❌
: It reduces the complex calculations involving approximately 70 parameters in the full standard to a more manageable subset.
The is a software tool originally developed to assist in calculating lightning-related risks as defined by the IEC 62305-2 standard. It was first introduced as an "informative annex" (Annex J) to the 2006 edition of the standard to provide a more accessible, entry-level alternative to complex manual calculations. Key Purpose and Scope simplified iec risk assessment calculator sirac
) for a safety function to mitigate a specific risk. It breaks down the qualitative and semi-quantitative assessment methodologies mandated by the standard into an easy-to-follow, step-by-step calculator. Why Use a Simplified IEC Risk Assessment Calculator?
: A definitive "Yes/No" statement on whether a protection system is mandatory. : Recommendations for Class I, II, III, or IV protection based on the required efficiency. Surge Protection (SPD) ❌ : It reduces the complex calculations involving
SIRAC was designed as a streamlined alternative to the full, often overwhelming, risk assessment process. While the complete IEC 62305-2 standard involves dozens of intricate variables, SIRAC focuses on a limited subset of parameters specifically for relatively simple, single-zone structures.
