If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at atsm address shown below. Place the specimen temperature sensor in contact with the specimen or as near to the specimen as possible. The test method may be used at lower or negative expansion levels with decreased accuracy and precision see Section Note 1 Users of this test method are expressly advised that all such instruments or techniques may not be equivalent.
Asttm refrigerant used for cooling shall not come into direct contact with the specimen. Send us a request Wilton UK: NOTE 4—Some materials, particularly composites, may require heat treatment to condition the specimen prior to test to relieve stresses or distortions.

Astk is the responsibility of the user to determine the necessary equivalency prior to use. Coefficient of Linear Thermal Expansion Video Learn more about linear thermal expansion in this video.
Material Testing Coefficient of Expansion,? The effects of specimen temperature gradients may be compensated for by correction found through the use of suitable reference materials whose size and thermal conductivity are close to that of the test specimen.

The test method may be used at e8311 or negative expansion levels with decreased accuracy and precision see Section. Lateral dimensions shall not exceed 10 mm.
Auditing Consulting Sourcing Training. This standard does not purport to address all of the safety problems, if any, associated with asgm use. Unless effects of moisture are wstm be studied, use of dry purge gas is recommended and is essential for operation at subambient temperatures. Originally approved in Due to copyright restrictions, we are not able to provide copies of standards. Global Reach E31 is the industry leader with over 42, people in 1, locations in over countries.
The observed expansion must be corrected for the difference in expansion between the specimen holder and probe obtained from a blank run in which no sample or a specimen of the material of construction of the probe is run. Whether your business is local or global, we can ensure your products meet quality, 8e31, 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.
