mixture with at least ninety-nine percent of its components
having flashpoints of 100°F (37.8°C), or higher, is not
considered a flammable liquid

absorption, spontaneous chemical change or retained heat from
manufacturing or processing
OR
– That can be readily ignited (and when ignited burns so
vigorously and persistently that it creates a serious hazard)
OR
– When tested by the method described in 16 CFR 1500.44,
ignite and burn with a self-sustained flame at a rate greater
than 1/10th of an inch per second along its major axis.
Flashpoint
The minimum temperature at which a liquid gives off an
ignitable concentration of vapor, when tested by any of the
following measurement methods:
• Tagliabue closed tester. Use this for liquids with a
viscosity less than 45 Saybolt Universal Seconds (SUS) at
100°F (37.8°C), that do not contain suspended solids and do
not tend to form a surface film under test. See American
National Standard Method of Test for Flashpoint by Tag Closed
Tester, Z11.24.1979 (ASTM D 56-79)
• Pensky-Martens closed tester. Use this for liquids
with a viscosity equal to, or greater than, 45 SUS at 100°F
(37.8°C) or for liquids that contain suspended solids or have
a tendency to form a surface film under test. See American
National Standard Method of Test for Flashpoint by
Pensky-Martens Closed Tester, Z11.7.1979 (ASTM D 93-79)
• Setaflash closed tester. See American National
Standard Method of Test for Flashpoint by Setaflash Closed
Tester (ASTM D 3278-78)
Organic peroxides, which undergo auto accelerating
thermal decomposition, are excluded from any of the flashpoint
measurement methods specified above.
