Work with the device
DANGER
Oxygen as a compressed gas is oxidising; intensively aids combustion; can react violently with flammable materials.
Observe the relevant points of
danger shown in Fig. 4.
Combustion gases are hazardous
to health, therefore the venting
hose must be connected to a suitable gas cleaning system or extraction system.
Please observe chapter “15 Technical data”.
If you are burning unknown samples, leave the room or keep well
away from the calorimeter.
Do not use oil or grease!
The IKA C 6000 global standards/
isoperibol calorimeter must not be
used for testing explosive samples.
CAUTION
Do not use distilled or demineralised water (due to increased danger of corrosion)!
The C 6000 must be switched off
when you fit peripheral devices.
CAUTION
When handling combustion samples, combustion residue and auxiliary materials, please observe the
relevant safety regulations. The
following materials, for example,
could pose a risk:
– corrosive
– highly flammable
– explosive
– bacteriologically contaminated
– toxic.
NOTE
A constant ambient temperature is
an important requirement for ensuring the high measuring accuracy of the system. Observe the conditions for the place of installation.
• The IKA C 6000 global standards/isoperibol calorimeter system may be used only in conjunction with the decomposition
vessels C 6010 or C 6012 (Chapter 15 Technical data).
• Do not operate the device in explosive atmospheres, in the
presence of hazardous materials or under water.
• Please observe the relevant regulations when handling oxygen.
• When operating with tap water/from a tap, IKA
recommends that you use a standard water stop valve in the water
supply line.
• At the end of the work period, close the main valve for the
oxygen supply.
• Only change the main fuse when you have unplugged the
mains power supply.
Decomposition vessel
WARNING
Perform a leakage test on the decomposition vessel before each
combustion process (see operating
instructions C 6010/6012).
Risk of corrosion!
Substances with high halogen content must not be combusted in
the C 6010 decomposition vessel;
instead use the C 6012 decomposition vessel.
NOTE
Observe the operating instructions
for the decomposition vessels
C 6010/C 6012.
NOTE
When using stainless steel crucibles thoroughly check their condition after each experiment. If the
material gets thinner, the crucible
may catch fire and damage the decomposition vessel. Crucibles must
not be used for more than 25 combustions for safety reasons.
• Once the pressure test has been performed, a release code
can be entered to enable the decomposition vessel to be used
for further measurements (see decomposition vessel operating instructions). The warning message will then disappear.
• Please observe the maximum pressure for filling with oxygen
(Chapter “15 Technical data”). Check the set pressure on the
pressure reducer of your oxygen supply.
8
Maintenance
DANGER
If the maintenance, and especially
the pressure testing, is not performed or is performed incorrectly,
there is a risk the decomposition
vessel may burst or an uncontrolled internal fire may occur at
the electrodes which could burn
away the seals (oxyacetylene torch
effect), thus posing a risk to life
and limb.
NOTE
We recommend that you send the
pressure vessel to our factory for
inspection, and if necessary, repair
after 1000 tests or after one year
or sooner depending on use.
• The declaration of conformity becomes invalid if mechanical
modifications are carried out to the experiment autoclaves or
if tightness can no longer be guaranteed as a result of major
corrosion (e.g. pitting by halogens).
• Perform servicing work only when the equipment is
depressurised.
• Tubes and screwed joints for oxygen, and all seals on the
decomposition vessel must be kept free of grease.
• The condition and function of the seals must be checked and
ensured by way of a leakage test.
• In particular the threads on the pressure vessel and the union
nut are subject to considerable stress and must therefore be
checked regularly for wear.
• To prolong the life of wearing parts (o-rings, seals, etc.) we
recommend that you always work with a water trap in the
decomposition vessel.
• Contact the IKA Maintenance Department to perform the
pressure test. Comply with the safety instructions in this
respect.
• If the appliance is not going to be in operation for a long
period of time, it is advisable to completely empty the
calorimeter's water circulation. Likewise, the water must be
drained out before transportation.
• Please observe the maximum energy input in the decomposition vessel (Chapter “15 Technical data”).
• Decomposition vessels are experiment autoclaves and must
be tested by a technical expert after every use.
• Individual use is understood here to include a series of experiments performed under roughly the same conditions in terms
of pressure and temperature. Experiment autoclaves must be
operated in special chambers.
• The decomposition vessels must undergo repeated tests (internal tests and pressure tests) performed by the technical
expert. The frequency of these tests is to be determined by
the operator on the basis of experience, type of operation
and the material used in the decomposition vessel.
Pressure vessel
CAUTION
Only technical experts may
perform pressure tests and
maintenance work on the
pressure vessel.
• National directives and laws must be observed for
operating pressure vessels!
• Anyone operating a pressure vessel must keep it in a
proper condition, operate it properly, supervise it, carry
out the necessary maintenance and repair work immediately and implement the safety measures required in the
circumstances.
• Pressure vessels must not be used if they have defects
which could pose a risk to staff or third parties.
Permitted media
DANGER
If the burning behaviour of a
material is unknown, it must
be tested before combustion
in the decomposition vessel
(risk of explosion).
Benzoic acid may only be
combusted in its pressed form!
Flammable dust and powder
must be first pressed. Ovendry dust and powder such as
splints, hay, straw etc. explode
when combusted! Always wet
these materials first!
WARNING
Highly flammable liquids with
a low vapour pressure (e. g.
tetramethyl dihydrogen
disiloxane) must not directly
touch the cotton thread!
NOTE
When burning substances
containing metals, ensure that
the total energy input is not
exceeded.

5 Correct use
5.2 Area of use
- laboratories - schools - universities
The device is suitable for use in residential areas and all other areas.
The safety of the user cannot be ensured:
• If the device is used in conjunction with accessories not
supplied or recommended by the manufacturer!
5.1 Use
The IKA C 6000 global standards/isoperibol calorimeter system is
used for calorific value determination of solid and liquid substances.
This is done by placing a known quantity of a substance in a
decomposition vessel which is surrounded by a water bath.
5.3 Recommended method of operation in working mode
NOTE
The working mode temperature
should always be in the room
temperature range (+/- 2 °C) for
precise measurements.
1. Read the operating instructions and get to know the device.
2. Check that your peripheral devices are compatible with the
calorimeter (Chapter 11.3 Modules).
3. Select an appropriate place of installation (Chapter 8.1 Place
of installation) and commission the calorimeter (Chapter 10
Commissioning).
4. Select a working mode to suit the ambient temperature and
your requirements. In dynamic mode in particular, too great a
difference between the selected working mode temperature
and room temperature has a direct effect on the measuring
accuracy of the device. Set the corresponding cooling water
temperature (Chapter 15 Technical data).

The calorimetric decomposition vessel is ignited in a vessel
filled with water (inner vessel), which in turn is in an insulating
cover filled with water (outer vessel). No energy exchange
takes place between the inner vessel with decomposition
vessel and the outer vessel. For details, please consult the
relevant international standards (e.g. DIN 51900-3).
Working mode: Isoperibol:
The calorimetric decomposition vessel is ignited in a vessel
filled with water (inner vessel), which in turn is in an
insulating cover filled with water (outer vessel). A specified
energy exchange takes place between the inner vessel with
decomposition vessel and the outer vessel. For details, please
consult the relevant international standards (e.g. DIN 51900-
2).
Dynamic working mode:
A quick measuring mode developed by IKA. Its procedure
and results are not subject to international standards.
5. Register the decomposition vessel during initial commissioning
(Chapter 11.2 Decomposition vessel).
6. Switch the device to run hot for approx. 1 hour before
starting measurements. To achieve accurate measurements
you need a device that is adjusted to its ambient temperature
(Chapter 10 Commissioning).
7. Every decomposition vessel that you use must be calibrated
in the relevant working mode (adiabatic/isoperibol/dynamic
22 °C; 25 °C; 30 °C) during commissioning. This is done
by burning a calibration substance with a known calorific
value - generally benzoic acid (Chapter 6.1 Determining the
calorific value). For the number of calibrations and evaluation
required, see the relevant standards. You can test the stability
of the measurements through control calibrations at regular
intervals.
8. Select a working mode. If you are working in adiabatic mode,
you must carry out an adjustment at the relevant operating
temperature (22 °C; 25 °C; 30 °C). Observe the Adjustment
instructions (Chapter 6.5 Adjustment). An adjustment allows
you to automatically determine correct internal parameters
for implementing the adiabatic principle.
With the C 6000 global standard you can now carry out
adiabatic, isoperibol and dynamic measurements at specified
working temperatures, and with the C 6000 iso you can carry out
isoperibol and dynamic measurements at the specified working
temperatures. For adaptation to individual laboratory tasks, use
original IKA consumables and accessories.
The calorific value of the sample can then be calculated from the
resulting increase in temperature, the sample mass and the known
thermal capacity of the overall system.
Intended use: Tabletop device
• If the device is not used for the intended purpose as specified
by the manufacturer.
• If modifications are made to the device or the PCB by third
parties.

6 Useful information
The decomposition vessel C 6010/C 6012 is manufactured in
accordance with the directive for pressure equipment
2014/68/EU. This is indicated by the CE symbol with the ID number
of the notified body. The decomposition vessel is a category III
pressure device. The decomposition vessel was subjected to an
EC prototype test. The declaration of conformity confirms that
this decomposition vessel corresponds to the pressure device
described in the EC prototype test certificate. The decomposition
vessel has undergone a pressure test with the test pressure of

Due to the nature of the system a combustion test does not just
produce the combustion heat of the sample, but also heat from
external energy.
This can fluctuate considerably in relation to the heat quantity of
the fuel sample.
33 MPa and a leakage test with oxygen at 3 MPa. Some materials
tend to explode when combusted (e.g. due to formation of
peroxide), which can cause the decomposition vessel to crack.
Furthermore, toxic combustion residue in the form of gases, ashes
or condensation, for example, is possible in the inner wall of the
decomposition vessel.
You can obtain a copy of the Directive for pressure equipment
2014/68/EU from Beuth Verlag.
6.1 Determining the calorific value
The specific calorific value of the sample is calculated from:
• Weight of fuel sample
• Thermal capacity of the calorimeter system (C-value)
• Temperature increase of water in the calorimeter system
For complete combustion the decomposition vessel of the
calorimeter system is filled with pure oxygen (quality 3.5). The
pressure of the oxygen atmosphere in the decomposition vessel
should be set to 30 bar (max. possible is 40 bar). To precisely
determine the calorific value of a material the combustion needs
to take place under specifically defined conditions. The relevant
standards are based on the following assumptions:
• The temperature of the fuel before combustion depends on
the set start temperature between 20 °C and 30 °C.
• The water contained in the fuel before combustion and
the water formed whilst combusting the hydrogenous
compounds of the fuel is in fluid form after combustion.
• Oxidation of the air nitrogen has not take place. The
gaseous products after combustion include oxygen,
nitrogen, carbon dioxide, sulphur dioxide and the
oxidation products of the sample.
• Solid materials may form (e.g. ashes).
In many cases, however, not just the combustion products referred
to in the standards are produced. In such cases the fuel sample
and the combustion products must be analysed, providing data
for revised calculations.
The standard calorific value is then calculated from the measured
calorific value and the analysis data.
The calorific value Ho is calculated from the quotient of the quantity
of heat released during complete combustion of a solid or liquid
fuel and the weight of the fuel sample. The aqueous compounds
of the fuel must be present after combustion in liquid form.
The formula for the calorific value is:
Ho = (CV * dt – Qext) / m
Ho Calorific value
m Mass of the sample
dt Measured and corrected increase in temperature
Qext All external energy originating from the ignition wire,
the ignition aids, the combustion aids and the formation
of acids
CV C value (thermal capacity) of the calorimeter
The heat value Hu is the same as the calorific value, minus the
condensation energy of the water contained in the fuel and
formed through combustion.
The heat value is the more important parameter from a technical
point of view because in all major, technical applications only the
heat value can be evaluated in terms of energy.
The bases of calculation for the calorific and heat value can be
found in the relevant standards (e. g.: DIN 51 900; ASTM D 240;
ISO 1928).

The combustion heat of the cotton thread which ignites the sample

6.3 Note on the sample
DANGER
If you are burning unknown
samples, leave the room or keep
well away from the calorimeter.
WARNING
Risk of corrosion!
Substances with high halogen
content must not be combusted
in the C 6010 decomposition
vessel; instead use the C 6012
decomposition vessel.
NOTE
To prolong the life of wearing
parts (o-rings, seals, etc.) we
recommend that you always work
with a water trap.
The IKA C 6000 global standards/isoperibol calorimeter system
is a high-precision measuring instrument used for routinely
determining the calorific value of solid and liquid substances.
However exact measurements are only possible when the
individual test steps are carried out carefully. For this reason the
procedure must be followed precisely.
A few points should be noted in respect of the substances to be
combusted:
• Normally solid combustion substances in powder form can
be combusted directly. Materials which combust quickly (e.g.
benzoic acid) must not be burnt loose. Benzoic acid may
only be combusted in its pressed form! Flammable dust and
powder must be first pressed. Oven-dry dust and powder
such as splints, hay, straw etc. explode when combusted!
Always wet these materials first! Highly flammable liquids
with a low vapour pressure (e.g. tetramethyl dihydrogen
disiloxane) must not directly touch the cotton thread!
• Highly flammable substances tend to spray. Such substances
must be pressed into tablets before combustion. The IKA
pelleting press C 21, for example, is suitable for this task.
• Most fluid substances can weighed out directly into the
crucible. Liquids that are cloudy or that have water that
may separate must be dried or homogenised before being
weighed out. The water content of these samples must be
determined.
• Highly volatile substances are poured into combustion
capsules (gelatine capsules or acetobutyrate capsules, see
Accessories) and combusted together with the capsules.
• For substances that are dicult to ignite or low in calories, use
the burning aid (see accessories). Before filling the capsule or
the combustion bag with the substance to be determined,
weigh them to calculate the extra external energy added by
the burning aid from the weight and the calorific value. This
must be taken into account in QExtern2. You should keep the
amount of burning aid used to a minimum.
6.2.1 Acid correction
Virtually all of the materials to be studied contain sulphur and
nitrogen. Under the conditions in calorimetric measurements,
sulphur and nitrogen combust to SO
2
, SO3 and NOx. Together with
the water from combustion and moisture, sulphuric and nitric acid
as well as heat of solution are produced. In order to obtain the
standard calorific value, the influence of the heat of solution on
the calorific value is corrected.
To achieve a specified end state and to record all acids quantitatively,
distilled water or another appropriate absorbing liquid is placed
in the decomposition vessel in advance before the experiment
in accordance with the applicable standards. The combustion
gases form acids with this absorption liquid and the combustion
water. The calibration of the system must have been performed in
accordance with the instructions!
After the combustion the decomposition vessel is thoroughly
flushed with distilled water to collect the condensate that has
been deposited in the inner wall of the vessel as well. The solution
produced in this way can now be examined with appropriate
peripheral devices to detect its acid content. For more detailed
information contact IKA or an authorised dealer.
into the crucible with the sample. The additional heat quantity can
be determined from the weight of the burning aid and its known
specific calorific value. You must correct the test result by this heat
quantity.
12
6.4 Complete combustion
NOTE
If there is any unburnt residue, the
test must be repeated.
It is essential that the sample fully combusts to ensure correct
determination of the calorific value. After each experiment check
the crucible and all the solid residue for signs of incomplete
combustion.
Complete combustion is not guaranteed for materials with a
tendency to spray.
6.5 Adjustment (only IKA C 6000 global standards)
NOTE
If the device is to be operated in
adiabatic function, prior adjustment in the respective temperature range (22 °C, 25 °C or 30 °C) is
necessary.
Adjustment must be performed in the following cases:
• When first commissioning the calorimeter and when its place
of installation has been changed.
• If the measuring times for adiabatic measurements are
regularly in excess of 15-20 minutes.
• If adiabatic measurements are frequently aborted because the
time limits for the pre-trial or main trial have been exceeded.
Procedure for adjustment:
• In the menu select “Settings, Measurement settings, Adiabatic
working mode”.
• The adjustment starting temperature is preset by selecting
the working mode/temperature range.
• Start the adjustment by selecting the selection field r (e.g.
Adjustment 25 °C). Insert the decomposition vessel (without
sample).
• Follow the instructions.
• Adjustment starts automatically and is completed within
approx. 1 hour. After the adjustment has been successfully
completed the adjustment value appears as an increase in
temperature in the measurement record for the measurement
that was performed and is automatically adopted as a system
parameter.
• You can see the adjustment value under the menu item
“Information adjustment”.
After successful completion of adjustment the device automatically
changes the mode of operation to the corresponding adiabatic
mode.

6.6 Calibration
NOTE
Regular calibration is vital to
maintaining measurement accuracy.
To guarantee accurate and reproducible measurement results,
the calorimeter system is calibrated after initial start-up, after
maintenance work, after parts are replaced and at specified time
intervals. During calibration the thermal capacity of the calorimeter
system is revised.
To this end, a specified quantity of a reference substance is
burned in the IKA C 6000 global standards/isoperibol under
test conditions. As the calorific value of the reference substance
is known, after it has been burnt it is possible to calculate the
thermal capacity on the basis of the temperature increase of the
calorimeter system. The reference substance for calorimetry at an
international level is benzoic acid, as per the National Bureau of
Standards (NBS-Standard Sample 39 J) with guaranteed calorific
value.
The thermal capacity is derived from the formula for the calorific
value (Chapter 6.1 Determining the calorific value):
CV = (Ho * m + Qext) / dt
Depending on the standard used, determination of the thermal
capacity may require performance of several measurements.
Using various statistical criteria the average value is calculated and
is used as the thermal capacity for subsequent determinations of
calorific values.
For more detailed information on calibration, please see the
relevant standards. If the IKA C 6000 global standards/isoperibol
is operated with several decomposition vessels, you will need to
determine the heat capacity of the system for each decomposition
vessel. The parts of the decomposition vessel must not be replaced.
In addition the thermal capacity depends to a small extent on
the measurement procedure used. The thermal capacity must be
determined for each measurement procedure that is used.
Note on calibrations
The calibration must be carried out under the same conditions as
the subsequent tests. If substances are used in combustion tests
(e.g. distilled water or solutions), you must use exactly the same
amount of this substance for calibration.
For determination of calorific values the increase in temperature
must be about as great as for the calibration (e.g. g.: 2 tablets =
approx. 1 g benzoic acid =˜ 3 K). The optimum sample quantity
must be determined by several trials where necessary.
Materials which are dicult to ignite (materials with a high mineral
content, low caloric materials) can often only be fully combusted
using burning aids such as combustible crucibles, combustible
capsules or combustible bags (Chapter 14.2 consumables).
It is also possible to use liquid burning aids such as paran oil.
The ignition aids (e.g. cotton thread) must also burn completely.

8 Setting up and assembly
8.1 Place of installation
NOTE
A constant ambient temperature is
an important requirement for ensuring the high measuring accuracy of the system. Observe the conditions for the place of installation.
• No direct solar radiation
• No draughts (e.g. beside windows, doors, air conditioning)
• Nucient distance from radiators and other heat sources
• the minimum distance between the wall and the back of the
device must not be less than 25 cm.
• Laboratory additions such as shelves, cable ducts, ring lines
etc. must not be build above the system.
• The room temperature must remain constant.
• The system must be installed on a level surface.
For operation of the system the following must be available at the
place of installation:
• A power supply corresponding to the type plates of the
system components,
• An oxygen supply (99.95 % pure oxygen, quality 3.5; pressure
3 MPa) with pressure gauge.
There must be a shut-off device for the oxygen supply. Observe the
instructions for oxygen (Chapter 4 Safety instructions).
8.2 Assembly of the attachments
8.2.1 Condenser/thermostat
CAUTION
Do not use distilled or demineralised
water (due to increased danger of
corrosion)!
In normal operation the discharge
hose at the “EMPTY” connection
(Fig. 2, 12) must not be inserted.
Make sure the filter casing is
always securely closed.
NOTE
Observe the operating instructions
for the condenser/thermostat.
Tap water of drinking quality is
recommended. Mix in the water
bath additive supplied (max. 1 ml
for 4-5 L of water). This improves
the usable life of the water.
IKA recommends that you use
the system with the recirculating
condenser RC 2 at a speed of
2800 1/min (place of installation
downstream of the C 6000:
32001/min).
1. Insert the inflow pipe into the “IN” port until it clicks home in
the “IN” inlet (Fig. 2, 10).
2. Connect the other end of the pipe to the “OUT” port of the
condenser (water pressure max 1.5 bar).
Insert the return pipe into the “OUT” port until it clicks home
(Fig. 2, 11) and connect the other end of the pipe to the “IN”
port of the condenser.
The “EMPTY” connection is intended only for emptying the
device, e.g. for transport purposes (Chapter 12.1.3 Emptying
water).
