5.1 This method is suitable for determining the total heat of hydration of hydraulic cement at constant temperature at ages up to 7 days to confirm specification compliance. It gives test results equivalent to Test Method C186 up to 7 days of age (1).3 5.2 This method compliments Practice C1679 by providing details of calorimeter equipment, calibration, and operation. Practice C1679 emphasizes interpretation significant events in cement hydration by analysis of time dependent patterns of heat flow, but does not provide the level of detail necessary to give precision test results at specific test ages required for specification compliance. 1.1 This test method specifies the apparatus and procedure for determining total heat of hydration of hydraulic cementitious materials at test ages up to 7 days by isothermal conduction calorimetry. 1.2 This test method also outputs data on rate of heat of hydration versus time that is useful for other analytical purposes, as covered in Practice C1679. 1.3 The values stated in SI 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.

ASTM E1952-17 用调整温度的差示扫描量热法测量导热性和热扩散率的标准试验方法

5.1 Thermal conductivity is a useful design parameter for the rate of heat transfer through a material. 5.2 The results of this test method may be used for design purposes, service evaluation, manufacturing control, research and development, and hazard evaluation. (See Practice E1231.) 1.1 This test method describes the determination of thermal conductivity of homogeneous, non-porous solid materials in the range of 0.10 W/(K8201;•8201;m) to 1.08201;W/(K8201;•8201;m) by modulated temperature differential scanning calorimeter.

ASTM E3137/E3137M-17 热计量仪表的标准规格

1.1 This specification defines general specifications for heat meters. Heat meters are instruments that measure heat in heat exchange circuits in which energy is absorbed (cooling) or given up (heating) by a flowing liquid. 1.2 For this specification, the necessary elements of a heat meter consist of a sensor to measure flow of the heat-conveying liquid, a pair of temperature sensors that measure the temperature differential across the heat exchange circuit, and a device that receives input from the flow and temperature sensors and calculates energy. 1.3 Electrical safety is not a part of this specification. 1.4 Mechanical safety (including pressure safety) is not a part of this specification. 1.5 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard. 1.6 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Specification for Heat Meter Instrumentation

ASTM C1130-17 薄热流量传感器校准的标准实施规程

5.1 The application of HFTs and temperature sensors to building envelopes provide in-situ data for evaluating the thermal performance of an opaque building component under actual environmental conditions, as described in Practices C1046 and C1155. These applications require calibration of the HFTs at levels of heat flux and temperature consistent with end-use conditions. 5.2 This practice provides calibration procedures for the determination of the heat flux transducer sensitivity, S, that relates the HFT voltage output, E, to a known input value of heat flux, q. 5.2.1 The applied heat flux, q, shall be obtained from steady-state tests conducted in accordance with either Test Method C177, C518, C1363, or C1114. 5.2.2 The resulting voltage output, E, of the heat flux transducer is measured directly using (auxiliary) readout instrumentation connected to the electrical output leads of the sensor. Note 1: A heat flux transducer (see also Terminology C168) is a thin stable substrate having a low mass in which a temperature difference across the thickness of the device is measured with thermocouples connected electrically in series (that is, a thermopile). Commercial HFTs typically have a central sensing region, a surrounding guard, and an integral temperature sensor that are contained in a thin durable enclosure. Practice C1046, Appendix X2 includes detailed descriptions of the internal constructions of two types of HFTs. 5.3 The HFT sensitivity depends on several factors including, but not limited to, size, thickness, construction, temperature, applied heat flux, and application conditions including adjacent material characteristics and environmental effects. 5.4 The subsequent conversion of the HFT voltage output to heat flux under application conditions requires (1) a standardized technique for determining the HFT sensitivity for the application of interest; and, (2) a comprehensive understanding of the factors affecting its output as described in Practice C1046. 5.5 The installation of a HFT potentially changes the local thermal resistance of the test artifact and the resulting heat flow differs from that for the undisturbed building component.

ASTM E831-12 热力分析法测试固体材料线性热膨的标准试验方法

Coefficients of linear thermal expansion are used, for example, for design purposes and to determine if failure by thermal stress may occur when a solid body composed of two different materials is subjected to temperature variations. This test method is comparable to Test Method D3386 for testing electrical insulation materials, but it covers a more general group of solid materials and it defines test conditions more specifically. This test method uses a smaller specimen and substantially different apparatus than Test Methods E228 and D696.1.1 This test method determines the apparent coefficient of linear thermal expansion of solid materials using thermomechanical analysis techniques. 1.2 This test method is applicable to solid materials that exhibit sufficient rigidity over the test temperature range such that the sensing probe does not produce indentation of the specimen. 1.3 The recommended lower limit of coefficient of linear thermal expansion measured with this test method is 5 μm/(m·°C). The test method may be used at lower (or negative) expansion levels with decreased accuracy and precision (see Section 11). 1.4 This test method is applicable to the temperature range from −120 to 900 °C. The temperature range may be extended depending upon the instrumentation and calibration materials used. 1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.6 This test method is related to ISO 11359-2 but is significantly different in technical detail. 1.7 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 establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

ASTM E2550-11 热重分析法测定热稳定性的标准试验方法

TG provides a rapid method for determining the thermal decomposition and reaction mass change of a material. This test method is useful in detecting potentially hazardous reactions and in estimating the temperatures at which these reactions occur. This test method is recommended as a screening test for detecting the thermal hazards of an uncharacterized material or mixture (see Section 8). Energetic materials, pharmaceuticals and polymers are examples of materials for which this test might be useful. This test is especially useful for materials having melting points that overlap with the onset of reaction or decomposition. Note 18212;In Differential Scanning Calorimetry (DSC), the melting endotherm may interfere with the determination of the onset temperature for reaction or decomposition. This test is not suitable for materials that sublime or vaporize in the temperature range of interest. A sample with volatile impurities needs to be purified prior to the TGA testing. Alternatively, the sample can be tested as is, however, special caution is required during the data analysis. The mass loss due to the loss of impurity should not interfere with the determination of reaction or decomposition temperature. The four significant criteria of this test method are: the detection of a sample mass change; the extent of the mass change; the approximate temperature at which the event occurs; the observance of effects due to the atmosphere.1.1 This test method covers the assessment of material thermal stability through the determination of the temperature at which the materials start to decompose or react and the extent of the mass change using thermogravimetry. The test method uses minimum quantities of material and is applicable over the temperature range from ambient to 800°C. 1.2 The absence of reaction or decomposition is used as an indication of thermal stability in this test method under the experimental conditions used. 1.3 This test method may be performed on solids or liquids, which do not sublime or vaporize in the temperature range of interest. 1.4 This test method shall not be used by itself to establish a safe operating or storage temperature. It may be used in conjunction with other test methods (for example, E487, E537 and E1981) as part of a hazard analysis of a material. 1.5 This test method is normally applicable to reaction or decomposition occurring in the range from room temperature to 800 °C. The temperature range may be extended depending on the instrumentation used. 1.6 This test method may be performed in an inert, a reactive or self-generated atmosphere. 1.7 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.8 There is no ISO standard equivalent to this test method. 1.9 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. This standard may involve hazardous materials, operations, and equipment.

Standard Test Method for Thermal Stability by Thermogravimetry

ASTM E1970-11 热分析数据统计处理标准规程

The standard deviation, or one of its derivatives, such as relative standard deviation or pooled standard deviation, derived from this practice, provides an estimate of precision in a measured value. Such results are ordinarily expressed as the mean value ± the standard deviation, that is, X ± s. If the measured values are, in the statistical sense, “normally” distributed about their mean, then the meaning of the standard deviation is that there is a 67 % chance, that is 2 in 3, that a given value will lie within the range of ± one standard deviation of the mean value. Similarly, there is a 95 % chance, that is 19 in 20, that a given value will lie within the range of ± two standard deviations of the mean. The two standard deviation range is sometimes used as a test for outlying measurements. The calculation of precision in the slope and intercept of a line, derived from experimental data, commonly is required in the determination of kinetic parameters, vapor pressure or enthalpy of vaporization. This practice describes how to obtain these and other statistically derived values associated with measurements by thermal analysis.1.1 This practice details the statistical data treatment used in some thermal analysis methods. 1.2 The method describes the commonly encountered statistical tools of the mean, standard derivation, relative standard deviation, pooled standard deviation, pooled relative standard deviation and the best fit to a straight line, all calculations encountered in thermal analysis methods. 1.3 Some thermal analysis methods derive the analytical value from the slope or intercept of a best fit straight line assigned to three or more sets of data pairs. Such methods may require an estimation of the precision in the determined slope or intercept. The determination of this precision is not a common statistical tool. This practice details the process for obtaining such information about precision. 1.4 There are no ISO methods equivalent to this practice.
