The use of realistic and application appropriate failure rate data has a significant impact on the validity of SIL verification calculations. Unfortunately there is often conflicting or incomplete information readily available to perform this task.

Low Bound
3/12
High Bound
11/12

Determining if data is suitable for use is a critical first step. The SILSafeData.com website is a listing of upper and lower bounds for various devices commonly used in safety instrumented functions. These bounds were derived from statistical analysis of FMEDA results which represent design variations and application variations in combination with extensive comparisons with realistic field failure data. exida calls this technique “Predictive Analytics.”

SILSafe Data

The upper bound and lower bound dangerous failure rate data in SILSafeData is presented to perform quick comparisons with any piece of data. If the dangerous failure rate provided is not within the limits, further analysis and justification is warranted before using the provided data.
