1.1 本试验方法涵盖了评估冻融循环对水基油墨和油墨载体性能影响的程序。 1.2 本试验基于涂层的类似标准试验；试验方法 D2243 . 1.3 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。 1.4 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====== 4.1 当水性油墨和油墨载体在寒冷天气下运输时，这些材料可能会经历冻融循环。这会损坏材料，使其无法使用。 4.2 与油墨或油墨载体处于稳定冷冻状态相比，冷冻和解冻循环会对水性油墨或油墨载体造成更大的损坏。

1.1 This test method covers a procedure for evaluating the effect of freeze-thaw cycling on the properties of water-based inks and ink vehicles. 1.2 This test is based on a similar standard test for coatings; Test Method D2243 . 1.3 The values stated in SI units are to be regarded as the standard. The values given 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 ====== 4.1 When waterborne inks and ink vehicles are shipped during cold weather, these materials may experience cycles of freezing and thawing. This can damage the material rendering it unusable. 4.2 Cycles of freezing and thawing can cause more damage to waterborne inks or ink vehicles than when the inks or ink vehicles are subjected to steady freezing.
