IKA C 6000 isoperibol Package 2/12 - Manual (Page 6)

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
A pressure test must be performed after a
decomposition vessel has reached or exceeded the
recommended number of ignition cycles. 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
the sections “Maintenance of the Decomposition
Vessel” 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
instructions in this respect. The user will be given
specifi c 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 suffi 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
requirements listed in 1.
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 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 accordance with the directive for pressure
equipment 97/23/EC. This is indicated by the CE
symbol with the ID number of the notifi ed body.
The decomposition vessel is a category III pressure
device. The decomposition vessel has undergone
an EC prototype test. The CE declaration of
conformity confi rms that this decomposition
vessel corresponds to the pressure device
described in the EC prototype test certifi cate. The
decomposition 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
series of experiments 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 (internal 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 decompositionvessel.
The declaration of conformity becomes invalid if
mechanical modifi cations 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).
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 „Leaktightness
testing“).
If the maintenance, and especially the pressure
testing, is not performed or is performed
incorrectly, there is a risk the decomposition vessel
may burst or an uncontrolled internal fi re 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.
