ASTM RR:C11-1001 PDF Download

The ASTM RR:C11-1001 standard is a set of guidelines for conducting physical tests on gypsum panel products. These products include materials such as gypsum board, gypsum sheathing, and gypsum base for veneer plaster. The purpose of this standard is to provide consistent testing methods that can be used by different laboratories to obtain reliable and comparable results.

The standard is divided into different sections, each specifying a particular test method for evaluating different properties of gypsum panel products. These properties may include dimensions, flexural strength, moisture content, nail-pull resistance, and core hardness, among others. The standard provides detailed instructions on sample preparation, test apparatus, and testing procedures to ensure accuracy and reproducibility of the results.

To ensure the precision of the test methods, an interlaboratory study was conducted for Method B specified in ASTM C0473-09. This study aimed to establish precision statements, which describe the degree of agreement between test results obtained by different laboratories using the same method. Precision statements provide information on the variability of the test results and are important for determining the reliability and comparability of the data generated by different labs.
