If the process is not in a state of statistical control, the result will not have predictive value for immediate future production. This practice will e1222 indicate the sample size required to estimate the average value of some property or the fraction of nonconforming items produced by a production process during the time interval covered by the random sample.

Already Subscribed to this document. The examples are not binding on products or test methods treated. If so, an estimate of the average value of that characteristic or of the fraction of the observed values that do not conform to a specification for that characteristic becomes a measure of quality with respect to that characteristic.
