ASTM E487-20 化学材料恒温稳定性的标准试验方法

1.1 These test methods describe the assessment of constanttemperature stability (CTS) of chemical materials that undergo exothermic reactions. The techniques and apparatus described may be used on solids, liquids, or slurries of chemical substances. 1.2 When a series of materials is tested by these test methods, the results permit ordering the materials relative to each other with respect to their thermal stability. 1.3 Limitations of Test: 1.3.1 These test methods are limited to ambient temperatures and above. 1.3.2 These test methods determine neither a safe storage temperature nor a safe processing temperature. NOTE 1—A safe storage or processing temperature requires that any heat produced by a reaction be removed as fast as generated and that proper consideration be given to hazards associated with reaction products. 1.3.3 When these test methods are used to order the relative thermal stability of materials, the tests must be run under the same confinement condition (see 8.3). 1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.5 This standard should be used to measure and describe the properties of materials, products, or assemblies in response to heat and flame under controlled laboratory conditions and should not be used to describe or appraise the fire hazard or fire risk of materials, products, or assemblies under actual fire conditions. However, results of this test may be used as elements of a fire risk assessment which takes into account all of the factors which are pertinent to an assessment of the fire hazard of a particular end use. 1.6 This standard may involve hazardous materials, operations, and equipment. 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.

1.1 This test method describes the ascertainment of the presence of enthalpic changes in a test specimen, using minimum quantities of material, approximates the temperature at which these enthalpic changes occur and determines their enthalpies (heats) using differential scanning calorimetry or pressure differential scanning calorimetry. 1.2 This test method may be performed on solids, liquids, or slurries. 1.3 This test method may be performed in an inert or a reactive atmosphere with an absolute pressure range from 100 Pa through 7 MPa and over a temperature range from 300 K to 800 K (27 °C to 527 °C). 1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.4.1 Exceptions—Inch-pound units are provided as a courtesy to the user in 5.3, 7.2.2.1, 7.2.2.2, and 11.4. 1.5 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. Specific safety precautions are given in Section 8. 1.6 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.

BS ISO 21256-2:2020 精细气泡技术 清洁应用 机械加工金属零件沾有机油的表面的清洁试验方法

What is ISO 21256 ‑ 2 about?    ISO 21256 discusses cleaning applications by fine bubble technology. ISO 21256 ‑ 2 outlines a test method for the removal of machine oil stain from a non-corrosive metal surface using fine bubble water. A test is provided to show the comparative cleaning advantage of adding fine bubbles to the water.   The main cleaning solvent fluids used in these industries are solvent-based (e.g., hydrocarbon detergent liquids, bromine-containing detergents, and alkali detergents), despite it being well known that such detergents can cause environmental pollution such as ozone layer depletion, water pollution, etc.

T/CGIA 011-2019 石墨烯材料碘吸附值的测定方法

碘吸附值的测定是研究和评价碳材料表面吸附能力较为常见的方法之一，在活性炭和炭黑等产品测试中已广泛使用。国内国际已制定了相关的标准，即GB/T 12496.8-2015《木质活性炭试验方法 碘吸附值的测定》、GB/T 7702.7-2008《煤质颗粒活性炭试验方法 碘吸附值的测定》国家标准、ISO 1304:2016(en)Rubber compounding ingredients — Carbon black — Determination of iodine adsorption number（橡胶配料-炭黑-碘吸附值的测定）等。 石墨烯材料作为一种新型碳纳米材料，具有大理论比表面积（单层石墨烯的理论比表面积为2630 m2/g）、大吸附容量和快速吸附等特点，因此，将碘吸附值测试方法引入石墨烯材料具有重要的现实意义，可作为石墨烯材料吸附能力的测定，质量稳定性控制和下游产品应用开发的评测手段之一。 本标准在制定过程中着重检验了石墨烯材料与碘发生物理吸附能力的重现性，以评价材料表面吸附能力和质量稳定性。对于石墨烯材料表面含有少量常见官能团，如羧基、酚羟基、羰基等，在中性条件下不发生碘仿、卤代等反应，本标准是适用的。若石墨烯材料中含有与碘发生反应的物质，本标准将不适用。本标准通过对多个种类的石墨烯材料粉体样品进行边界条件摸索，建立了适用于石墨烯材料的测试步骤和条件，如试样加入量、碘标准溶液加入量、振荡时间、过滤方式、滴定用滤液体积等，并经过多个实验室间进行比对试验，验证了测试方法的精确度和重现性。本测试方法具有测定快速、方法易于掌握、仪器试剂成本低、结果稳定可靠的特点。

For concentrate containing over 10 000 mg ⁄L, see Practice D4582. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.4 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.

ASTM E1268-19 评定显微结构带状或定向程度的标准实施规程

1.1 This practice describes a procedure to qualitatively describe the nature of banded or oriented microstructures based on the morphological appearance of the microstructure. 1.2 This practice describes stereological procedures for quantitative measurement of the degree of microstructural banding or orientation. NOTE 1—Although stereological measurement methods are used to assess the degree of banding or alignment, the measurements are only made on planes parallel to the deformation direction (that is, a longitudinal plane) and the three-dimensional characteristics of the banding or alignment are not evaluated. 1.3 This practice describes a microindentation hardness test procedure for assessing the magnitude of the hardness differences present in banded heat-treated steels. For fully martensitic carbon and alloy steels (0.10–0.65 %C), in the asquenched condition, the carbon content of the matrix and segregate may be estimated from the microindentation hardness values. 1.4 This practice does not cover chemical analytical methods for evaluating banded structures. 1.5 This practice deals only with the recommended test methods and nothing in it should be construed as defining or establishing limits of acceptability. 1.6 The measured values are stated in SI units, which are regarded as standard. Equivalent inch-pound values, when listed, are in parentheses and may be approximate. 1.7 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. 1.8 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.
