1.1 乳化沥青通常会因冻结温度而受损，但特殊配方的材料有望通过这一做法。 1.2 以SI单位表示的值将被视为标准值。本标准不包括其他计量单位。 1.3 本标准的正文参考了提供解释材料的注释和脚注。这些注释和脚注（不包括表格和图表中的注释和脚注）不应被视为标准的要求。 1.4 本标准并不旨在解决与其使用相关的所有安全性问题（如果有）。本标准的使用者有责任在使用前建立适当的安全、健康和环境实践并确定法规限制的适用性。 1.5 本国际标准是根据《关于制定国际标准的原则的决定》中确定的国际公认的标准化原则制定的世界贸易组织技术性贸易壁垒委员会发布的指南和建议。 ======意义和用途====== 3.1 某些希望在不太理想的天气条件下使用、储存或运输乳化沥青的机构可能要求产品在经受-18°C的温度后保持均匀（未破碎）。 附注1: 本标准产生的结果的质量取决于执行该程序的人员的能力以及所用设备的能力、校准和维护。符合规范标准的机构 D3666 通常被认为能够胜任和客观的测试、取样、检查等。本标准的使用者应注意符合规范 D3666 单独并不能完全确保可靠的结果。可靠的结果取决于许多因素；遵循规范的建议 D3666 或者一些类似的可接受的指南提供了评估和控制这些因素中的一些的方法。

1.1 Emulsified asphalt is normally damaged by freezing temperatures, but specially formulated materials are expected to pass this practice. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.3 The text of this standard references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard. 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 ====== 3.1 Certain agencies who desire to use, store, or transport emulsified asphalt under less than ideal weather conditions may require that the product remain homogeneous (unbroken) after being subjected to a temperature of −18 °C. Note 1: The quality of the results produced by this standard are dependent on the competence of the personnel performing the procedure and the capability, calibration, and maintenance of the equipment used. Agencies that meet the criteria of Specification D3666 are generally considered capable of competent and objective testing, sampling, inspection, etc. Users of this standard are cautioned that compliance with Specification D3666 alone does not completely ensure reliable results. Reliable results depend on many factors; following the suggestions of Specification D3666 or some similar acceptable guideline provides a means of evaluating and controlling some of those factors.
