ASTM RR:C09-1044 PDF Download

The ASTM RR:C09-1044 standard focuses on a specific test method called C567. This standard details the process by which the density of structural lightweight concrete can be determined.

To establish a precision statement for this test method, an interlaboratory study was conducted involving eight different laboratories. These laboratories tested two samples using the test method C567. The purpose of this study was to analyze and evaluate the precision of the test method and ensure accurate and reliable results.

By conducting the interlaboratory study, ASTM aims to determine the level of agreement between different laboratories and assess the repeatability and reproducibility of the test method. This allows for the establishment of a precision statement, which summarizes the level of variability expected when performing the density determination of structural lightweight concrete using this particular test method.
