ABSTRACT
There are three principal financial methods for calculating the propriety of choosing to perform 100% inspection on an item of production. In each method, the answer may come out yes or no. Before going further, it must be stated that the inspection method itself must be nondestructive. Otherwise, one must revert to batch certification by statistical methods applied to destructive tests, that is, to sampling. Sampling is well known and will not be dealt with in this book. Nondestructive testing (NDT) methods and correlations will be reviewed in Chapter 8.
