Flash point numbers sounds dangerously low but there is the saving =
grace
that they call for a source of ignition.
Basically, any easily burned liquid will have a flash point that will =
scare
you. Think about it - every car with a half tank of gas could =
potentially
take out a city block. here is some description of the testing method,
taken off the net from http://www.saybolt.nl/sdc/material/122.htm:
Mark 'the torch' Miller
Flash point and fire point (Cleveland open cup)=20
Equivalent standard methods:
- ASTM D 92
- IP 36
- ISO 2592=20
Significance
The Flash point measures the tendency of the sample to form a =
flammable
mixture with air under controlled laboratory conditions.
It is only one of a number of properties which must be considered =
when
assessing the overall flammability hazard of a material.
The flashpoint is used in shipping and safety regulations.
The firepoint measures the characteristics of the sample to =
support
combustion. This method can be used for temperatures as high as =
400=F8C.=20
Method
Increase the temperature rapidly at first and then at a slow =
constant
as the flashpoint is approached. A small flame is directed into the =
cup. The
test
flame at the proper temperature causes ignition of the vapor above =
the
sample. The fire point can be determined by continuing the test to a
temperature
at which the sample burns for at least 5 s.=20
