ASTM C670 – 15

The interlaboratory study provides the necessary statistical values to write the precision and bias statements. This practice supplements Practice E and has been developed to meet the needs of ASTM Committees dealing with construction materials. In any test method, tolerances are placed on the accuracy of measuring equipment.

Further, the precision statement is required to contain a statement on single-operator precision repeatability and a statement on multilaboratory precision reproducibility.
