1.1 This test method provides procedures for validating temperature and length change measurements of thermomechanical analyzers ( TMA ) and analytical methods based upon the measurement of temperature and length change. Performance parameters include temperature repeatability, linearity, and bias; and dimension change repeatability, detection limit, quantitation limit, linearity, and bias. 1.2 Validation of apparatus performance and analytical methods is a necessary requirement for quality initiatives. Results may also be used for legal purposes. 1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.4 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. 1.5 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. ====== Significance And Use ====== 5.1 This test method may be used to determine and validate the performance of a particular thermomechanical analyzer apparatus. 5.2 This test method may be used to determine and validate the performance of a particular method based upon thermomechanical analyzer temperature or length change measurements. 5.3 This test method may be used to determine the repeatability of a particular apparatus, operator, or laboratory. 5.4 This test method may be used for specification and regulatory compliance purposes.
