The two documents are complementing each other.

For this technique, specially constructed sample enclosures must be used. 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.

Active view current version of standard. 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. The short measurement times involved reduce the chances of contamination and change of specimen properties due to exposure to high temperature environments.

Comparing Thermal Conductivity Methods

It requires only a small easily fabricated specimen. 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. In some cases, contact conductance of the interface may also be determined.

Active view current version of standard. Nevertheless, such data, while usually lacking absolute accuracy, may be useful in comparing materials of similar structure. For guidance on converting thermal diffusivity to thermal conductivity, refer to Practice C 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 stop or restrict research and development for improvements in the basic technique.
