ASTM E2402-19

5.1 This test method may be used to validate the performance of a specific thermogravimetric analyzer.

5.2 This test method may be used to validate the performance of a specific method based upon a thermogravimetry mass loss or residue measurement.

5.3 This test method may be used to determine the repeatability of a specific apparatus, operator, or laboratory.

5.4 This test method may be used for specification and regulatory compliance purposes.

1.1 This test method provides procedures for validating mass loss, residue, and temperature measurements by thermogravimetric analyzers (TGAs) and analytical methods based upon the measurement of mass loss or residue content or temperature. Performance parameters determined include mass loss, residue, and temperature repeatability (precision), detection limit, quantitation limit, linearity, and bias.

1.2 Validation of apparatus performance and analytical methods is requested or required for quality initiatives or where results may 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.
