As the voice of the U. This practice is intended for use in determining the sample size required to axtm, with specified precision, such a measure of the quality of a lot or process either as an average value or as a fraction not conforming to a specified value. It can also be used to establish practical estimations of the various measures by experiment. Historical Version s – view previous versions of standard.
