Fully Automatic Flash & Fire point Apparatus:
Determination of the Flash- and Fire-Point with Open Cup - Cleveland Method (automatic)
AS PER IS 1209: 1978
This flash point
and fire-point test method is a dynamic method and depends on definite
rates of temperature increases to control the precision of the method.
Its primary use is
for viscous materials having a flash point between 79°C (175°F) and
400°C (752°F) except fuel oils, to define the hazards of flammable and
combustible materials used in shipping and safety regulations.
The temperature of
the approximately 70 ml test specimen is increased rapidly at first and
then at a slower constant rate as the flash point is approached. At
specified intervals a test flame is passed across the cup, to measure
the tendency of the test specimen to form a flammable mixture with air
under controlled laboratory conditions.
| The flash point is the lowest liquid temperature at which application
of the flame causes the vapors of the test specimen of the sample to
ignite. |
To determine the fire-point, the test is continued until the
application of the test flame causes the test specimen to ignite and
sustain burning for a minimum of 5s. |
It is an automatic
flash and fire-point tester used to examine liquid as well as highly
viscous samples in the same instrument without any additional equipment.
For substances with unknown flash points, the APPARATUS
has a special search mode program. During the entire heating period,
the test flame is moved across the sample at suitable intervals. The
expected flash point of a specimen can thereby be found in a time
saving and economical manner.
Optional On demand:
When examining
highly viscous specimens, a preheating time and temperature are set in
order to warm-up and liquefy the sample to inserted temperature probe
without problem. Further a skimmer is removing the surface skin from
bituminous samples.
