Omfang

The purpose of this practice is to present concepts necessary to the understanding of the terms “precision” and “bias” as used in quantitative test methods. This practice also describes methods of expressing precision and bias and, in a final section, gives examples of how statements on precision and bias may be written for ASTM test methods. A statement of precision allows potential users of a test method to assess in general terms the test method’s usefulness with respect to variability in proposed applications.In this practice only quantitative test methods that produce numerical results are considered. Also, the word “material” is used to mean material, product, system or service; the word “property” is used herein to mean that a quantitative test result can be obtained that describes a characteristic or a quality, or some other aspect of the material; and “test method” refers to both the document and the procedure described therein for obtaining a quantitative test result for one property.
