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

The short measurement times involved reduce the chances of contamination and change of specimen properties due to exposure to high temperature environments. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

No other units of measurement are included in this standard. It is particularly advantageous because of simple specimen geometry, small specimen size requirements, rapidity of measurement and ease of handling. 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.

E4161 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. 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.

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. For this technique, specially constructed sample enclosures must be used. No other units of measurement are included in this standard.

In some cases, contact conductance of the interface may also be determined. 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.
