Standard Test Method for Mass Loss and Residue Measurement Validation of Thermogravimetric Analyzers

Fecha:
2019-09-24 /Historical
Superseeded by:
Significance and Use:

5.1 This test method may be used to validate the performance of a specific TGA apparatus.

5.2 This test method may be used to validate the performance of a specific method based upon a TGA 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.

Scope:

1.1 This test 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 test 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.6 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.
