The short measurement times involved reduce the chances of contamination and change of specimen properties due to exposure to high temperature environments. It requires only a small easily fabricated specimen. 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.

The two documents are complementing each other. 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. The two documents are complementing each other.

Comparing Thermal Conductivity Methods

Nevertheless, such data, while usually lacking absolute accuracy, may be useful in comparing materials of similar structure. For this technique, specially constructed sample enclosures must be used. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

Special caution is advised when other properties, such as thermal conductivity, are derived from thermal diffusivity obtained by this method. 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.

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. E14611 other units of measurement are included in this standard. In ee1461 cases, contact conductance of the interface may also be determined. It is sstm responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

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. For guidance on converting thermal diffusivity to thermal conductivity, refer to Practice C Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
