Partial testing is sometimes used as a supplement to proof testing to improve the reliability of safety‐instrumented systems (SISs) in low‐demand mode of operation. This paper studies the effect of partial testing on SIS reliability. Simplified formulas are developed to include both partial and proof testing in the calculation of the average probability of failure on demand (PFD
