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....
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...
Systems such as airbags, anti-lock brakes or power steering require an ASIL-D grade - the highest rigor applied to safety assurance - because the risks associated with their failure is the highest. In addition, all electrical and electronic systems must undergo a safety analysis, for example, ...
DIASYS Netmation, which was released in 2000, has been highly regarded for the high reliability of its control equipment, and its user-oriented operational monitoring and engineering tools. The solution is not just a great fit for thermal power plants; it also works as a control and monitoring...
What is a SIL Certification and What Does It Do? When installing a SIL certified level sensor, the installation is certified regarding safety and process. These are defined in various standards, such as IEC 61508, that cover functional safety of electrical, electronic and programmable safety relate...
