It is the responsibility of the user of this standard to establish appropriate safety and health practices and ashm the applicability of regulatory limitations prior to use.

Thermal diffusivity values ranging from 0. Link to Active This link will always route to the current Active version of the standard. 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 requires only a small easily fabricated specimen. e11461

For this technique, specially constructed sample enclosures must be used. Special caution is advised when other properties, such as thermal conductivity, are derived from thermal diffusivity obtained by this method.
