1.1 本试验方法包括在40℃范围内测定航空涡轮燃料、柴油、煤油和相关产品的闪点 摄氏度至135度 °C通过小型闭杯装置。 1.2 本试验方法仅适用于在环境温度或接近环境温度以及在进行试验所需温度下为液体的均质材料。 1.3 本试验方法不适用于被微量高挥发性物质污染的液体。 1.4 该试验方法是一种动态方法，取决于一定的升温速率。这是许多可用的闪点方法之一，每种闪点测试方法，包括这一种，都是经验方法。 1.5 如果用户规范要求使用定义的闪点法，则在未获得比较数据和说明符同意的情况下，不得用本试验或任何其他方法代替规定的方法。 1.6 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。 1.7 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。 有关具体的危险说明，请参阅第节 7. 以及被测试产品的材料安全数据表。 1.8 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 闪点温度是测量试样在受控实验室条件下与空气形成易燃混合物的趋势的一种方法。这只是评估材料整体易燃性危险时必须考虑的众多特性之一。 5.2 运输和安全法规中使用闪点来定义 易燃的 和 易燃的 并对其进行分类。有关这些分类的精确定义，请参阅相关的特定法规。 5.3 本试验方法可用于测量和描述受控实验室条件下材料对热和试验火焰的响应特性，不得用于描述或评估实际火灾条件下材料的火灾危险或火灾风险。然而，本试验方法的结果可作为火灾风险评估的要素，该评估考虑了与特定最终用途火灾危险评估相关的所有因素。

1.1 This test method covers the determination of the flash point of aviation turbine fuel, diesel fuel, kerosine and related products in the temperature range of 40 °C to 135 °C by a small scale closed cup apparatus. 1.2 This test method is only applicable to homogeneous materials that are liquid at or near ambient temperature and at temperatures required to perform the test. 1.3 This test method is not applicable to liquids contaminated by traces of highly volatile materials. 1.4 This test method is a dynamic method and depends on a definite rate of temperature increase. It is one of many flash point methods available, and every flash point test method, including this one, is an empirical one. 1.5 If the user's specification requires a defined flash point method, neither this test nor any other method should be substituted for the prescribed method without obtaining comparative data and an agreement from the specifier. 1.6 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.7 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. For specific hazard statements, see Section 7 and the Material Safety Data Sheet for the product being tested. 1.8 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 The flash point temperature is one measure of the tendency of the test specimen to form a flammable mixture with air under controlled laboratory conditions. It is only one of a number of properties that must be considered in assessing the overall flammability hazard of a material. 5.2 Flash point is used in shipping and safety regulations to define flammable and combustible materials and classify them. Consult the particular regulation involved for precise definitions of these classifications. 5.3 This test method can be used to measure and describe the properties of materials in response to heat and a test flame under controlled laboratory conditions and shall not be used to describe or appraise the fire hazard or fire risk of materials under actual fire conditions. However, results of this test method may be used as elements of a fire risk assessment, that takes into account all of the factors that are pertinent to an assessment of the fire hazard of a particular end use.
