Significance and Use

Specific heat is a basic thermodynamic property of all substances. The value of specific heat depends upon chemical composition and temperature. The rate of temperature diffusion through a material, thermal diffusivity, is a function of specific heat; therefore, specific heat is an essential property of rock and soil when these materials are used under conditions of unsteady or transient heat flow.

Scope

1.1 This test method covers the determination of instantaneous and mean specific heat of rock and soil.

1.2 This test method employs the classical method of mixtures. This provides procedures and apparatus simpler than those generally used in scientific calorimetry, an accuracy that is adequate for most rocks and soils, and a degree of precision that is reproducible by laboratory technicians of average skill. While this test method was developed for testing rock and soil, it is easily adaptable to measuring the specific heat of other materials.

1.3 The testing procedure provides an instantaneous specific heat over the temperature 25 to 300oC or a mean specific heat in that temperature range.

1.4 The test procedure is limited to dry samples.

1.5 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.
