1.1 This test method describes the measurement of thermal effusivity of solids over the range of 42 W s1/2/(m2 K) to 31 000 W s1/2/(m2 K) using the modified transient plane source method at ambient temperature. Test specimens are commonly right circular cylinders 2 to 3 cm in diameter and 0.1 to 3 cm in length; however, larger specimens may be used. Test specimens shall be isotropic. 1.2 SI units are the standard. 1.3 This 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.
