    Abstract - (Show below) - (Hide below)

    Describes: a) technical guidance in Safety Integrity Level (SIL) Analysis; b) ways to implement Safety Instrumented Functions (SIF) to achieve a specified SIL; c) failure rates and failure modes of SIF components; d) diagnostics, diagnostic coverage, covert faults, intervals, redundancy of SIF components; and e) tool(s) for SIL verification of SIF.
