1.1 本试验方法涵盖了橡胶制品中使用的商业化学品的溶解度的实际试验。 1.2 这不是溶解度的真实测量，因为平衡不是从两个方面来实现的，即高温和低温。 1.3 试验方法表明，在试验条件下，所有成分在相互存在的情况下以及在样品中的比例下的总溶解度。 1.4 本试验方法不测量橡胶化学品在橡胶中的溶解度。 1.5 以国际单位制表示的数值应视为标准值。国际单位制后括号中给出的值仅供参考，不被视为标准值。 1.6 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。 1.7 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====== 4.1 本试验方法可用作原材料质量控制工具。

1.1 This test method covers a practical test for the solubility of commercial chemicals used in rubber products. 1.2 It is not a true measure of solubility, since equilibrium is not approached from both sides, that is, higher temperature and lower temperature. 1.3 The test method indicates the total solubility, under the conditions of the test, of all components in the presence of each other and in the proportions present in the sample. 1.4 This test method does not measure the solubility of a rubber chemical in rubber. 1.5 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered 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. ====== Significance And Use ====== 4.1 This test method may be used as a raw material quality-control tool.
