1.1This test method covers the determination of the thermal diffusivity of carbons and graphite at temperatures up to 500 °C. It requires only a small easily fabricated specimen. Thermal diffusivity values in the range from 0.04 cm²/s to 2.0 cm²/s are readily measurable by this test method; however, for the reason outlined in Section 7, for materials outside this range this test method may require modification.

1.2This standard does not purport to address all of the safety concerns, if any, associated with its use. 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.

1.3This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
