Developed by Subcommittee: D13.93
WITHDRAWN, NO REPLACEMENT
This guide serves as an aid to subcommittees writing and maintaining test methods. It helps to (1) determine if it is possible to reduce test variability, and, if so, provide a systematic approach to the reduction.
This guide is being withdrawn with no replacement because D13 no longer has the expertise to maintain and statistical standards are being maintained by committee E11.
Formerly under the jurisdiction of Committee D13 on Textiles, this guide was withdrawn in July 2008.
