ASTM E2282-09

1.1 The purpose of this guide is to provide guidelines for identifying the elements that comprise the test result of a test method and to illustrate how these elements combine into the test result.

All test methods have an output in the form of a test result. This guide provides information on the construction of test results from more elemental measurements.

A well defined test result is necessary before any precision statements can be made about the test method.

Form and Style for ASTM Standards, Section A21, requires that every test method shall contain a statement regarding its precision, preferably as a result of an interlaboratory test program. Reporting of such studies is described in E 177, which illustrates the development of test results from observations and test determinations.

Precision statements for ASTM test methods are applicable to test results. They are not applicable to test determinations or observations, unless specifically and clearly indicated otherwise.
