Significance and Use
5.1 Modulated temperature differential scanning calorimetric measurements provide a rapid, simple method for determining specific heat capacities of materials, even under quasi-isothermal conditions.
5.2 Specific heat capacities are important for design purposes, quality control, and research and development.
5.3 The use of a stepped quasi-isothermal program may be used to follow structure changes in materials.
1.1 This test method describes the determination of specific heat capacity by sinusoidal modulated temperature differential scanning calorimetry. For the determination of specific heat capacity by a step-isothermal or multiple step-isothermal temperature program, the reader is referred to Test Method E1269.
1.2 This test method is generally applicable to thermally stable solids and liquids.
1.3 The normal operating range of the test is from –100 to 600°C. The temperature range may be extended depending upon the instrumentation and specimen holders used.
1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
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.
