1.1 本试验方法包括测定颜料悬浮度和将货架期油漆样品重新混合至适合预期用途的均匀条件的难易程度。 1.2 以国际单位制表示的数值应视为标准。括号中给出的值仅供参考。 1.3 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。 1.4 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====== 3.1 如果涂料配方或处理不当，可能会过度沉降。过度沉淀的油漆很难重新进入油漆系统，导致时间延迟或有价值的颜料留在桶中。本试验方法旨在评估加速试验方法引起的沉降程度 D1309 . 这种非常主观的评估方法与测试方法的变量相结合 D1309 提出了结果对规范遵从性有用性的问题。

1.1 This test method covers the determination of the degree of pigment suspension and ease of remixing a shelf-aged sample of paint to a homogeneous condition suitable for the intended use. 1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 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. ====== Significance And Use ====== 3.1 Paints, if not formulated or processed properly may settle excessively. Paint that settles excessively is difficult to reincorporate into the paint system causing time delays or valuable pigment being left in the drum. This test method is an attempt to evaluate the degree of settling caused by the accelerated Test Method D1309 . This very subjective method of evaluation in conjunction with the variables of Test Method D1309 raises questions as to the usefulness of the results for specification compliance.
