5.1 The test method calibrates or demonstrates conformity of the torque signal of a rheometer at ambient temperature.5.2 A calibration factor thus determined may be used to obtain correct torque values.5.3 This test method may be used in research, development, specification acceptance, and quality control or assurance.1.1 This test method describes the calibration or performance conformance for the torque signal generated by commercial or custom-built rheometers. The specific range of the test depends upon the torque range of the rheometer.1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
