Developed by Subcommittee: D13.93
WITHDRAWN, NO REPLACEMENT
This guide is intended to assist laboratories in maintaining precision and controlling bias in testing.
Formerly under the jurisdiction of Committee D13 on Textiles, , this guide was withdrawn in March 2009 because D13 no longer has the expertise to maintain and statistical standards are being maintained by committee E11.
1.1 This guide is intended to assist laboratories in maintaining precision and controlling bias in testing. It includes statistical procedures for detecting lack of control, changes in calibration constants, and in operator technique. Suggestions are given for the correction of some out of control situations.
1.2 This guide includes the following topics:
|Significance and Use||4|
|Test Performance Control||6|
|Calibration Control||Annex A1|
|Test Performance Control||Annex A2|
1.3 This standard does not give all of the details for preparing statistical quality control charts or the statistical tests used to interpret them, but such information may be found easily in a number of publications.
