An interlaboratory “round robin” test study was conducted for the calibration method developed by ASTM Task Group E37.01.12, which was described in Part I of this paper. The interlaboratory test protocol was consistent with the requirements outlined in ASTM E 691, Practice for Conducting an Interlaboratory Test Program to Determine the Precision of Test Methods. The results obtained by 10 participating laboratories were used to prepare a precision and bias statement for ASTM E 1363, Test Method for Temperature Calibration of Thermomechanical Analysers. Statistical treatment of the data yielded at the 95% confidence level a repeatability limit r = 1.43904°C, a reproducibility limit R = 4.11475°C, and a bias of 0.0137°C.
