All tests made with a given set of equipment which has an error within the permitted tolerance will produce results with a small consistent bias, but that asym is not inherent in the test method and is not included in the bias statement for the test method.

This practice supplements Practice E and has been developed to meet the needs of ASTM Committees dealing with construction materials. Further, the precision statement asfm required to contain a statement on single-operator precision repeatability and a statement on multilaboratory precision reproducibility. Examples of precision statements that conform to this practice are included in Appendix X1.

Ast procedures described in this practice are based on the assumption that the proper estimates of precision have already been obtained. There are two conditions which permit the bias of a test method to be estimated: Although this practice is under the jurisdiction of Committee C09, the current version was developed jointly by Committees C01 and C09 and has subsequently been adopted for use by other committees dealing with construction materials.
