Nevertheless, such data, while usually lacking absolute accuracy, may be useful in comparing materials of similar structure. Thermal diffusivity values ranging from 0. It is not practical in a test method of this type to establish details of construction and procedures to cover all contingencies that might offer difficulties to a person without pertinent technical knowledge, or to s1461 or restrict research and development for improvements in the basic technique.

It requires only a small easily fabricated specimen.

No other units of measurement are included in this standard. Extreme caution must be exercised when related properties, such as thermal conductivity, are derived, as composites may have heat flow patterns substantially different than uniaxial.

Comparing Thermal Conductivity Methods

It is not practical in a test method of this satm to establish details of construction and procedures to cover all contingencies that might offer difficulties to a person without pertinent technical knowledge, or to stop or restrict research and development for improvements in the basic technique. Active view current version of standard. It is particularly advantageous because of simple specimen geometry, small specimen size requirements, rapidity of measurement and ease of handling.

ASTM E – 07 Standard Test Method for Thermal Diffusivity by the Flash Method

It is particularly advantageous because of the simple specimen geometry, small specimen size requirements, rapidity of measurement, and ease of handling materials having a wide range of thermal diffusivity values over a large temperature range with a single apparatus. Active view current version of standard.

For this technique, specially constructed sample enclosures must be used. Experience has shown, however, that some deviation from these strict guidelines can be accommodated with care and proper experimental design, substantially broadening the usefulness of the method.

It is advisable to use reference materials to verify the performance of the instrument used. Thermal diffusivity values in the range from 0. F0 Book of Standards Volume: For guidance on converting thermal diffusivity to thermal conductivity, refer to Practice C It is not practical in a test method of this type to establish details of construction and procedures to cover all contingencies that might offer difficulties to a person without pertinent technical knowledge, or to restrict research and development for improvements in the basic technique.

Experience shows that some deviation from these strict guidelines can be accommodated with care and proper experimental design, substantially broadening the usefulness of the method. Special caution is advised when other properties, such as thermal conductivity, are derived from thermal diffusivity obtained by this method.

The short measurement times involved reduce the chances of contamination and change of specimen properties due to exposure to high temperature environments.

In some cases, contact conductance of the interface may also be determined. Link to Active This link will always route to the current Active version of the standard. 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.

Since the magnitude of porosity, pore shapes, sizes and parameters of pore distribution influence the behavior of the thermal diffusivity, extreme caution must be exercised when analyzing data.
