Standard Test Method for Determining Specific Heat Capacity by Differential Scanning Calorimetry
Specific heat capacity is measured by differential scanning calorimetry. The sample size for oxides is a 0.232" diameter x 0.527" high cylinder and for non-oxides is a 0.192" diameter x 0.456" high cylinder.
SIGNIFICANCE AND USE
Differential scanning calorimetric measurements provide a rapid, simple method for determining specific heat capacities of materials.
Specific heat capacities are important for reactor and cooling system design purposes, quality control, and research and development.
1.1 This test method covers the determination of specific heat capacity by differential scanning calorimetry.
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 can be extended, depending upon the instrumentation and specimen holders used.
1.4 The values stated in SI units are to be regarded as the standard.
1.5 Computer or electronic-based instrumentation, techniques, or data treatment equivalent to this test method may be used.
Note 1-Users of this test method are expressly advised that all such instruments or techniques may not be equivalent. It is the responsibility of the user of this test method to determine equivalency prior to use.
1.6 This method is similar to ISO 11357-4, but contains additional methodology not found in that method. Additionally, ISO 11357-4 contains practices not found in this standard. This method is similar to Japanese Industrial Standard K 7123, but contains additional methodology not found in that method.
1.7 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. Specific precautionary statements are given in Section 9.
