It is the responsibility of the user to determine the necessary equivalency prior to use. Linear Thermal Expansion is used to determine the rate at which a material expands as a function of temperature.
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. Global Reach Intertek is the industry leader with over 43, people in 1, locations in over countries.
For the dilatometer, the test sample should be approximately A small sample of polymeric material is heated on a quartz platform, and a rod applies a small amount of pressure.
Assurance Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes.
Element’s fatigue testing labs help companies meet quality requirements and create safer, stronger, more successful parts and products. While TMA can be performed on virtually any polymeric material, it is most effective on samples with a high coefficient of thermal expansion. Link to Active This link will always route to the current Active version of the aastm.
ASTM E – THERMAL EXPANSION BY TMA
The specimen must be flat on both ends. Whether your business is local or global, we can ensure your products meet quality, health, environmental, safety, and social accountability standards for virtually any market around the world. For the TMA, the test specimen should be between 2 and 10 mm.
Our experts have knowledge in experience in a wide variety of industries and applications, and are involved in a diverse group of standards and materials organizations. The test method may be used at lower or negative expansion levels with decreased accuracy and precision see Section This test can be used for design purposes and to astmm if failure by thermal stress may occur.

The specimen must be flat on both ends. Assurance Testing Inspection Certification. A graph is produced. Users of this test method are expressly advised that all such instruments or techniques may not be equivalent. The coefficient of linear thermal expansion is calculated between the desired temperature ranges. Our deliverable is certainty – high quality data, test reports and certifications that you can rely on when making decisions about your materials and components.
Coefficient of Linear Thermal Expansion (CLTE) – ASTM E831
Alternatively, a dilatometer can be used. Due to copyright restrictions, we are not able to provide copies of standards. The specimen is placed in the Dilatometer at room temperature, and the height gauge is positioned and zeroed. For the TMA, the test specimen should be between 2 and 10 mm. The temperature range may be extended depending upon the instrumentation and calibration materials used. Linear Thermal Expansion is used to determine the rate at which a material expands as a function of temperature.
