OAR 333-016-0050: Method for Determining Flashpoint of Extremely Flammable Contents of Self-Pressurized Containers

The apparatus used in the Tagliabue Open-Cup Flashpoint Apparatus as described in OAR 333-016-0035. Some means such as dry ice in an open container is used to chill the pressurized container. The container, the flash cup, and the bath solution of the apparatus (brine or glycol may be used) are chilled to a temperature of about 25°F below zero. The chilled container is punctured to exhaust the propellant. The chilled formulation is transferred to the test apparatus and tested in accordance with the method described in OAR 333-016-0035.
