1.1 This test method describes the measurement of radiative or convective heat flux, or both, using a transducer whose sensing element (1, 2) is a thin circular metal foil. While benchmark calibration standards exist for radiative environments, no uniform agreement among practitioners or government entities exists for convective environments.1.2 The values stated in SI units are to be regarded as the standard. The values stated in parentheses are provided for information only.1.3 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.

ASTM E637-98 通过热传导理论及滞点传热性与压力的实验测量来计算滞点热函的试验方法

1.1 This test method covers the calculation from heat transfer theory of the stagnation enthalpy from experimental measurements of the stagnation-point heat transfer and stagnation pressure. 1.2 Advantages: 1.2.1 A value of stagnation enthalpy can be obtained at the location in the stream where the model is tested. This value gives a consistent set of data, along with heat transfer and stagnation pressure, for ablation computations. 1.2.2 This computation of stagnation enthalpy does not require the measurement of any arc heater parameters. 1.3 Limitations and Considerations -There are many factors that may contribute to an error using this type of approach to calculate stagnation enthalpy, including: 1.3.1 Turbulence -The turbulence generated by adding energy to the stream may cause deviation from the laminar equilibrium heat transfer theory. 1.3.2 Equilibrium, Nonequilibrium, or Frozen State of Gas -The reaction rates and expansions may be such that the gas is far from thermodynamic equilibrium. 1.3.3 Noncatalytic Effects -The surface recombination rates and the characteristics of the metallic calorimeter may give a heat transfer deviation from the equilibrium theory. 1.3.4 Free Electric Currents -The arc-heated gas stream may have free electric currents that will contribute to measured experimental heat transfer rates. 1.3.5 Nonuniform Pressure Profile -A nonuniform pressure profile in the region of the stream at the point of the heat transfer measurement could distort the stagnation point velocity gradient. 1.3.6 Mach Number Effects -The nondimensional stagnation-point velocity gradient is a function of the Mach number. In addition, the Mach number is a function of enthalpy and pressure such that an iterative process is necessary. 1.3.7 Model Shape -The nondimensional stagnation-point velocity gradient is a function of model shape. 1.3.8 Radiation Effects -The hot gas stream may contribute a radiative component to the heat transfer rate. 1.3.9 Heat Transfer Rate Measurement -An error may be made in the heat transfer measurement (see Methods E469 and Test Methods E422, E457, E459, and E511). 1.3.10 Contamination -The electrode material may be of a large enough percentage of the mass flow rate to contribute to the heat transfer rate measurement. 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.

ASTM F1943-98(2008) 测定热质量传递带状产品的动态导热性的标准试验方法.ATLANTEK方法

The Atlantek test system allows simulation of the printing conditions of thermal transfer printers in the marketplace. Thus, this system is useful in matching thermal transfer product performance to various thermal printheads. This test system is useful for new product development. Thermal transfer printer manufacturers can design print control algorithms to match particular printhead designs to thermal imaging products. Thermal imaging product manufacturers can formulate and design products (media) to provide a match with certain printhead designs. Manufacturing process control can make thermal response comparisons relative to process changes. Customers for thermal products can use this test method to compare supplies from various manufacturers. The test system can be used to evaluate thermal response of facsimile, label, medical recorder, plotter, and other thermal transfer products (media). Performance differences between printheads and media combinations can be measured and presented graphically. The interrelationship between printing control variables can also be studied.1.1 This test method covers the measurement of thermal response of various thermal mass transfer ribbons used for facsimile, labels, medical recorders, plotters, and printers. 1.2 The Atlantek Thermal Response Tester Model 200 described in this test method may be used for specification acceptance, product development, and research applications. Although this test method identifies specific printheads, the tester does support additional printheads. 1.3 The values stated in inch-pound units are to be regarded as standard. No other units of measurement are included in this standard. 1.4 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. For specific precautionary statements, see Section 8.

ASTM C518-98 用热流计法测定稳态热通量和热传递特性的标准试验方法

1.1 This test method covers the measurement of steady state thermal transmission through flat slab specimens using a heat flow meter apparatus. 1.2 This is a comparative (or secondary) method of measurement since specimens of known thermal transmission properties must be used to calibrate the apparatus. Properties of the calibration specimens must be traceable to an absolute measurement method, and should be obtained from or traceable to a recognized national standards laboratory. 1.3 The test method is applicable to the measurement of thermal transmission through a wide range of specimen properties and environmental conditions. The method has been used at ambient conditions of 10 to 40176C with thicknesses up to approximately 250 mm, and with plate temperatures from -195176C to 540176C at 25 mm thickness (Refs. (5, 6)). 1.4 This test method may be used to characterize material properties which may or may not be representative of actual conditions of use. Other test methods such as Test Methods C236 or C976 should be used if needed. 1.5 To meet the requirements of this test method the thermal resistance of the sample must be greater than 0.10 K[dot]m /W in all directions. 1.6 It is not practical in a test method of this type to try to establish details of construction and procedures to cover all contingencies that might offer difficulties to a person without pertinent technical knowledge. Thus users of this test method shall have sufficient knowledge to satisfactorily fulfill their needs. For example, knowledge of heat transfer principles, low level electrical measurements, and general test procedures is required. 1.7 Standardization of this test method is not intended to restrict in any way the future development of improved or new methods or procedures by research workers. 1.8 Since the design of a heat meter apparatus is not a simple matter, a procedure for qualifying an apparatus is given in 7.8. 1.9 This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to consult and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
