Linear Thermal Expansion by TMA or Dilatometer
For the dilatometer, the test sample should be approximately Data is reported as a function of dimensional change of the material over temperature, and significant milestones are recorded. Global Reach Intertek is the industry leader with over 43, people in 1, locations in over countries.
The specimen is heated at a specified rate, often ten degrees a minute, over the desired temperature range. A small sample of polymeric material is heated on a quartz platform, and a rod applies a small amount of pressure.
Users of this test method are expressly advised that all such instruments or techniques may not be equivalent. Both Charpy and Izod impact testing are popular methods of determining impact strength, or toughness, of a material. Due to copyright restrictions, we are not able to provide copies of standards.

ASTM E Linear Thermal Expansion of Solid Materials by Thermomechanical Analysis_百度文库
As the samples gets warmer, the material expands and the rod changes positions. The temperature range may be extended depending upon the instrumentation and calibration materials used. The furnace is raised and the temperature is brought to 20 degrees below the lowest temperature of interest. Contact us today to leverage our expertise for your next project.
