ASTM E473-06 与热分析和热流变相关的标准术语

1.1 This terminology is a compilation of definitions of terms used in ASTM documents relating to thermal analysis and rheology. This terminology includes only those terms for which ASTM either has standards or is contemplating some action. It is not intended to be an all-inclusive listing of terms related to thermal analysis and rheology.1.2 This terminology specifically supports the single-word form for terms using thermo-as a prefix, such as thermoanalytical or thermomagnetometry, while recognizing that for some terms a two-word form can be used, such as thermal analysis. This terminology does not support, nor does it recommend, use of the grammatically incorrect, single-word form using thermalas a prefix, such as, thermalanalytical or thermalmagnetometry.1.3 Definitions that are similar to those published by another standards body are identified with the abbreviation of the name of the organization: for example, ICTAC is the International Confederation for Thermal Analysis and Calorimetry.1.4 A definition is a single sentence with additional information included in notes. It is reviewed every five years, and the year of the last review or revision is appended.

Standard Terminology Relating to Thermal Analysis and Rheology

ASTM E1867-06 动态机械分析仪的温度校准用标准试验方法

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 -150 to 500176;C.1.2 SI units are the standard1.3 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.

Standard Test Method for Melting And Crystallization Temperatures By Thermal Analysis

ASTM E1970-06 热分析数据的统计处理的标准操作规程

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 SI units are the standard.1.5 There are no ISO methods equivalent to this practice.

ASTM E2403-06 用热解重量分析法测定有机材料的硫酸盐灰分的标准试验方法

The sulfated ash may be used to indicate the level of known metal-containing additives or impurities in an organic material. When phosphorus is absent, barium, calcium, magnesium, sodium and potassium are converted to their sulfates. Tin and zinc are converted to their oxides. This standard may be used for research and development, specification acceptance and quality assurance purposes. 1.1 This standard describes the determination of sulfated ash content (sometimes called residue-on-ignition) of organic materials by thermogravimetry. The method converts common metals found in organic materials (such as sodium, potassium, lithium, calcium, magnesium, zinc, and tin0 into their sulfate salts permitting estimation of their total content as sulfates or oxides. The range of the test method is from 0.1 to 100 % metal content.1.2 SI values are the standards.1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use.

ASTM E637-05 通过临界点传热与压力的热传递理论和实验测量来计算临界热函的标准试验方法

The purpose of this test method is to provide a standard calculation of the stagnation enthalpy of an aerodynamic simulation device using the heat transfer theory and measured values of stagnation point heat transfer and pressure. A stagnation enthalpy obtained by this test method gives a consistent set of data, along with heat transfer and stagnation pressure for ablation computations.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 Advantages1.2.1 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 ConsiderationsThere are many factors that may contribute to an error using this type of approach to calculate stagnation enthalpy, including:1.3.1 TurbulenceThe 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 GasThe reaction rates and expansions may be such that the gas is far from thermodynamic equilibrium.1.3.3 Noncatalytic EffectsThe 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 CurrentsThe arc-heated gas stream may have free electric currents that will contribute to measured experimental heat transfer rates.1.3.5 Nonuniform Pressure ProfileA 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 EffectsThe 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 ShapeThe nondimensional stagnation-point velocity gradient is a function of model shape.1.3.8 Radiation EffectsThe 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 Method E 469 and Test Methods E 422, E 457, E 459, and E 511).1.3.10 ContaminationThe electrode material may be of a large enough percentage of the mass flow rate to contribute to the heat transfer rate measurement.1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.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.
