This edition constitutes a technical revision. It provides iec 61508-1 that are applicable to the system level design of all types of machinery safety-related electrical control systems and also for the design of non-complex subsystems or devices.

We use cookies to make our website easier to use and iec 61508-1 better understand your needs. A risk assessment effort yields a target SIL, which thus becomes a requirement for the final system. We operate in countries and are the number one certification body in the UK and US. A major objective of this standard is to facilitate the development of product and application sector international standards by iec 61508-1 technical committees responsible for the product or application sector.

Iec 61508-1 safety integrity level SIL provides a target to attain in regards to a system’s development. The faster, easier way to work with standards.

It then defines the overall safety life cycle requirements — such as hazard and risk analysis, maintenance planning, and verification — before looking at the best practice assessments of iec 61508-1 safety. In some higher SIL level applications, the software code coverage requirement is much tougher and an MCDC code coverage criterion is used iec 61508-1 than simple branch coverage.

IEC is a technical standard which sets out iec 61508-1 in the engineering of systems that ensure the safety of an industrial process through the use of instrumentation.
