1.1x00a0;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. 1.2x00a0;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. 1.3x00a0;Electrical safety is not a part of this specification. 1.4x00a0;Mechanical safety (including pressure safety) is not a part of this specification. 1.5x00a0;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. 1.6x00a0;This standard does not purport to address all of the safety concerns, if any, associated with its use.

5.1x00a0;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. 5.2x00a0;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. 5.2.1x00a0;The applied heat flux, q, shall be obtained from steady-state tests conducted in accordance with either Test Method C177, C518, C1363, or C1114. 5.2.2x00a0;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:x00a0;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. 5.3x00a0;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. 5.4x00a0;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. 5.5x00a0;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.

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 x03BC;m/(mx00B7;x00B0;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 x2212;120 to 900 x00B0;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.

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 800x00B0;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 x00B0;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.

Dynamic mechanical analyzers monitor changes in the viscoelastic properties of a material as a function of temperature and frequency, providing a means to quantify these changes. In most cases, the value to be assigned is the temperature of the transition (or event) under study. Therefore, the temperature axis (abscissa) of all DMA thermal curves must be accurately calibrated by adjusting the apparent temperature scale to match the actual temperature over the temperature range of interest.1.1 This test method describes the temperature calibration of dynamic mechanical analyzers (DMA) from x2013;150 x00B0;C to 500 x00B0;C. 1.2 The values stated in SI units are to be regarded as standard. 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. Specific precautionary statements are given in Note 7.
