1.1 本试验方法涵盖了航空航天工业中遇到的几种常见气体在烃类液体中的平衡溶解度的估算。其中包括在288 K（59°F）下密度在0.63至0.90之间的石油馏分。溶解度可在228K温度范围内估算(−50°F）至423 K（302°F）。 1.2 该测试方法基于克劳修斯-克拉珀龙方程、亨利定律和理想气体定律，根据经验为每种气体的密度变化指定常数。 1.3 以国际单位制表示的数值应视为标准。括号中的值仅供参考。 1.4 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.5 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 5.1 气体溶解度的知识在气体压缩机的润滑中极为重要。它被认为是边界润滑的一个重要因素，在边界润滑中，溶解气体的突然释放可能会导致气蚀，甚至液膜崩溃。在液压油和密封油中，高压下溶解的气体在释放压力时会导致过度起泡。在航空用油和燃料中，起飞高度和巡航高度之间的压力差可能导致储存容器起泡，并中断流向泵的流量。

1.1 This test method covers the estimation of the equilibrium solubility of several common gases encountered in the aerospace industry in hydrocarbon liquids. These include petroleum fractions with densities in the range from 0.63 to 0.90 at 288 K (59°F). The solubilities can be estimated over the temperature range 228 K (−50°F) to 423 K (302°F). 1.2 This test method is based on the Clausius-Clapeyron equation, Henry's law, and the perfect gas law, with empirically assigned constants for the variation with density and for each gas. 1.3 The values stated in SI units are to be regarded as the standard. The values in parentheses are for information only. 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.5 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. ====== Significance And Use ====== 5.1 Knowledge of gas solubility is of extreme importance in the lubrication of gas compressors. It is believed to be a substantial factor in boundary lubrication, where the sudden release of dissolved gas may cause cavitation erosion, or even collapse of the fluid film. In hydraulic and seal oils, gas dissolved at high pressure can cause excessive foaming on release of the pressure. In aviation oils and fuels, the difference in pressure between take-off and cruise altitude can cause foaming out of the storage vessels and interrupt flow to the pumps.
