1.1 本规程涵盖并提供了变性燃料乙醇与汽油混合料的体积混合说明，如用于含氧化合物混合的重新配方汽油混合料（RBOB）或用于含氧化合物混合的传统汽油混合料（CBOB）。 1.2 本规程不排除使用自动体积混合系统。 1.3 以国际单位制表示的数值应视为标准值。本标准不包括其他计量单位。 1.4 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。 1.5 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====== 5.1 通常，生产后将变性燃料乙醇添加到汽油混合料中。对于实验室测试类似于市场上可用成品燃料的样品而言，重要的是提供实验室实践，以标准化变性燃料乙醇和汽油混合物的制备。 5.2 实验室混合物应按体积制备，以产生与消费者使用的燃料类似的燃料。 5.3 适用时，混合物应符合CFR 40.80子部分D-重新配制汽油的要求。

1.1 This practice covers and provides instructions on making a volumetric blend of denatured fuel ethanol with gasoline blendstocks, such as a reformulated gasoline blendstock for oxygenate blending (RBOB) or a conventional gasoline blendstock for oxygenate blending (CBOB). 1.2 This practice does not preclude the use of automated volumetric blending systems. 1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this 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 ====== 5.1 Typically, denatured fuel ethanol is added to gasoline blendstocks after production. For laboratories to test a sample that is similar to the finished fuel available in the market, it is important to provide a laboratory practice that standardizes the preparation of a blend of denatured fuel ethanol and gasoline blendstock. 5.2 The laboratory blend shall be prepared volumetrically to yield a fuel similar to that produced for consumer use. 5.3 When applicable, blends shall meet requirements of CFR 40.80, Subpart D—Reformulated Gasoline.
