Evaluation of Safety Parameters According to IEC Standards

Abstract

The article deals with different procedures for determining the safety integrity level and its applications. The purpose of this research was to evaluate the system and associate it with certain safety integrity level. In this article, we will use IEC 61508, IEC 61511 and IEC 62061 for comparison. The first standard is specified as the superior standard for all safety-critical systems. The second one acts as an extension of the superior standard in the field of functional safety. The last one is aimed at machinery safety.
