    Withdrawn Rationale:

    This guide serves as an aid to subcommittees in writing specifications and sampling procedures.

    Formerly under the jurisdiction of Committee D13 on Textiles, this guide was withdrawn in March 2009 because D13 no longer has the expertise to maintain and statistical standards are being maintained by committee E11.

    1. Scope

    1.1 This guide serves as an aid to subcommittees in writing specifications and sampling procedures.

    1.2 The guide explains how to estimate the contributions of the variability of lot sampling units, laboratory sampling units, and specimens to the variation of the test result of a sampling plan.

    1.3 The guide explains how to combine the estimates of the variability from the three sources to obtain an estimate of the variability of the sampling plan results.

    1.4 The guide is applicable to all sampling plans that produce variables data (Note 1). It is not applicable to plans that produce attribute data, since such plans do not take specimens in stages, but require that specimens be taken at random from all of the individual items in the lot. Note 0This guide is applicable to all sampling plans that produce variables data regardless of the kind of frequency distribution of these data, because no estimates are made of any probabilities.
