ASTM E2105

ASTM E2105 is the ASTM standard for general techniques of thermogravimetric analysis (TGA) coupled with infrared analysis (TGA/IR). It provides a technical framework for combining mass-change measurement with infrared detection so users can better observe how materials behave during heating or decomposition. This makes the standard useful for producing more consistent, interpretable results when thermal analysis data are needed for evaluation, comparison, or quality-related decisions.

ASTM E2105 standard overview

The official title, Standard Practice for General Techniques of Thermogravimetric Analysis (TGA) Coupled With Infrared Analysis (TGA/IR), indicates a practice focused on method technique rather than a narrowly defined material specification. ASTM E2105 is intended to guide how TGA and infrared analysis are paired so the resulting data are collected in a controlled, comparable way. It is especially relevant when the thermal response of a sample and the infrared information from evolved products both matter to the test outcome.

Where is ASTM E2105 used?

This practice is commonly used in laboratories that perform thermal analysis and need to connect weight-loss behavior with infrared observation of evolved gases or other thermal products. It may support material evaluation, failure analysis, formulation work, and other testing workflows where understanding thermal decomposition is important. ASTM E2105 is most useful in settings that rely on TGA/IR instrumentation and need a consistent approach for generating and reviewing results.

Practical importance of ASTM E2105

In practice, ASTM E2105 helps improve consistency in how TGA/IR testing is carried out and interpreted. That can support better comparison between runs, clearer communication of results, and more reliable procurement or quality control decisions. For organizations that depend on thermal analysis data, using a recognized ASTM standard may reduce ambiguity in test procedures and help align laboratory work with established technical practice. ASTM E2105 is therefore valuable where repeatability and defensible reporting matter.
