Influence of diagnostics errors on safety: Indicators and requirements

In article questions of intersection of indices of technical diagnostics and the functional safety are considered. The relevant standards on diagnostics (IEC 60706-5-2007) and the functional safety (IEC 61508-4:2010) determining indices of a completeness and reliability of diagnosing, a share of safe failures and spanning by diagnostics are defined. Requirements to indices of the functional safety for achievement of the necessary level of a completeness of safety of electronic systems are selected. Influence of errors of system of diagnosing on indices of the functional safety is considered that allows to specify their assessment before carrying out evaluation tests.
