C 1: The pressure vessel is integrated
DANGER
into the calorimeter C 1. The maxi-
mum extra energy added to the pres-
sure vessel must not exceed 40,000 J (select the test
mass accordingly). The permitted operating pressure of
142 bar (14.2 MPa) must not be exceeded. The maxi-
mum permitted operating temperature must not exceed
50 °C.
WARNING
When burning substances containing
metals, ensure that the maximum en-
ergy input is not exceeded!
WARNING
Only fill the decomposition vessel (C 6010
/C 6012) or calorimeter system (C 1)
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.
WARNING
Some materials tend to explode when
combusted (e.g. due to formation of
peroxides), which could cause the decomposition vessel
to crack. The calorimeter can not be used for test-
ing explosive samples.
WARNING
If the burning behavior of a material is
unknown, it must be tested before com-
bustion in the decomposition vessel (risk of explosion). If you
are burning unknown samples, leave the room or keep
enough distance from the calorimeter.
WARNING
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 vapor pressure (e.g. tetramethyl dihydrogen
disiloxane) must not directly touch the cotton thread! Fur-
thermore, toxic combustion residue in the form of gases,
ashes or condensation, for example, is possible in the in-
ner wall of the decomposition vessel.
DANGER
Observe the accident prevention re-
quirements 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
WARNING
Please observe the relevant regulations
when handling oxygen. Oxygen as a
compressed gas is oxidising; intensively aids combustion; can
react violently with flammable materials.
DANGER
Do not use oil or grease!
• Tubes and screwed joints for oxygen must be kept free of
grease.
WARNING
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 de-
pressurized.
WARNING
When using stainless steel cruci-
bles, 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 com-
bustions for safety reasons.
NOTICE
C 6000 global standards/isoperi-
bol: The decomposition vessel is man-
ufactured in accordance with the directive for pressure
equipment 97/23/EC. This is indicated by the CE symbol
with the ID number of the notified body. The decomposi-
tion vessel is a category III pressure device. The decompo-
sition vessel has undergone an EC prototype test. The EC
declaration of conformity confirms that this decomposi-
tion vessel corresponds to the pressure device described
in the EC prototype test certificate. The decomposition
vessel has undergone a pressure test with test pressure
of 330 bar (33 MPa) and a leakage test with oxygen at
30 bar (3 MPa).
NOTICE
C 1: The EC Declaration of Conformity
confirms that this pressure vessel was
manufactured by the Pressure Equipment Directive 97/23/
EC. (Article 3, paragraph 3). The pressure vessel has under-
gone a pressure test with test pressure of 203 bar (20.3
MPa) and a leakage test with oxygen at 40 bar (4 MPa).
C 6000 global standards/isoperibol:
The CE declaration of conformity confirms that this de-
composition vessel corresponds to the pressure device
described in the EC prototype test certificate. The decom-
position vessel has undergone a pressure test with test
pressure of 33 MPa and a leakage test with oxygen at
3 MPa.
