The ASTM D1310-14 (2021) standard specifies a method for determining the flash point and ignition point of liquids using a Tiger open cup device. The method is suitable for determining the flash point and ignition point of liquids with a flash point between -18 and 165 ° C. Although the method has poor reproducibility for readily skinning or viscous paints and Resin solutions, heating can be continued to determine the ignition point by the label open cup method. This standard provides an important reference for the definition of flammability hazards of liquids, but is not applicable to describing fire hazards under actual fire conditions.
