What is Systematic Capability? Systematic capability (SC) is a measure of the confidence that a safety-related element (hardware or software) meets the requirements of its specified Safety Integrity Level (SIL)
In the world of software testing, black-box testing stands out as one of the most widely used and essential methods. It is a test design approach where the system under
Safe failure fraction is an arbitrary metric used within IEC 61508 (and other guidance) in order to set architectural rules (or constraints). This is a metric based on diagnostic coverage.
Understanding Risk Receptors: Safeguarding People, Environment, and Assets In process safety, the concept of a risk receptor plays a pivotal role in identifying and mitigating potential hazards. A risk receptor
Understanding Mission Time in Reliability Engineering: A Key to System Reliability In reliability engineering, mission time refers to the period during which a system, component, or device is expected to
Modes of Operation of a SIF The demand mode of a Safety Instrumented Function (SIF) refers to the operational mode in which the SIF is activated only when a specific
Meaning of “On-Stream Factor” for Process Plants The on-stream factor or on-stream time is a key performance parameter used in the process industries (e.g., oil refining, petrochemicals, power plants) to measure the
Step 1: Application Program Safety Requirements Objective: To specify application program safety requirements for each SIS necessary to implement the required SIF. To specify the requirements for the application program
The Safety Instrumented System Safety Lifecycle defines the necessary activities involved in the implementation of SIF occurring during a period of time that starts at the concept phase of a
