Such heat treatment must be included in the report. Where some heat or mechanical treatment is applied to the specimen prior to test, this should be noted in the report. 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.

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. Related information can be found in Refs. In a TMA, the specimen is placed in the holder at room asym.

E — 06 is adequate. It is the responsibility of the user to determine the necessary equivalency prior to use. The am shall not be calculated from a temperature range in which a transition point is noted. Users of this test method are astk advised that all such instruments or techniques may not be equivalent.

The actual incremental force, mass, or stress above that required to make contact with zero force shall be noted in the report. The temperature range may be extended depending upon the instrumentation and aastm materials used.

An abrupt change in slope of the expansion curve indicates a transition of the material from one state to another.

Lateral dimensions shall not exceed 10 mm. For the TMA, the test specimen should be between 2 and 10 mm. Send us a request Wilton UK: Other lengths may be used, but shall be noted in the report. This standard is aastm to revision at any time by the responsible technical committee and must be reviewed every?

Specimens that do not meet these requirements may result in increased imprecision. The furnace is raised and the temperature is brought to 20 degrees below the lowest temperature of interest.

Users of this test method are expressly advised that all such instruments or techniques may not be equivalent. Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility.

The test method may be used at lower or negative expansion levels with decreased accuracy and precision see Section. The last approved version of this historical standard is referenced on www. High heating rates, large specimen sizes, and low specimen thermal conductivity may lead to large specimen temperature gradients.

The temperature range may be extended depending upon the instrumentation and calibration materials used. NOTE 3—It has been found with some materials that this level of? 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.

The test method may be used at lower or negative expansion levels with decreased accuracy and precision see Section Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. Inspection Validating the specifications, value and safety of your raw materials, products and assets. Linear Thermal Expansion is used to determine the rate at which a material expands as a function of temperature.
