Significance and Use
This method may be used to validate the performance of a specific TGA apparatus.
This method may be used to validate the performance of a specific method based upon a TGA mass loss or residue measurement.
This method may be used to determine the repeatability of a specific apparatus, operator or laboratory.
This method may be used for specification and regulatory compliance purposes.
1. Scope
1.1 This method provides procedures for validating mass loss and residue measurements by thermogravimetric analyzers (TGA) and analytical methods based upon the measurement of mass loss or residue content. Performance parameters determined include mass loss and residue 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 There is no ISO standard equivalent to this method.
1.5 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 regulatory limitations prior to use.
