ASTM RR:C09-1036 PDF Download

ASTM RR:C09-1036 is a research report that focuses on the precision and bias statement for ASTM C1550, which is a test method for determining the flexural toughness of fiber reinforced concrete using centrally loaded round panels. The report describes an interlaboratory study conducted to establish the precision and bias statement for this test method.

The study involved the participation of six testing machines and operators who performed tests on six replicate panel specimens for each of the six fiber reinforced concrete mixtures. These mixtures were specifically designed to provide varying levels of peak load and energy absorption.

The purpose of the study was to assess the repeatability and reproducibility of the test results across different laboratories and operators. By testing multiple samples and involving multiple laboratories, the study aimed to determine the level of agreement between test results and establish the precision and bias statement for the test method.
