SIS & Functional Safety

SIS & Functional Safety – We understand the pace of technology change continues to accelerate with regards to functional safety certification and proof of competence. In fact, the IEC 61508 and IEC61511 set of standards are increasingly being sought by the UK regulatory body and by end-users as a means of minimising risk to people and property. The standards and supporting ACOPs provide guidance on demonstrating best practice in the field of functional safety within the process industry.

Manufacturing and operating companies within the process industry sector are legally obliged to ensure safety in the workplace and safety instrumented systems must be able to demonstrate they are adequate to provide a safety level that has been declared in any safety case.

Conformity to IEC 65108 or IEC 61511 is a proven way to demonstrate the protection measures for safety instrumented systems are able to provide the declared reduction in risk. IEC 61508 is the generic standard for Functional safety of electrical/electronic/programmable electronic safety-related systems and IEC 61511 is the standard for safety instrumented systems for the process industry sector.
