1.1 本试验方法涵盖了主要由半固体或液体沥青基、水和乳化剂组成的乳化沥青中残渣和油馏出物的定量测定。 1.2 以SI单位表示的值应被视为标准。本标准不包括其他计量单位。 1.3 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。 1.4 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》中确立的国际公认的标准化原则制定的。======意义和用途====== 4.1 本试验方法可用于乳化沥青中残渣和油馏出物的定量测定，用于规范验收、使用评价、控制和研究。该测试方法也可用于获得用于进一步测试的残渣和油馏出物。 附注1: 试验方法 D7403 和实践 D7497 是获得残留物进行进一步测试的低温选择。

1.1 This test method covers the quantitative determination of residue and oil distillate in emulsified asphalts composed principally of a semisolid or liquid asphaltic base, water, and an emulsifying agent. 1.2 The values stated in SI units are to be regarded as the standard. No other units of measurement are included in this standard. 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 ====== 4.1 This test method can be used for quantitative determination of residue and oil distillates in emulsified asphalts for specification acceptance, service evaluation, control, and research. This test method can also be used to obtain residue and oil distillate for further testing. Note 1: Test Method D7403 and Practice D7497 are low-temperature options for obtaining residue for further testing.
