This parameter defines the potential consequence of the hazardous event if it occurs.
IEC 62061 allows "fault exclusions" (e.g., we assume a bolt won't unscrew itself). A calculator cannot assume this for you. You must manually document exclusions, or the calculator's output is invalid. iec risk assessment calculator
By multiplying these factors, the calculator outputs a or a required SIL level (1, 2, or 3) . This parameter defines the potential consequence of the
Rooted in the international standards IEC 61508 and IEC 62061, this methodology provides a structured, mathematical approach to determining the necessary safety integrity levels for machinery. This article serves as your definitive guide to understanding, using, and mastering the IEC risk assessment calculator to ensure compliance, protect assets, and, most importantly, save lives. You must manually document exclusions, or the calculator's
The calculator automates the "risk graph" or "risk parameters" method. It helps you convert real-world hazards into a numeric and, crucially, tells you what Performance Level (PLr) or Safety Integrity Level (SIL) your safety system needs to achieve.
