本文件规定了一种测定闪点在-30,0之间的可燃液体的手动和自动闭杯闪点的方法？C至75,0？°C。然而，该方法给出的精度仅对范围内的闪点有效？8,5？C至75,0？°C。 本文件不适用于水性涂料。 笔记？1？水性涂料可以使用ISO 3679[1]进行测试。 笔记？2？本试验在避免挥发性物质损失方面的重要性见9.1。 笔记？3？含有卤化化合物的液体会产生异常结果。 笔记？4？为手动仪器指定的温度计将测试温度上限限制为70,0？°C。 笔记？5？有关精密度的更多具体信息，请参见13.1。

This document specifies a method for the determination of the manual and automated closed cup flash point of combustible liquids having flash points between –30,0？°C to 75,0？°C. However, the precision given for this method is only valid for flash points in the range？8,5？°C to 75,0？°C. This document is not applicable to water-borne paints. NOTE？1？Water borne paints can be tested using ISO 3679^[1]. NOTE？2？See 9.1 for the importance of this test in avoiding loss of volatile materials. NOTE？3？Liquids containing halogenated compounds can give anomalous results. NOTE？4？The thermometer specified for the manual apparatus limits the upper test temperature to 70,0？°C. NOTE？5？See 13.1 for more specific information related to precision.
