In order to be able to use the appliance properly and safely, every user must first
read the operating instructions and observe the safety instructions contained
therein. Take care of these operating instructions and keep them in a place where
they can be accessed by everyone.
The C 5000 calorimeter system may only be used to determine the gross calorific
value of solid and liquid materials in accordance with DIN 51900, BS 1016 T5, ISO
1928, ASTM 5468, ASTM 5865 and ASTM 4809. For this purpose, use only original
IKA  decomposition vessels C 5010 and C 5012. For further details please see the
operating instructions of the decomposition vessels C 5010 and C 5012.
The maximum amount of energy input into the decomposition vessel must not ex-
ceed  - (select the weight of the sample accordingly). The permissible oper-
ating pressure of  EDU  0SD must not be exceeded. The maximum permissi-
ble operating temperature must not exceed  ƒ& .
Do not fill the decomposition vessel too full of the sample. Only fill the decomposi-
tion vessel with oxygen up to a maximum pressure of  EDU  0SD . Monitor the
adjusted pressure on the pressure reducer of your oxygen supply. Perform a leak-
age test before every combustion (please observe the operating instructions of the
decomposition vessels C 5010 and C 5012, chapter ”Leakage test”).
Many substances tend to combust in an explosive manner (for example because of
the formation of peroxide). This may cause the decomposition vessel to burst.

Substances of which the combustion behavior is not known must be examined for
their combustion behavior before combustion in the decomposition vessel C 5010 or
C 5012 (danger of explosion). If you are burning XQNQRZQ VDPSOHV , leave the room
or NHHS D VDIH GLVWDQFH between you and the calorimeter.
Benzoic acid must only be burned in the form of pellets! Combustible dust and pow-
der must be compressed into pellets before combustion. Oven-dry dust and powder
such as wood chips, hay, straw, etc. burn in an explosive manner! They must be
moistened first! Readily combustible liquids with a low vapor pressure must not be
come in direct contact with the cotton thread (for example tetramethyl dihydrogen
disiloxan)!
In addition, toxic residues of combustion are possible in the form of gases, ash or
precipitates on the inner wall of the decomposition vessel, for example.

When handling combustion samples, combustion residues and auxiliary materials,
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
