ISO 2719:2016描述了使用Pensky-Martens闭杯测试仪测定可燃液体、含悬浮固体的液体、在试验条件下容易形成表面膜的液体、生物柴油和温度范围为40°C至370°C的其他液体闪点的三个程序A、B和C。 注意:对于某些混合物，未观察到规定的闪点；相反，试验火焰显著增大（不是光晕效应），试验火焰颜色从蓝色变为黄色- 橙色可能会出现。持续加热可能会导致测试杯外的蒸汽大量燃烧，并可能引发火灾。 注1:虽然从技术上讲，闪点高于40°C的煤油可以使用本国际标准进行测试，但根据ISO 13736测试煤油是标准做法。[5] 同样，润滑油通常根据ISO 2592[2]进行测试。 程序A适用于馏出燃料（柴油、生物柴油混合物、取暖油和涡轮燃料）、新燃料和新燃料- 使用不在程序B或C范围内的润滑油、油漆和清漆以及其他均质液体。 程序B适用于残余燃油、稀释残渣、使用过的润滑油、液体与固体的混合物、在试验条件下倾向于形成表面膜的液体，或在程序a的搅拌和加热条件下运动粘度不均匀的液体。 程序C适用于EN 14214[11]或ASTM D6751[13]等规范中规定的脂肪酸甲酯（FAME）。 ISO 2719:2016不适用于水性涂料和清漆。 注2:可使用ISO 3679[3]测试水性涂料和清漆。含有微量高挥发性物质的液体可使用ISO 1523[1]或ISO 3679进行测试。

ISO 2719:2016 describes three procedures, A, B and C, using the Pensky-Martens closed cup tester, for determining the flash point of combustible liquids, liquids with suspended solids, liquids that tend to form a surface film under the test conditions, biodiesel and other liquids in the temperature range of 40 °C to 370 °C. CAUTION - For certain mixtures no flash point, as defined, is observed; instead a significant enlargement of the test flame (not halo effect) and a change in colour of the test flame from blue to yellowish-orange can occur. Continued heating can result in significant burning of vapours outside the test cup, and can be a potential fire hazard. NOTE 1 Although, technically, kerosene with a flash point above 40 °C can be tested using this International Standard, it is standard practice to test kerosene according to ISO 13736.[5] Similarly, lubricating oils are normally tested according to ISO 2592[2]. Procedure A is applicable to distillate fuels (diesel, biodiesel blends, heating oil and turbine fuels), new and in-use lubricating oils, paints and varnishes, and other homogeneous liquids not included in the scope of Procedures B or C. Procedure B is applicable to residual fuel oils, cutback residua, used lubricating oils, mixtures of liquids with solids, liquids that tend to form a surface film under test conditions or are of such kinematic viscosity that they are not uniformly heated under the stirring and heating conditions of Procedure A. Procedure C is applicable to fatty acid methyl esters (FAME) as specified in specifications such as EN 14214[11] or ASTM D6751[13]. ISO 2719:2016 is not applicable to water-borne paints and varnishes. NOTE 2 Water-borne paints and varnishes can be tested using ISO 3679[3]. Liquids containing traces of highly volatile materials can be tested using ISO 1523[1] or ISO 3679.
