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 stop or restrict research and development for improvements in the basic technique.

It is particularly advantageous because of simple specimen geometry, small specimen size requirements, rapidity of measurement and ease of handling. 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.

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. Link to Active This link will always route to the current Active version of the standard. Link to Active This link will always route to the current Active version of the standard.

It requires only a small easily fabricated specimen. 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.

Thermal diffusivity values in the range 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 stop or restrict research and development for improvements in the basic technique.

It is advisable to use reference materials to verify the performance of the instrument used. Astj, such data, while usually lacking absolute accuracy, may be useful in comparing materials of similar structure. Thermal diffusivity values ranging from 0.

The two documents are complementing each other.

In some cases, contact conductance of the interface may also be determined. Special caution is advised when other properties, such as thermal conductivity, are derived from thermal diffusivity obtained by this method.

ASTM E – 01 Standard Test Method for Thermal Diffusivity of Solids by the Flash Method

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

For this technique, specially constructed sample enclosures must be used. For guidance on converting thermal diffusivity to thermal conductivity, refer to Practice C 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.
