1.1This test method covers the determination of instantaneous and mean values of the specific heat of rock and soil.
1.2This test method employs the classical method of mixtures, which involve procedures and an apparatus that are simpler than those generally used in scientific calorimetry, but with an accuracy that is adequate for most rocks and soils. While this test method was developed for testing rock and soil, it can be adapted to measure the specific heat of other materials.
1.3The testing procedure provides an instantaneous specific heat over temperatures ranging from 25 to 300°C or a mean specific heat in that temperature range.
1.4The test procedure is limited to dry specimens of soil and rock.
1.5Units—The values stated in SI units are to be regarded as the standard. No other units of measurements are included in this standard.
1.6All observed and calculated values shall conform to the guidelines for significant digits and rounding established in Practice D6026.
1.6.1The procedure used to specify how data are collected/recorded or calculated in this standard are regarded as the industry standard. In addition, they are representative of the significant digits that generally should be retained. The procedures used do not consider material variation, purpose for obtaining the data, special purpose studies, or any considerations for the user’s objectives; and it is common practice to increase or reduce significant digits of reported data to be commensurate with these considerations. It is beyond the scope of this standard to consider significant digits used in analytical methods for engineering design
1.7This 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.
