4 Safety instructions
General information
Please read the instruction manual in full before
use and follow the safety instructions.
• Keep the instruction manual in a place where it can be ac-
cessed easily.
• Ensure that only trained staff use the device.
• Be sure to comply with all safety instructions, directives and
all matters of health, safety and accident prevention in the
workplace.
• Wear your personal protective equipment.
Work with the device
DANGER Oxygen as a compressed gas is ox-
idising; intensively aids combus-
tion; can react violently with flam-
mable 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 suit-
able gas cleaning system or ex-
traction system.
Please observe chapter “15 Tech-
nical data”.
If you are burning unknown sam-
ples, 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 deminer-
alised water (due to increased dan-
ger of corrosion)!
The C 6000 must be switched off
when you fit peripheral devices.
CAUTION When handling combustion sam-
ples, combustion residue and aux-
iliary 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 en-
suring the high measuring accura-
cy of the system. Observe the con-
ditions for the place of installation.
• The IKA C 6000 global standards/isoperibol calorimeter sys-
tem 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 recom-
mends 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 de-
composition vessel before each
combustion process (see operating
instructions C 6010/6012).
Risk of corrosion!
Substances with high halogen con-
tent must not be combusted in
the C 6010 decomposition vessel;
instead use the C 6012 decompo-
sition vessel.
NOTE Observe the operating instructions
for the decomposition vessels
C 6010/C 6012.
NOTE When using stainless steel cruci-
bles thoroughly check their condi-
tion after each experiment. If the
material gets thinner, the crucible
may catch fire and damage the de-
composition vessel. Crucibles must
not be used for more than 25 com-
bustions 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 operat-
ing 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 per-
formed or is performed incorrectly,
there is a risk the decomposition
vessel may burst or an uncon-
trolled 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 decomposi-
tion 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 experi-
ments 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 (in-
ternal 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 immedi-
ately 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. Oven-
dry 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).

Working mode: Adiabatic
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
6.2 Corrections
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).
