1.1 This test method describes the design and use of a thin metallic calorimeter for the measurement of heat-transfer rate using a steady one-dimensional heat flow analysis.
1.2 Advantages:
1.2.1 Simplicity of Construction -The calorimeter may be constructed identical to the material specimen in size and shape, and thermocouples may be attached to the metal by spot, electron beam, or laser beam welding.
1.2.2 Heat-transfer rate distribution may be obtained if metals of low thermal conductivity are used.
1.2.3 Smooth continuous surface without insulators or plugs for more realistic flow simulation.
1.2.4 This test method is relatively inexpensive and, if necessary, may be operated to burn-out to obtain heat-transfer rate measurement.
1.3 Limitations:
1.3.1 The short test time necessary to ensure calorimeter survival.
1.3.2 The calorimeter must be operated at pressures and temperatures such that the thin skin does not distort under the pressure loads.
1.4 This standard may involve hazardous materials, operations, and equipment. This standard does not purport to address all of the safety problems 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.
