ASTM D1310 – Standard Test Method for Flash Point and Fire Point of Liquids by Tag Open-Cup Apparatus
Description:
Significance and Use
5.1 Flash point and fire point of a liquid are physical properties that may be used to define their flammability hazards. The flash point may be used to classify materials in government regulations.
Scope
1.1 This test method covers the determination by Tag Open-Cup Apparatus of the flash point and fire point of liquids having flash points between −18 and 165°C (0 and 325°F) and fire points up to 325°F.
1.2 This test method, when applied to paints and resin solutions that tend to skin over or that are very viscous, gives less reproducible results than when applied to solvents.
NOTE 1: In order to conserve time and sample, the fire point of a material may be determined by the Tag Open-Cup Method by continuing the heating of the specimen to its fire point. Fire points may also be determined by Test Method D92, which should be used for fire points beyond the scope of this test method.
1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
