Reliability

Designing a safety provision the most important starting point is: How reliable is the safety provision.

In the last decade most particularly the process industry developed a methodology for safety instrumented systems, which is applicable almost worldwide and which is used to test if safety provisions are adequate.

The methodology is captured in NEN-EN-IEC 61508, NEN-EN-IEC 61511 (process industry specific) and NEN-EN-IEC 62061 (machine safety specific). )

As from 31 December 2005 the EN-IEC 62061 is harmonised in the machine directive. Protecs is design with these NEN frameworks in mind.
