Performance verification or calibration is essential to the accurate determination of quantitative dimension change measurements.

This test method may be used for instrument performance validation, regulatory compliance, research and development and quality assurance purposes.

1. Scope

1.1 This test method describes calibration of the length change (deflection) measurement or thermal expansion of thermomechanical analyzers (TMA) within the temperature range from -150 to 1000 °C using the thermal expansion of a suitable reference material.

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 test method differs from ISO standard 11359-1 by providing an alternative calibration procedure.

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 whoever uses this standard to consult and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
