1.1 本试验方法包括照明用煤油燃烧特性的定性测定。( 警告 易燃的蒸汽有害。） 注1: 相应的能源研究所（IP）测试方法为IP 10，其特点是对煤油的灯芯炭形成趋势进行定量评估，而测试方法 D187 以煤油的定性性能评估为特征。这两种测试方法都使煤油受到比典型指定应用中更苛刻的操作条件的影响。 1.2 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。 1.3 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。 具体的警告语句出现在整个测试方法中。 1.4 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 由于该试验方法提供的信息在本质上主要是定性的，因此在煤油规范中参考该试验方法时，需要涵盖以下特征的特定限值: 5.1.1 测试持续时间:16 h是可理解的，除非另有规定； 5.1.2 试验期间火焰形状和尺寸的允许变化； 5.1.3 烟囱沉积物的可接受外观说明。

1.1 This test method covers the qualitative determination of the burning properties of kerosene to be used for illuminating purposes. ( Warning— Combustible. Vapor harmful.) Note 1: The corresponding Energy Institute (IP) test method is IP 10 which features a quantitative evaluation of the wick-char-forming tendencies of the kerosene, whereas Test Method D187 features a qualitative performance evaluation of the kerosene. Both test methods subject the kerosene to somewhat more severe operating conditions than would be experienced in typical designated applications. 1.2 The values stated in SI units are to be regarded as 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. Specific warning statements appear throughout the test method. 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 ====== 5.1 Since the information provided by this test method is largely qualitative in nature, specific limits covering the following characteristics are required in referring to this test method in specifications for kerosene: 5.1.1 Duration of the test: 16 h is understood, if not otherwise specified; 5.1.2 Permissible change in flame shape and dimensions during the test; 5.1.3 Description of the acceptable appearance of the chimney deposit.
