Abstract
Risks are categorized, e.g. to prioritize them and to select safety systems and devices with adequate safety properties. A wrong functional safety level estimation causes either exaggerated costs or an increase in the risk of accidents. The risk assessment for estimating functional safety requirements was researched and the results are presented at the paper. A round robin test was conducted to compare and check how well the methods matched each other. The assessors estimated the parameters of the risks and assigned the required SIL (Safety Integrity Level according to IEC 62061) and PL (Performance Level according to ISO 13849-1). The study shows that in most cases the results correspond to each other, though there are some exceptions. The IEC 62061 method rarely results in SIL 1 but instead in SIL 0 or SIL 2.
