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

The two documents are complementing each other. It requires only a small easily fabricated specimen. Thermal diffusivity values in the range from 0. 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.

F0 Book of Standards Volume: No other units of measurement are included in this standard.

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

No other units of measurement are included in this standard. It is advisable to use reference materials to verify the performance of the instrument used.

Comparing Thermal Conductivity Methods

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.
