1.1 本规范描述了一种醇-羧酸混合物，称为微乳混合物。 1.1.1 警告- 微乳液混合罐应储存在为含氧和低闪点液体设计的设施和设备中。 1.2 将微乳混合料与燃油混合，以产生由反胶束组成的微乳试验燃油。 注1: 虽然目前没有微乳试验燃油的燃油标准，但开发微乳试验燃油的工作正在进行中。 注2: 可用于与微乳混合物混合的典型燃油是符合规范的燃油 D975 和 D396页 并且可能含有高达5%（按体积计）的生物柴油。 注3: 使用含有10%微乳混合料的试验燃料（使用B5作为基础燃料）进行试验，与B0基础燃料相比，未显示出对规定燃料特性的任何有害变化，但可能会影响微乳混合料浓度的测量。 1.2.1 微乳测试燃油（由该混合料制成）仅用于特定设备和车辆的测试和演示目的，这些设备和车辆适用于或已经配备了用于低闪点燃料和含氧燃料（如乙醇）的安全预防措施。最低安全预防措施可能包括阻火器和接地带。 注4: 与传统柴油相比，这种混合燃料的闪点较低，增加了储存和分配过程中的某些危险。 1.3 本规范中的任何内容均不得妨碍遵守可能更具限制性的联邦、州或地方法规。 1.4 以国际单位制表示的数值应视为标准值。国际单位制后括号中给出的值仅供参考，不被视为标准值。 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。

1.1 This specification describes an alcohol-carboxylic acid blend, referred to as the microemulsion blendstock. 1.1.1 Warning— The microemulsion blendstock should be stored in facilities and equipment designed for oxygenated and low flashpoint liquids. 1.2 The microemulsion blendstock is to be blended with fuel oils to produce a microemulsion test fuel oil that consists of inverse micelles. Note 1: While no fuel standard currently exists for a microemulsion test fuel oil, work to develop one is underway. Note 2: Typical fuel oils that could be used for blending with microemulsion blendstock are fuels that comply with Specifications D975 and D396 and may contain up to 5 % by volume biodiesel. Note 3: Testing with test fuels containing 10 % microemulsion blendstock using B5 as a base fuel did not show any detrimental changes to specified fuel properties relative to B0 base fuels, but can impair measurement of microemulsion blendstock concentration. 1.2.1 The microemulsion test fuel oil (to be made from this blendstock) is to be used for testing and demonstration purposes only in specific equipment and vehicles that are suited for or have been equipped with safety precautions for use with low flashpoint fuels and oxygenated fuels such as ethanol. Minimum safety precautions may include flame arrestors and grounding straps. Note 4: The low flash point of this blendstock relative to conventional diesel fuel increases certain hazards during storage and distribution. 1.3 Nothing in this specification shall preclude observance of federal, state, or local regulations, which may be more restrictive. 1.4 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered 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.
