1.1 该试验方法包括两个测定煤油和航空涡轮燃料烟点的程序，一个手动程序和一个自动程序，这两个程序给出了不同精度的结果。 1.2 自动程序是裁判程序。 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 本标准并不旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者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====== 5.1 该试验方法提供了煤油和航空涡轮燃料在扩散火焰中相对产烟特性的指示。烟点与这种燃料的碳氢化合物类型组成有关。一般来说，燃料越芳香，火焰就越冒烟。高烟点表示燃料具有低烟产生趋势。 5.2 烟点在数量上与燃料燃烧产物的潜在辐射热传递有关。由于辐射热传递对燃气轮机燃烧室衬套和其他热段部件的金属温度有很大影响，因此烟点为燃料特性与这些部件寿命的相关性提供了基础。

1.1 This test method covers two procedures for determination of the smoke point of kerosene and aviation turbine fuel, a manual procedure and an automated procedure, which give results with different precision. 1.2 The automated procedure is the referee procedure. 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 This test method provides an indication of the relative smoke producing properties of kerosenes and aviation turbine fuels in a diffusion flame. The smoke point is related to the hydrocarbon type composition of such fuels. Generally the more aromatic the fuel the smokier the flame. A high smoke point indicates a fuel of low smoke producing tendency. 5.2 The smoke point is quantitatively related to the potential radiant heat transfer from the combustion products of the fuel. Because radiant heat transfer exerts a strong influence on the metal temperature of combustor liners and other hot section parts of gas turbines, the smoke point provides a basis for correlation of fuel characteristics with the life of these components.
