Safety Instructions - IKA C 200 Operating Instructions Manual

For your protection
• Read the operating instructions in full
before starting up and follow the safety
instructions.
• Keep the operating instructions in a place whe-
re they can be accessed by everyone.
• Ensure that only trained staff work with the ap-
pliance.
• Follow the safety instructions, guidelines,
occupational health and safety and acci-
dent prevention regulations.
• Wear your personal protective equipment
in accordance with the hazard category
of the medium to be processed.
• Calorimeter system C 200 may only be used to
determine the calorific value of solid and fluid
materials. Only the appropriate original IKA
decomposition vessels may be used for this
purpose. For detailed information, please see
the operating instructions for the decompositi-
on vessels.
• The maximum extra energy added to the de-
composition vessel must not exceed 40,000 J
(select the test mass accordingly). The permit-
ted operating pressure of 230 bar must not be
exceeded. The maximum permitted operating
temperature must not exceed 50 °C.
• Do not overfill the decomposition vessel with
sample. Only fill the decomposition vessel with
oxygen to a maximum pressure of 40 bar.
Check the set pressure on the pressure reducer.
Perform a leakage test before each combustion
process (follow operating instructions for de-
composition vessel!).
• Some materials tend to explode when combus-
ted (e.g. due to formation of peroxide), which
could cause the decomposition vessel to crack.
• Standard decomposition vessels may not
be used for testing explosive samples.
• If the burning behaviour of a material is unk-
nown, it must be tested before combustion in
the decomposition vessel (risk of explosion). If
you are burning unknown samples, leave the
room or keep your distance from the calorime-
ter.
• Benzoic acid may only be combusted in its
pressed form! Flammable dust and powder
must be first pressed. Oven-dry dust and pow

roughly check their condition after each expe-
riment. 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.
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 decompositi-
on vessel is a category III pressure device. The
decomposition vessel has undergone an EC
prototype test. The CE declaration of confor-
mity confirms that this decomposition vessel
corresponds to the pressure device described in
the EC prototype test certificate. The decompo-
sition vessel has undergone a pressure test
