acceptance of this instrument signifies that the
purchasing company and their agents, the end
users, are responsible for establishing all safety
and
health practices and assumes full
responsibility for safely using the K71000
Automatic PMCC Flash Point Analyzer.
2.3 Contaminated Samples
Samples contaminated with light ends (highly
volatile petroleum products) may light and
continue burning when the expected flash point
is set above the fire point of the material. In
addition, burning material may be ejected
through the ignition aperture in the test cup
cover. For this reason, the most recent updates
to ASTM D93 require a first application of
ignition at ambient temperature (<24°C below
EFP) and every 10°C. This helps when the
contaminant flashes at room temperature but
does not address all contamination situations.
Samples contaminated with water can bump and
eject hot and flammable material from the test
cup.
At all times, refrain from leaning or bending over
the test cup when the test is being carried out.
An unexpected flash can cause serious injury to
exposed body parts that are in close proximity to
the test area. Ejected material may cause
serious harm.
2.4 Safe Quick Test Method
The K71000 has a quick test option that begins
testing at ambient then heats the sample at an
accelerated pace while applying the igniter at
3°C increments. The detected flash is an
estimate of the expected flash point which is
then used in a subsequent run (under prescribed
standard test conditions) to safely arrive at the
flash point. The only disadvantage of this
screening method is that it requires additional
time and material to complete a safe analysis.
The Maximum Quick Test Temperature is 370
°C.
NOTE: The user must set this prescribed end
point prior to running a quick test. The set
maximum run temperature is solely at the user's
discretion.
We recommend this method of screening for
ALL samples.
2.5 Fire Detection / Suppression and Draft
Shield / Dome System
The K71000 comes standard with a fire
detection and inert gas fire suppression system.
This system is designed to flood the sample cup
area with an inert gas, extinguishing sample
based fires. The system is triggered when a
high temperature event melts the thermal fuse.
The open circuit condition triggers the flame
suppression system. The electronics are
extremely fast relying solely on electronic logic
(no software). The flame suppression system
also shuts off the ignition gas source, closes the
cup cover by de-energizing the motor, and de-
energizes the electric igniter if in use.
WARNING: Never operate the instrument
without the draft shield make it difficult to
inadvertently touch hot working surfaces.
2.6 Equipment Modification and
Replacement Parts
Any modification or alteration of this equipment
from that of factory specifications is not
recommended and voids the manufacturer
warranty,
product safety, performance
specifications, and/or certifications whether
specified or implied, and may result in personal
injury and/or property loss. Replacement parts
must be O.E.M. exact replacement equipment.
2.7 Chemical Reagents Information
Chemicals and reagents used in performing the
test may exhibit potential hazards. Any user
must be familiarized with the possible dangers
before use. We also recommend consulting the
Material Data and Safety Sheet (MSDS) on each
chemical reagent for additional information.
MSDS information can be easily located on the
internet at http://siri.uvm.edu or

2.8 Additional Important Safety Information
WARNING: As an important safety
precaution, NEVER use unregulated gas with
the K71000 Pensky-Martens Closed Cup Flash
Point Analyzer!
Use in an area that is adequately ventilated,
preferably with an exhaust tube / pipe to remove
