other conditions. We assume the bath is well covered at this point. This is also
subject to company policy.
Flash Point: The point at which ignition may occur. The point shown may be
either the open or closed cup flash point. Refer to the flash point discussion in
Section 9.1.8, Safety.
Boiling Point: At or near the boiling point of the fluid the temperature stability
is difficult to maintain. Fuming or evaporation is excessive. Large amounts of
heater power may be required because of the heat of vaporization.
