IKA C 5010 Betriebsanleitung Seite 18

When handling combustion samples, combustion residues and auxiliary mate-
rials, the appropriate safety requirements must be observed. The following are
examples of substances that may cause dangers: corrosive, easily flammable,
capable of exploding, contaminated with bacteria, toxic.
Oxygen:
When working with oxygen, observe the appropriate requirements.
Danger warning: As a compressed gas, oxygen promotes combustion,
supports combustion intensively and may react violently with combustible
substances. Do not use any oil or grease!
Using a crucible made of stainless steel:
When using crucibles made of stainless steel, their condition should be
carefully checked after every experiment.
A reduction in the thickness of the material may cause the crucible to
burn and may damage the C 5010 and C5012 decomposition vessel.
For reasons of safety, crucibles must not be used any more after a maxi-
mum of 25 combustion procedures.
Specification of the decomposition vessel:
The decomposition vessel is manufactured in accordance with the regu-
lation for pressure vessels 97/ 23/ EC. This can be recognized from the
CE symbol with the identifying number of the testing station named.
The decomposition vessel is a pressure device of Category III. The de-
composition vessel has been subjected to an EC prototype test. The CE
declaration of conformity represents our guarantee to you that this de-
composition vessel complies with the pressure device described in the EC
prototype test certificate. The decomposition vessel has been subjected
to a pressure test at a test pressure of 330 bar (33MPa) and a leak
test with oxygen at 30 bar (3MPa).
C5010 and C5012 decomposition vessels are experi-
ment autoclaves and must be tested by a professio-
nally trained person each time before they are used.
An individual application is understood here to mean a
series of experiments that are performed under roughly
the same conditions in terms of pressure and temperature Experiment
autoclaves must be operated in special chambers (IKA
and C 2000).
Repeated tests:
The decomposition vessel must be subject to repeated tests (internal
tests and pressure tests) by a person with professional training. The
intervals between tests must be determined by the operator based on
experience, operating manner and the material used in the decompo-
sition vessel.
The declaration of conformity loses its validity if mechanical mo-
difications are made to the experiment autoclaves or if stability
can no longer be guaranteed as a result of heavy corrosion (for
example holes eaten in it by halogens).
The threading on the body of the decomposition vessel
and cap screw in particular are subject to a high level of
mechanical stress and must therefore be monitored regu-
larly for wear and tear.
The condition of the seals must be checked for functiona-
lity must be ensured by means of a test for leaks (see the chapter entitled
„Leakage test")
If maintenance tasks, and especially the pressure testing, is not perfor-
med or is performed incorrectly, there is a risk the pressure 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.
