Abstract

ASTM test methods are used as the basis for on-site inspections performed by the Cement and Concrete Reference Laboratory (CCRL) in construction material testing laboratories. The equipment and test procedures employed by the laboratory are examined, and deviations from the requirements of the test method are reported. With the aid of a computer program, the results from these inspections are summarized. The computer output includes the percentage of conformance, a description of the deviations, and the number of times each deviation was noted. These summaries are useful to ASTM subcommittees with jurisdiction over the various summarized test methods. A description of the CCRL programs and an explanation of the summaries of results are included.
