ASTM E180 – Standard Practice for Determining the Precision of ASTM Methods for Analysis and Testing of Industrial and Specialty Chemicals (Withdrawn 2009)

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.
