ASTM D7215-08(2013)由美国材料与试验协会 US-ASTM 发布于 2008。
ASTM D7215-08(2013) 在中国标准分类中归属于: E31 燃料油。
4.1 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.
4.2 Flash point is used in shipping and safety regulations to define flammable and combustible materials. Consult the particular regulation involved for precise definitions of these classifications.
4.3 Flash point can indicate the possible presence of highly volatile and flammable materials in a relatively non-volatile or non-flammable material.
4.4 In cases where Test Method D2887 data are available, that is, for determination of boiling range distribution or calculation of other physical properties, this test method provides a calculation method for flash point without performing an additional analysis. Table 1 shows the ranges for the IBP, 5%, and 10% results for each equation.

该标准试验方法等效采用ASTM D86-1995,适用于测定所有发动机燃料、溶剂油和轻质石油产品的馏程。蒸馏装置有手工蒸馏(采用喷灯加热或电加热)和自动蒸馏,但有争议时,仲裁试验应采用手工蒸馏。如图所示,为采用电加热的手工蒸馏装置总装图。 蒸馏测定时,将100 mL试样在规定条件下进行蒸馏,系统观察温度计读数和冷凝液体积,并根据这些数据,进行计算和报告结果。 ...
仪器是用于测定石油产品常压馏程的自动蒸馏试验仪器,适用于按照GB/T 6536《石油产品常压蒸馏特性测定法》、GB/T 7534《工业用挥发性有机液体 沸程的测定》、ASTM D 86、ASTM D 850、ASTM D 1078等标准,对汽油、航空汽油、喷汽燃料、特殊沸点的溶剂、石脑油、柴油、馏分燃料、工业用挥发性有机液体及相似的石油产品进行蒸馏测定,是本公司推出的一款技术先进、使用方便、性价比高的自动蒸馏试验器...
