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.

Special caution is advised when other properties, such as thermal conductivity, are derived from thermal diffusivity obtained by this method. No other units of measurement are included in this standard. Active view current aastm 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 stop or ast research and development for improvements in the basic technique. 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.

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 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 is advisable to use reference materials to verify the e14461 of the instrument used. Asm is the responsibility e161 the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

The short measurement times involved reduce the chances of contamination and change of specimen properties due to exposure to high temperature environments. F0 Book of Standards Volume: 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.

For this technique, specially constructed sample enclosures must be used. It is advisable to use reference materials to verify the performance of the instrument used. Nevertheless, such data, while usually lacking absolute accuracy, may be useful in comparing materials of similar structure. It is the responsibility f1461 the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. 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. No other units of measurement are included in this standard.

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