1 Operating characteristic curve defined by producer's
risk (PR) and consumer's risk (CR)
2 Operating characteristic curve defined by acceptable
quality level (AQL) and limiting quality (LQ)
3 OC curves: Four sampling plans for AQL 1,5%
non-conforming, normal inspection, single sampling
4 Normal distribution
5 Distribution with large positive skewness
6 Comparison of operating characteristic curves for
single, double, multiple and sequential sampling
plans (code letter L, AQL 0,65%
7 Comparison of average sample sizes for single,
double, multiple and sequential sampling
(for acceptance plans of figure 6)

production is continuous and run length exceeds 10
lots of original inspection

production is not continuous or run is 10 lots or
fewer
