1.1 本试验方法涵盖了乳化沥青中残留物的快速定量测定，给出了与试验方法类似的结果 D6934 , D6997 和 D7404 . 1.2 由于尚未制定本标准的精度估计，试验方法仅用于研究和信息目的。因此，本标准不应用于验收或拒收用于采购目的的材料。 1.3 以国际单位制表示的数值应视为标准。本标准不包括其他计量单位。 1.4 本标准的文本引用了提供解释材料的注释和脚注。这些注释和脚注（不包括表和图中的注释和脚注）不应视为本标准的要求。 1.5 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。 1.6 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 该试验方法可用于定量测定乳化沥青中的残留物。 注1: 本标准产生的结果质量取决于执行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 通常认为能够胜任和客观的测试、抽样、检查等。本标准的用户应注意遵守规范 D3666 单独使用并不能完全确保可靠的结果。可靠的结果取决于许多因素；遵循规范建议 D3666 或一些类似的可接受指导提供了评估和控制其中一些因素的方法。

1.1 This test method covers a quick and quantitative determination of residue in emulsified asphalts giving comparable results to Test Methods D6934 , D6997 , and D7404 . 1.2 Since a precision estimate for this standard has not been developed, the test method is to be used for research and informational purposes only. Therefore, this standard should not be used for acceptance or rejection of a material for purchasing purposes. 1.3 The values stated in SI units are to be regarded as the standard. No other units of measurement are included in this standard. 1.4 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. 1.5 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. 1.6 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 can be used for quantitative determination of residue in emulsified asphalts. Note 1: The quality of results produced by this standard is 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 guidance provide a means of evaluating and controlling some of those factors.
