IKA C 200 Operating Instructions Manual page 6

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!
Caution - magnetism! Beware of effects from the magnetic field (pacemakers, data media
etc.).
When using stainless steel crucibles thoroughly check their condition after each experi-
ment. If the material gets thinner, the crucible may catch fire and damage the decomposi-
tion vessel. Crucibles must not be used for more than 25 combustions for safety reasons.
The decomposition vessel is manufactured in accordance with the directive for pressure
equipment 97/23/EC. This is indicated by the CE symbol with the ID number of the noti-
fied body. The decomposition vessel is a category III pressure device. The decomposition
vessel has undergone an EC prototype test. The CE 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 330 bar and a leakage test with oxygen at 30 bar.
Decomposition vessels are experiment autoclaves and must be tested by a technical
expert after each 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 autocla-
ves must be operated in special chambers (C 2000, C 5000, C 7000, C 200).
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 determi-
ned by the operator on the basis of experience, type of operation and the material used
in the decomposition vessel
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).
The threads on the body of the decomposition vessel and the union nut are subject to
considerable stress in particular and must therefore be checked regularly for wear.
The condition and function of the seals must be checked and ensured by way of a leaka-
ge test (see operating instructions for decomposition vessel!).
Only technical experts may perform pressure tests and service work on the decomposi-
tion vessel
We recommend that you send the decomposition vessel to our factory for inspection,
and if necessary, repair after 1000 tests or after one year or sooner depending on use.
