Comprehensive Guide to ASTM E968 Thermogravimetric Analysis (TGA) of Materials Laboratory Testing Service
Standard-Related Information
ASTM E968 is a standard test method for the determination of thermal stability of materials using thermogravimetry (TG). The test measures the mass loss or gain of a sample as it is heated at a controlled rate, typically in an inert atmosphere. This information is critical in understanding the thermal behavior of materials, which can be used to predict their performance and safety under various conditions.
The standard is developed by ASTM International, a global standards organization that sets industry-wide testing and evaluation methods for materials, products, and systems. The development of standards involves a collaborative effort between experts from industry, academia, and government agencies. These standards are continuously reviewed and updated to reflect changes in technology, regulations, and scientific understanding.
Relevant Standards
International and National Standards
The international standards for thermogravimetry are developed by organizations such as ASTM International, ISO, and IEC. These standards are widely adopted across different countries and industries. In addition to the above-mentioned standards, there are various national standards that may apply depending on the country of operation.
Standard Development Organizations
ASTM International is one of the leading standard development organizations in the world. Other notable organizations include:
