For guidance on converting thermal diffusivity to thermal conductivity, refer to Practice C Since the magnitude of porosity, pore shapes, sizes f1461 parameters of pore distribution influence the behavior of the thermal diffusivity, extreme caution must be exercised when analyzing data.

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. Nevertheless, such data, while usually lacking absolute accuracy, may e1641 useful in comparing materials of similar structure. 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.

Comparing Thermal Conductivity Methods

It requires only a small easily fabricated specimen. Special caution is advised when other properties, such as thermal conductivity, are derived from thermal diffusivity obtained by this 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. F0 Book of Standards Volume: 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.

It is advisable to use reference materials to verify the performance of the instrument used. Link to Active This link will always route to the current Active version of the standard.

It is particularly advantageous because of simple specimen geometry, small specimen size requirements, rapidity of measurement and ease of handling. The short measurement times involved reduce the chances of contamination and change of specimen properties due to exposure to high temperature environments.
