    Withdrawn Rationale:

    This practice provides a procedure for evaluating and comparing test methods under controlled conditions using the same materials tested during the same time span. The practice describes how to obtain and compare estimates on precision, sensitivity, and bias.

    This practice is being withdrawn with no replacement because D13 no longer has the expertise to maintain and statistical standards are being maintained by committee E11.

    Formerly under the jurisdiction of Committee D13 on Textiles, this practice was withdrawn in July 2008.
