1.2 Special Safety Instructions
• PMA 5 has been developed as a testing device
for flash point testing. If PMA 5 is used for other
test media, including the testing of new or modi-
fied additives, it is the responsibility of the user
to determine in advance and prevent any risks
that could result from high temperatures. This
includes explosive reactions, which may occur
due to high temperatures. The forming of poten-
tially-toxic reactive products cannot be ruled out.
• The testing of highly explosive materials (such
as pyrotechnic or blasting substances) is gener-
ally not allowed. Have in mind that flammable
materials may generate explosive atmospheres.
Make sure to operate the instrument in safe
areas such as fume hoods with integrated
exhaust systems.

• Observe the stirrer movement. Wear a hair net
for protection to avoid injuries.
• Do not test strong acids due to the danger of
hydrogenic out gassing in reaction with the cup
material.
• Manipulation of the pressure hose is strictly
prohibited. Any resulting leaks can cause the
discharge of flammable fumes inside and out-
side of the device – DANGER OF EXPLOSION!
• A release of combustible liquid can only occur in
case of non-standards-compliant use of the
device. Please ensure the correct filling quantity
according to standard and do not overfill the
sample receptacle.
• The maximum sample fill level is marked at the
cup’s inside. Do not overfill the cup. Make sure
the fill volume corresponds to the expansion
coefficient and the maximum test temperature.
Reduce fill volume in order to prevent liquid
overflow.
• The parts of the instrument can become very hot
during the test run. Therefore, do not touch any
device components in the heating area, neither
during nor after the test run, with your unpro-
tected hand.
• The device is not suitable for warming up foods.
This device is only to be deployed for its
intended use.
Setup location
• PMA 5 is not an explosion-proof instrument and
therefore must not be operated in areas with risk
of explosion.
• Install PMA 5 only in a corrosion-free atmo-
sphere.
• When the instrument is set up, care should be
taken to choose an adequate distance from
sources of heat or smoke and from electrical or
magnetic disturbances, and that the device is
not subjected to excessive electrostatic dis-
charges (ESD). The surface of the workspace
must be level. In order to prevent influence of
the volume acquisition, the device is not allowed
to be subjected to any vibrations.
• The device undergoes testing for compliance
with threshold values of electromagnetic com-
patibility (EMC), as specified in the European

to the operating instructions, it may cause
disturbances in radio traffic.
• The instrument is only allowed to be connected
to a power supply, as specified on the device
and in the operating instructions.
• PMA 5 is an instrument with protective earth
connection class I. Proper earthing of the device
is to be ensured by on-site installation, accord-
ing to the normal rules and should be regularly
checked.
• Please ensure when laying the power cable that
it cannot be damaged by persons or objects
placed on it.
•In the zone where liquids are poured
(samples), there should be no power outlets.
Should it be necessary to have a power outlet in
the area where liquids are poured, there must
be a suitable local vent hood above the place
where the pouring occurs.
• Please undertake to ensure that because of its
radiating heat, PMA 5 stands alone and no flam-
mable objects are in the immediate vicinity.
Based on safety considerations, the placement
of the device should proceed (e.g. through build-
ing measures) in such a manner that improper
WARNING
Risk of fire
When testing samples without known flash point
special care must be taken to avoid the risk of a
fire in case of accidentally overheating the sam-
ple. If the flash point of the sample is below the
start temperature, a fire can occur.
• Always supervise flash point tests of samples
with unknown flash point, do not leave the
instrument unattended.
• Always select the lowest possible start tem-
perature when testing unknown samples.
Precool the sample.
• Avoid to set a too high maximum testing tem-
perature. Instead, you can run consecutive
tests raising the maximum testing tempera-
ture with each test.
• It is strongly recommended to run tests with
unknown flash point only on instruments with
fire extinguisher feature and connected inert
gas.
Further information on safe testing of such sam-
ples can be found in chapter Programming and
Performing a Test Run.

2 An Overview
2.1 Intended Use
The automatic flash point analyzer PMA 5 is used
for the empirical determination of the flash point of
combustible liquids in accordance with the stan-
dardized test procedures and standards:
• ASTM D93 A, B and C, ISO 2719 A, B and C,
JIS K2265 A, JIS K2265 B
These standards do not address all the safety con-
cerns (if any) associated with their use. The opera-
tor of the PMA 5 should establish the appropriate
safety and health practices before using the auto-
matic flash point analyzer PMA 5.
The flash point determination is an empirical meth-
od. It is therefore important to comply with the stan-
dard specifications as accurately as possible, both
in respect of the equipment and of the procedures.
The flash point of a liquid is used in transport and
safety provisions to define flammable and combus-
tible substances.
The flash point is one of several material properties
referred to in the determination of the overall fire risk
of a material.
The flash point is defined as the lowest temperature
of the liquid at which the vapor above the sample
ignites as a result of the introduction of the flame or
electric igniter.
The test procedures are standardized and laid down
in the above mentioned standards.
The measurement period is from approx. 30 to
60 min. depending on the flash point of the sample.
With manual flash point measurements, high re-
quirements are set of the laboratory technician car-
rying out the measurement, both in respect of
handling of the sample (avoidance of loss of volatile
components, precise observation of the flash point)
and in respect of the cleaning of the equipment.
In view of the complicated processes and handling
involved in manual measurement, Anton Paar
ProveTec has developed the automatic Pensky-
Martens flash point analyzer PMA 5. When using
the PMA 5 the operator’s task is to fill the test cup
with the sample, place it in the heating block and to
remove the test cup again once the measurement is
completed. It is necessary to pay attention to the
standard while preparing the sample.
Summary of the Pensky-Martens Test Method
Approx. 75 mL sample is heated at a slow constant
rate (5 to 6 °C/min) with continuous stirring in a
closed brass test cup of dimensions specified by the
standard method. The first test temperature is deter-
mined from the expected flash point entered by the
operator. When the first test temperature is
reached, the ignition source (the gas flame or the
electrical igniter) is applied by opening the shutter of
the test cup and dipping the igniter into the vapor
space at the top of the test cup. The igniter is sub-
sequently applied at the correct frequency until the
vapor above the sample the sample ignites. Stirring
is discontinued during application of the igniter.
You can also run a non-standard flash point test with
the PMA 5.
The Flash Point of petroleum products is the lowest
temperature, corrected to a barometric pressure of
101.3 kPa (760 mm Hg), at which the application of
an ignition source causes the vapors of a specimen
of the sample to ignite under specified test condi-
tions.
