Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

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

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

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. It requires only a small easily fabricated specimen. 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.

Nevertheless, such data, while usually lacking absolute accuracy, may be useful in comparing materials of similar structure. Active view current version of standard. 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. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

It is advisable to use aztm materials to verify the performance of the instrument used. The short measurement times involved reduce the chances of contamination and change of specimen properties due to exposure to high temperature environments.

Active view current version of standard. Thermal diffusivity values in the range from 0.

Thermal diffusivity values ranging from 0. 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 the e146 of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. 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.
