• 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

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.

TIP: For more detailed information please refer to
your Reference Guide.
3.1 Location
Please be aware that due to the heat emission (flash
point measuring range up to 405 °C) the PMA 5
needs to be located freely.
The device should not be exposed to draft. Draft
might falsify the measured flash point and affect the
control of the gas flame's function.
If you place several PMA 5 next to each other
please separate the single devices by using an ad-
equate shielding as otherwise through the ventila-
tion the devices affect each other in temperature
increase and flash point.
3.2 Putting into Operation
To ensure safe transportation, the PMA 5 is packed
in two pieces: a bottom part (control device) and an
upper part (multi-function head).
Insert the bolt of the multi-function head into the
guide of the column on the bottom part of the
PMA 5.
The pin of the bolt of the multi-function head now
rests in the right recess of the guide column (shown
on the right).
In this position of the multi-function head you can in-
sert or take out the test cup.
To bring the multi-function head into test position,
turn it to the left (clockwise) until the pin of the bolt
slides into lower position (shown in the photo on the
right).
To swivel the multi-function head back again, lift the
head slightly and turn it to the right (anti-clockwise)
until the pin rests safely in the upper position.
Connect the plugs of the step motor control and the
multi-detector at the rear of the instrument.
The plugs are different, so they can only be fitted
into the correct socket.
Connecting the gas tubes
Make sure the tube connections for gas supply and
fire extinguisher are gas-tight and secured in proper
manner (using hose clamps). Use only suitable
tubes and contact your local distributor in case of
safety doubts.
Do not exceed the pressure limits indicated at the
back plate and in this user manual (see Technical
Data on page 35).
3.3 Switching On
Before connecting to the mains please make sure
that the values on the device's rear side are set cor-
rectly for the existing mains voltage. If necessary
please adjust to the correct values.
The applicable voltage value needs to be set at the
change-over switch at the device's back side. Addi-
tionally, the device fuse has to be changed.
Connect the printer (option) to the printer interface
at the instrument’s side.
Before switching on the PMA 5 the printer has to be
connected to the USB port to make sure the head
row will be printed with the actual date after user log-
in. However, the header with the measuring data will
be printed out only after the first test was finished.
When using a gas ignition connect external gas sup-
ply to the back of the device with maximum inlet
pressure of 50 mbar.
Insert the multi-detector into the test insert (cup and
lid). Position test insert into the PMA 5 and turn the
multi-function head towards you so that the connec-
tion between multi-detector and stirrer is made.
Now you can switch on the PMA 5.
First only the green LEDs on the jog shuttle light up.

3.5.2 Gas Igniter
If you use the gas igniter, the electric igniter is used
as an auxiliary igniter in a special position at the
right side of the multi-function head.
The electric igniter now serves to ignite the gas
flame.
Fig. 3-4: Hose connection and gas valve
3.5.3 Connecting the External Gas Supply
The gas line or gas bottle has to be connected to the
rear side of the PMA 5 (we recommend the use of
propane / butane). Only use tubes which are admit-
ted for gas operation for the connection. The gas
pressure at the connection of the PMA 5 must be
50 mbar. Ensure that a pressure reducer is installed
as appropriate.
Fig. 3-5: Connection for external gas source
3.5.4 Adjusting the Gas Flame
After the external gas supply is connected to the in-
strument's rear side, the setting of the gas igniter
can be checked. The size of the gas flame has al-
ready been set at delivery. Before conducting the
first test we recommend to check this setting once
again.
TIP: When first connecting the gas, it will naturally
take a few minutes before the gas has passed
through the hoses and displaced the existing
air. To shorten this time it is possible to care-
fully open the gas valve at the device a bit
wider for a short moment only.
The size of the flame can be adjusted with the help
of the menu "Manual functions > Gas flame ad-
justment".

The gas valve on the PMA 5 to control the size of
the flame must never be closed with any force.
This would damage the valve in such a way that
it would not safely close any more.
Only close the valve hand-tight.
Connect the hose
of the gas igniter
Gas valve to
control the size of
the gas flame.
WARNING
Danger of fire
When connecting the plastic tubes, make sure
that they are placed away from hot surfaces and
ignition sources. Damage to the gas tubes could
lead to fire or explosions.

• Select the option "Gas flame on" to light the
flame.
• Select the option "Gas flame off" to extinguish
the flame.
Use the valve at the top right side of the device to
regulate the size of the flame.
The size of the gas flame has to be set between
3.2 mm and 4.8 mm in diameter according to the
standard.
SAFETY FUNCTION:
After about 1 min the magnetic valve switches off
automatically.
3.6 Filling in the Sample
According to the standard the sample is filled into
the cup up to the mark inside the cup. The tempera-
ture of the cup and sample shall be at least 18 °C or
32 °F below the expected flash point.
If you have filled too much sample into the cup, re-
move the excess using a syringe or similar device.
Samples with an expected high flash point and a
high heat expansion must be filled to a lower level.
Do not overfill the cup because of possible exces-
sive expansion behavior of the sample at high tem-
peratures. In case of unknown samples it is highly
recommended to perform a pre-test to determine of
a safe fill volume.
3.7 Fire Extinguisher System
The PMA 5 is equipped with an automatic fire extin-
guisher system which provides highest safety to the
user. In the event of a fire the system automatically
releases an inert gas over the lid shutter to extin-
guish the fire. For the correct function of the fire ex-
tinguisher system an inert gas (Nitrogen) source
with an outlet pressure of 6 to 12 bar is required.
NOTICE
The gas valve on the PMA 5 to control the size of
the flame must never be closed with any force.
This would damage the valve in such a way that
it would not safely close any more.
Only close the valve hand-tight.
WARNING
Danger of injury
Please use only tubes which are admitted for
gas-operation for the gas connection.
NOTICE
Always complete all steps to prepare the flash
point test before measuring and filling the sam-
ple into the cup.
If you are preparing the sample too early you
might have significant losses of volatile material.
This would lead to an erroneously high flash
point.
For the same reason make sure to store the
sample container air-tight, in dry conditions and
not above room temperature.
WARNING
Danger of malfunction
The sample should not come in contact with the
thermocouple for flash point detection at the
multi-sensor during the test otherwise flash point
indication can be affected.

3 Installation
18 H03IB005EN-C
Fig. 3-6: Fire extinguisher system
Connect the fire extinguishing gas line to the con-
nector at the back of the PMA 5 (we recommend the
use of Nitrogen).
Use only tubes with an inner diameter of 9 mm and
outer diameter of 15 mm which are admitted for gas
operation. The tube must withstand a maximum
pressure of 15 bar. Secure the tube with a hose
clamp.
The gas pressure at the connection of the PMA 5
must be 6 bar. Ensure that a pressure reducer is in-
stalled as appropriate.
Please refer to Fire Extinguisher Device and Fire
Signal Switch on page 37 for safety check and fur-
ther information about the fire extinguisher.
NOTICE
The fire extinguisher feature must be activated in
the device’s configuration! Without the activation
of the feature the fire extinguisher will not work.
Refer to Safety Configuration on page 26 for
details.
