Max OC(LTPD) - Maximum Probability of Acceptance at LTPD

For sampling plans with varying protection, there are three OC curves: stationary OC Curve, maximum OC Curve and the minimum OC Curve.  The LTPD is determined using the stationary OC curve.  The maximum probability of acceptance at the LTPD is determined using the maximum OC Curve, denoted Max OC(p).  The default probability of acceptance at the LTPD is 0.1.  However, the actual probability of acceptance varies and can be as great as Max OC(LTPD).  The Max OC(LTPD) along with Min OC(AQL) are used to summarize the behavior of the sampling plan as the protection varies.
