which have emerged as key international standards.This paper considers some of the key features of IEC 61508 (IEC 2000), which has now been available for over ten years, and indicates the main changes that have been incorporated into the new Edition 2 (IEC 2010a), published in April 2010....
However, given the high reliability required for most railway applications, another fundamental standard is to be considered: IEC 61508 – An international standard published by the International Electrotechnical Commission. IEC 61508 Regulations IEC 61508 provides functional safety standards for the ...
As an adaptation of the IEC 61508 standard, theISO 26262 standardspecifies recommendations to ensure functional safety throughout the product development cycle—at the system, hardware, and software levels. TheASIL classificationis a key component of theISO 26262 standardcompliance. Mo...
While IEC 61508 provides the general framework, for gas detection equipment the relevant standard is EN50402:2005+A1:2008Electrical apparatus for the detection and measurement of combustible or toxic gases or vapours or of Oxygen. Requirements on the functional safety of fixed gas detection systems. ...
It should be noted that IEC 61508 limits the risk reductions which can be claimed for a safety related E/E/PES which operated in low demand mode or continuous mode to no better than 10-6and 10-9respectively for SIL4. The requirement is more demanding for subsystems which do not have we...
Functional Safety, as defined by IEC standard 61508, is the safety that control systems provide to an overall process or plant. The concept of Functional Safety was developed in response to the growing need for improved confidence in safety systems. Major accidents around the world, as well as...
In 2024, we stopped providing SIL-compatible systems that have obtained certification under the functional safety standard (IEC61508) due to difficulties in obtaining electronic components. Since then, we have only been able to support the maintenance of delivered products. ...
