    Abstract

    Test precision statements are frequently used in evaluating the quality of test results used to judge the acceptibility of materials. This paper provides an overview of the activities of the Materials Reference Laboratories at the National Bureau of Standards and demonstrates how data from the reference sample programs can be analyzed to formulate precision estimates that can then be used to develop precision statements for ASTM test methods. Precision estimates derived from the analysis of CCRL portland, blended, and masonry reference sample data are presented for selected cement tests.
