# §42.141. Obtaining Operating Characteristic (OC) curve information for skip lot sampling and inspection.


The Operating Characteristic (OC) curve information (probability of acceptance) for skip lot sampling and inspection procedures described in [§ 42.121](/cfr/7/42.121.md) is easily obtained from the single curve in [§ 42.142](/cfr/7/42.142.md). The procedure for using the curve in [§ 42.142](/cfr/7/42.142.md) is as follows:

- (a) Select any sampling plan for normal condition of container inspection from Table I or Table I-A of [§ 42.109](/cfr/7/42.109.md).
- (b) For a given Quality of Submitted Lots, 100p, find the Percent of Lots Expected to be Accepted, Pa from the respective OC curve in [§ 42.140](/cfr/7/42.140.md).
- (c) Refer to [§ 42.142](/cfr/7/42.142.md) with this Percent of Lots Expected to be Accepted, Pa, and read the new Percent of Lots Expected to be Accepted, Pas, which results when using these skip lot procedures.
