Developed by Subcommittee: E15.01
WITHDRAWN, NO REPLACEMENT
This practice establishes uniform standards for expressing the precision and bias of test methods for industrial and specialty chemicals.
This practice is being withdrawn because ASTM has an ILS program that E15 has used and will continue to use. Also, among other supporting factors, E180 goes through a lot of hand calculations when there are available statistical packages to do these analyses. This makes this practice appear overly complex and may discourage the use of such studies within the committee. With the ASTM ILS program available, E180 could be retired to IHS (ASTM and other standards associations' archive facility) and would be available for a fee.
Formerly under the jurisdiction of Committee E15 on Idustrial and Specialty Chemicals and the direct responsibility of Subcommittee E15.01 on General Standards, this practice was withdrawn in October 2009 with no replacement.
1.1 This practice establishes uniform standards for expressing the precision and bias of test methods for industrial and specialty chemicals. It includes an abridged procedure for developing this information, based on the simplest elements of statistical analysis. There is no intent to restrict qualified groups in their use of other techniques.
1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
1.3 In this practice, the vocabulary and guidelines for calculation and interpretation of statistical data according to the ISO are followed as closely as possible. Particular reference is made to ISO 5725, Parts 1 to 6.
