1.1 本试验方法涵盖了蜡乳液地板抛光剂在反复冷冻和解冻循环中的稳定性测定。观察到乳液的可能降解，并测量初始光泽的可能降低。 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）。本标准的使用者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》中确立的国际公认的标准化原则制定的。 ===意义和用途====== 3.1 本试验方法用于测定冷冻对蜡乳液地板抛光剂的影响。它可用于预测地板抛光剂在运输过程中或暴露在冷冻中时的稳定性，以及抛光剂是否因冷冻而损坏。

1.1 This test method covers the determination of the stability of wax emulsion floor polishes when these are exposed to repeated cycles of freezing and thawing. Possible degradation of the emulsion is observed and possible reduction of initial gloss is measured. 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 This test method is used to determine the effect of freezing on wax emulsion floor polishes. It may be used to predict the stability of a floor polish in transit or when exposed to freezing, and whether or not the polish is damaged by freezing.
