Safety instructions
Read the operating instructions in full before
starting up and follow the safety instruc-
tions.
Keep the operating instructions in a place where
they can be accessed by everyone.
Ensure that only trained staff work with the device.
Follow the safety instructions, guidelines, occupa-
tional health and safety and accident prevention
regulations.
The IKA®C 6000 global standards/isoperibol calo-
rimeter system may be used only in conjunction
with the decomposition vessels C 6010 or C 6012
for determination of the calorific values of solid
and liquid substances to national and international
standards (such as DIN 51900, BS 1016 T5, ISO
1928, ASTM 5468, ASTM 5865 and ASTM 4809).
The maximum extra energy added to the decom-
position vessel must not exceed 40,000 J (select
the test mass accordingly). The permitted operat-
ing pressure of 230 bar (23 MPa) must not be
exceeded. The maximum permitted operating tem-
perature must not exceed 50 °C.
When burning substances containing metals, en-
sure that the maximum energy input is not ex-
ceeded!
Only fill the decomposition vessel with oxygen to a
maximum pressure of 40 bar (4 MPa). Check the
pressure setting on the pressure reducer for your
oxygen supply. Perform a leakage test before each
combustion process (see section „Leaktightness
testing“).
Some materials tend to explode when combusted
(e.g. due to formation of peroxides), which could
cause the decomposition vessel to crack. The IKA®
C 6000 global standards/isoperibol calorim-
eter may not be used for testing explosive
samples.
If the burning behaviour of a material is unknown,
it must be tested before combustion in the decom-
position vessel (risk of explosion). If you are burn-
ing unknown samples, leave the room or keep
your distance from the calorimeter.
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 dihy-
drogen disiloxane) must not directly touch the cot-
ton thread!
Furthermore, toxic combustion residue in the form
of gases, ashes or condensation, for example, is
possible in the inner wall of the decomposition
vessel.
Observe the accident prevention
requirements applicable to the
activity and the work station.
Wear your personal protective equipment.
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
Please observe the relevant regulations when
handling oxygen.
Warning: oxygen as a compressed gas is oxidising;
intensively aids combustion; can react violently
with flammable materials.
Do not use oil or grease!
Tubes and screwed joints for oxygen must be kept
free of grease.
Combustion gases are
hazardous to health,
therefore the venting
hose must be connected to a suitable gas
cleaning system or extraction system.
At the end of the work period, close the main
valve for the oxygen supply.
Perform servicing work only when the equipment
is depressurised.
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.

We recommend that you send the decom-
position vessel to our factory for inspection,
and if necessary, repair after 1000 tests or
after one year or sooner depending on use
A pressure test must be performed after a decom-
position vessel has reached or exceeded the re-
commended number of ignition cycles. Once the
pressure test has been performed a release code
can be entered to enable the decomposition ves-
sel to be used for further measurements (see the
sections “Maintenance of the Decomposition Ves-
sel” and “Inputting a Service Code”).
The warning message will then disappear!
Note: You can then continue to use the device /
decomposition vessel.
Contact the IKA®Service Department to perform
the pressure test. Comply with the safety instruc-
tions in this respect. The user will be given specific
instructions on the relevant screen.
For the purposes of these operating instructions a
technical expert is someone
1. who guarantees to conduct the tests properly
on the basis of his training, knowledge and
experience gained through practical work,
2. who is suciently reliable,
3. who is not subject to any instructions in terms
of the test activity,
4. who has suitable test equipment if necessary,
5. who can provide appropriate proof of the re-
quirements listed in 1.
National directives and laws must be obser-
ved for operating pressure vessels!
Anyone operating a pressure vessel must keep it
in a proper condition, operate it properly, super-
vise 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.
The decomposition vessel is manufactured in ac-
cordance with the directive for pressure equip-
ment 97/23/EC. This is indicated by the CE sym-
bol with the ID number of the notified body. The
decomposition vessel is a category III pressure
device. The decomposition vessel has undergone
an EC prototype test. The CE declaration of con-
formity confirms that this decomposition vessel
corresponds to the pressure device described in
the EC prototype test certificate. The decomposi-
tion vessel has undergone a pressure test with
test pressure of 33 MPa and a leakage test with
oxygen at 3 MPa.
Refer also to the operating instructions for the
C 6010/ 6012 decomposition vessel, see chapter
„maintenance of the decomposition vessel“.
Decomposition vessels are experiment autoclaves
and must be tested by a technical expert after
each use.
Individual use is understood here to include a se-
ries of experiments performed under roughly the
same conditions in terms of pressure and tempe-
rature. Experiment autoclaves must be operated in
special chambers
The decomposition vessels must undergo repea-
ted tests (internal tests and pressure tests) perfor-
med 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 decompositionvessel.
The declaration of conformity becomes invalid if
mechanical modifications are carried out to the
experiment autoclaves or if tightness can no lon-
ger be guaranteed as a result of major corrosion
(e.g. pitting by halogens).
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.
The condition and function of the seals must be
checked and ensured by way of a leakage test
(see the operating instructions for the C 6010/
6012 decomposition vessel, section „Leaktight-
ness testing“).
If the maintenance, and especially the pressure
testing, is not performed or is performed incor-
rectly, 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.
Only technical experts may perform pressure
tests and service work on the decomposition vessel.

The IKA®C 6000 global standards/isoperibol cal-
orimeter system is used for calorific value determi-
nation of solid and liquid substances.
This is done by placing a known quantity of a
substance in a decomposition vessel which is sur-
rounded by a water jacket. The sample is then
combusted in an oxygen atmosphere . The calo-
rific 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.
The IKA®C 6000 global standards/isoperibol cal-
orimeter system is subject to the Pressure Vessel
Directive 2014/68/EU. Comply with the safety in-
structions accordingly.
For adaptation to individual laboratory tasks, use
original IKA®consumables and accessories.

System test
The system test is performed automatically every time the IKA®C 6000 global standards/isoperibol is
switched on.
During the system test the start screen is shown
again; clicking on the „Show details“ button pro-
vides detailed information.
Safety instructions regarding information on and
activation of the calorimeter are then shown on
the IKA®Homepage.
The system test includes the following steps:
- Testing the external water circuit with the cir-
culation pump and heater (approx. 30 to 45
seconds).
- Testing the internal water circuit with the con-
denser and water supply, plus the heater once
again (approx. 30 to 45 seconds).
- Testing whether the temperature of the cooling
waters is correct for the selected function of the
IKA®C 6000 global standards/isoperibol. (ap-
prox. 60 to 180 seconds).
If any one of these steps is not performed success-
fully, the system test stops with an error message.
After all the components have been checked the
system test can be restarted the same as after a
manual cancellation. To do this, press the „Re-
start“ button.
With the system test in standby, no measure-
ments can be made. However it is possible to se-
lect some menu options.
