This standard provides procedures for validating mass loss and residue measurements by thermogravimetric analyzers (TGA) and analytical methods based upon the measurement of mass loss and residue. This standard is applicable to the validation of performance parameters of the thermogravimetric analyzer, including mass loss and residue repeatability (precision), detection limit, quantitative limit, linearity, bias, technical description and regulatory compliance. 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 and health practices and determine the applicability of these practices prior to use.
