It is not practical in a test method of this type to establish details of construction and procedures to cover all asgm 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. Experience has shown, however, that some deviation from these strict guidelines can be accommodated with care and proper experimental aastm, substantially broadening the usefulness of the method.

It is advisable to use reference 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. 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. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

Thermal diffusivity values ranging 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. asmt

Active view current version of standard. 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. Special caution is advised when other properties, such as thermal conductivity, are derived from thermal diffusivity obtained by this method.

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 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.

It requires only a small easily fabricated specimen. In some cases, contact conductance of the interface may also be determined. Nevertheless, such data, while usually lacking absolute accuracy, may be useful in comparing materials of similar structure.
