ASTM Committee to develop proposed bias equivalency standard.
Press Release Summary:
Jun 07, 2012 - In many testing laboratories, it can be necessary to qualify new test method, instrument, or lab itself with respect to one or more performance characteristics. ASTM WK37659, Guide for Testing for Bias Equivalency in the Laboratory, will provide guidance on proper design of equivalence studies, including proper numbers of tests required, assistance in deciding what constitutes sufficient agreement, and selection of proper statistical test for evaluating data.

Proposed Bias Equivalency Standard Being Developed by ASTM Quality and Statistics Committee
Press release date: Jun 04, 2012
ASTM WK37659, Guide for Testing for Bias Equivalency in the Laboratory, is being developed by Subcommittee E11.20 on Test Method Evaluation and Quality Control, part of ASTM International Committee E11 on Quality and Statistics.
According to Thomas Murphy, independent statistical consultant, T.D. Murphy Statistical Consulting LLC, and E11.20 chairman, anyone concerned with the development or application of a test method would be a potential user of ASTM WK37659.
"This proposed standard would apply to most, if not all ASTM committees having test methods," Murphy says. "Guidance will be given on the proper design of equivalence studies, including proper numbers of tests required, assistance in deciding what constitutes sufficient agreement, and selection of the proper statistical test for evaluating the data. Methodologies will be given for determining equivalence at a single level of a property or over a range of property levels."
Murphy says that the task group developing ASTM WK37659 is seeking participants who have knowledge of and experience with bias equivalency and who are interested in taking an active role in the writing and final editing of the proposed standard. In addition, the task group is interested in obtaining data sets from previously conducted equivalence testing since actual examples will be included to illustrate the methods covered in ASTM WK37659.
