Scope1.1 This practice covers simple methods for calculating howmany units to include in a random sample in order to estimatewith a specified precision, a measure of quality for all the unitsof a lot of material, or produced by a process.

This practice willclearly indicate the sample size required to estimate theaverage value of some property or the fraction of nonconform-ing items produced by a production process during the timeinterval covered by the random sample. If the process is not ina state of statistical control, the result will not have predictivevalue for immediate (future) production. The practice treats thecommon situation where the sampling units can be consideredto exhibit a single (overall) source of variability; it does nottreat multi-level sources of variability.2.
