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

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

No other units of measurement are included in this standard. The two documents are complementing each other. 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.

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

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.

Experience has shown, however, that some deviation from e14661 strict guidelines can be accommodated with care and proper experimental design, substantially broadening the usefulness of the method. Active view current version of standard. It requires only a small easily fabricated specimen. For guidance on converting thermal diffusivity to thermal conductivity, refer to Practice C Link to Active This link will always route to the current Active version of the standard.

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 e146. Nevertheless, such data, while usually lacking absolute accuracy, may be useful in comparing materials of similar structure.
