Overview of IEC 61508 - Design of electrical / electronic / programmable electronic safety - related systems
The aim of the international standard IEC 61508 is to provide a route whereby safety-related systems can be implemented using electrical or electronic or programmable electronic technology in such a way that an acceptable level of functional safety is achieved. The strategy of the standard is first to derive the safety requirements of the safety-related system from a hazard & risk analysis and ...
متن کاملUsing IEC 61508 to Guide the Investigation of Computer-Related Incidents and Accidents
Relatively few investigation techniques have been specifically developed to identify the causal factors that contribute to mishaps involving safety-critical computer systems. This is a significant omission because a number of factors distinguish this class of incidents from other mishaps. For example, the Rand report into NTSB investigation methods observed that the introduction of software con...

boron nitride semiconducting zigzag swcnt, $b_{cb}$$n_{cn}$$c_{1-cb-cn}$, as a potential candidate for making nanoelectronic devices was examined. in contrast to the previous dft calculations, wherein just one boron and nitrogen doping configuration have been considered, here for the average over all possible configurations, density of states (dos) was calculated in terms of boron and nitrogen ...
15 صفحه اولIntroduction to IEC 61508
Over the past 25 years there have been a number of initiatives worldwide to develop guidelines and standards to enable the safe exploitation of programmable electronic systems used for safety applications. In the context of industrial applications (to distinguish from aerospace and military applications) a major initiative has been focussed on IEC 61508 and this standard is emerging as a key in...
متن کاملProgrammable Electronic Safety Systems*
Traditionally safety systems intended for protecting personnel from electrical and radiation hazards at particle accelerator laboratories have made extensive use of electromechanical relays. These systems have the advantage of high reliability and allow the designer to easily implement failsafe circuits. Relay based systems are also typically simple to design, implement, and test. As systems, s...
