ASTM E502-2007(2013) 采用密闭杯测定化学品闪点用ASTM标准的选择和使用的标准试验方法

　　

　　5.1x00a0;The flash point measures the response of the sample to heat and flame 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.

　　

　　5.2x00a0;As a result of physical factors inherent in the apparatus and procedure, the closed cup flash point does not necessarily represent the minimum temperature at which a material can evolve flammable vapors, and the absence of a flash point does not guarantee nonflammability (see Appendix X1 and Appendix X2).
