Higher level classes2#
Declared properties5#
discrete level (one out of a possible three) for describing the capability to perform a safety function where safety integrity level three has the highest level of safety integrity and safety integrity level one has the lowest
average frequency of dangerous failure of a safety-related control system to perform a specified safety function over a given period of time
mean number of operating cycles at which ten percent of the components fail dangerously
expectation of the mean time to dangerous failure
time interval between tests performed to detect dangerous hidden failures in a safety-related system
