified in Annex A of IEC for safety integrity levels 2 and 3.


It indicates the general requirements for systems that contain conventional hardwired equipment, computer-based equipment or a combination of both types of equipment. Changes made in this 2nd edition are highlighted and commented by a leading world expert. Take the smart route to manage medical device compliance.

This article relies largely or entirely on a single source.

Each has defined their own scheme based kec IEC and other functional safety standards. 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.

Annex D gives a methodology for quantifying the effect of hardware-related common cause failures on the probability of failure.

The risk is a function of frequency or likelihood of the hazardous event and the event consequence severity.

Relevant discussion may be found on the talk page. Requirement for SC are presented in a series of tables in Part 2 and Part 3.

Software written in accordance with IEC may need to be unit testeddepending up on the SIL level it needs to achieve. This second edition cancels and replaces the first 615086- published in IEC specifies techniques that should be used for each phase of the life-cycle.

Annex C gives a worked example of calculateing diagnostic coverage and should be read in conjunction with BS EN By using this site, you agree to the Terms of Use and Privacy Policy. The standard has two fundamental principles: It has been subject to a thorough review and incorporates many comments received at the various revision stages.
