Safety Instructions
General safety instructions
•
Read the operating instructions in full before starting up and
follow the safety instructions.
•
Keep the operating instructions in a place where it can be
accessed by everyone.
•
Ensure that only trained staff work with the instrument.
•
Follow the safety instructions, guidelines, occupational
health and safety and accident prevention regulations.
Intended purpose
•
The IKA C 62 pressure decomposition vessel is a calorimetric
decomposition vessel for determining the heat generated by
explosions in accordance with Technical delivery conditions
TL 1376-0600 Part 520. Work specification for chemical and
physical examination of propellants. 3.41 Determination of
heat generated by explosion by means of an isothermal/
isoperibolic/ static-jacket calorimeter; Bundesamt für Aus-
rüstung, Informationstechnik und Nutzung der Bundeswehr
(BAAINBw) Koblenz.
•
Operation of the C 62 decomposition vessel is only permitted
with the IKA C 2000 basic/ control calorimeter! The calor
meter must be equipped with the IKA C 60 Conversion Kit!
•
The decomposition vessel must only be ignited within the
standard modes with the C 2000 system setting "[ ] Explosi-
ve". Manual ignition is not permitted!
Conditions for operation
•
The maximum pressure in the decomposition vessel must not
exceed 1200 bar (1200 x 10
5
Pa).
•
The heat of explosion of the propellant is determined at a
loading density of 0.1 g/ml. With the available combustion
chamber volume of 25 ml, this corresponds to a maximum
amount weighed in of 2.5 g! Never fill the decomposition
vessel with a greater quantity! Check the condition of the
16
seals! Perform a leak test before every combustion (see page
26). Seal the decomposition vessel properly before every
measurement and make certain the discharge valve is seated
properly!
•
A damaged decomposition vessel must not be placed in ope-
ration! A decomposition vessel that is under pressure must
not be stored or transported!
•
Observe the accident prevention requirements appropriate
for the activity and the workstation! Wear your protective
personal equipment!
Notes on the sample
•
Materials whose combustion behaviour is unknown must be
tested for their chemical physical behaviour before the com-
bustion in the C 62 decomposition vessel!
•
Leave the room or maintain a distance from the calorimeter if
you are performing combustion on unknown samples!
Combustion residues and auxiliary materials
•
Toxic combustion residues in the form of gasses, ashes or
precipitates are possible on the inner walls of the decompo-
sition vessel. Observe the accident prevention requirements
applicable to the activity and workstation! Wear your perso-
nal protective equipment!
•
When working with combustion samples, combustion resi-
dues and auxiliary materials, the relevant safety requirements
must be observed. The following are examples of substances
that may pose dangers:
- corrosive
- readily ignitable
- capable of exploding
- contaminated with bacteria
- toxic
•
The decomposition vessel must only be opened under a la-
boratory exhaust hood that is running! Combustion residues
can cause corrosion! You must therefore thoroughly clean
and dry the decomposition vessel immediately after every
measurement!
Oxygen
•
You will require an oxygen connection with max. 40 bar to
check for leaks. When working with oxygen, observe the cor-
responding safety requirements.
•
Danger: when oxygen is a compressed gas, it pro-
motes combustion vigorously and may react violent-
ly with combustible materials. Do not use any oil or
grease.
Specification of the decomposition vessel
•
The decomposition vessel has been manufactured in ac-
cordance with the Regulation for pressure devices
2014/68/EU Modul A1. This is indicated by the identification
number of the location named. The decomposition vessel
has been subjected to an EC individual test. By way of the
CE declaration of conformity, we certify to you that this de-
composition vessel is in conformity with the pressure device
described in the EC individual test certification.
•
The decomposition vessel has been subjected to a pressure
test at a test pressure of 2500 bar. The permissible operating
pressure of 1200 bar may not be exceeded.
•
The maximum operating temperature may not exceed 50 °C.
•
The C 62 pressure decomposition vessel is a test autoclave
and must be tested every time after it is used by a know-
ledgeable professional. A single usage also includes a series
of tests that is performed at approximately the same stress
level in terms of temperature and pressure. Test autoclaves
must be operated in special chambers (for example the IKA
C 2000 basic/ control calorimeter).
Recurring tests
•
Decomposition vessels must be subjected to recurring tests
(internal test and pressure test) by a knowledgeable profes-
sional. The timing of these tests will be determined by the
operator based on experience, the manner of operation and
the coating material.
•
The declaration of conformity loses its validity if mechanical
changes are made to the test autoclave or if its stability can
no longer be guaranteed due to very heavy corrosion (for
example holes caused by halogens). Especially the threading
on the body of the decomposition vessel and the nut as well
as the discharge valve are subject to a high level of stress,
and must therefore be checked regularly for wear and tear.
•
The status of the seals must be checked and their functional-
ity ensured by means of a leak test (see: Checking for leaks /
evacuate/ rinsing).
•
Pressure tests and service tasks on the decomposition ves-
sel must only be performed by knowledgeable professionals.
•
We recommend that you send the decomposition ves-
sel in to our factory to be checked and repaired if nec-
essary after 1000 test or after one year or, depending
on the application for which it is used, even sooner.
Definition of a knowledgeable professional
A knowledgeable professional as the term is used in these opera-
ting instructions is only someone who:
1.
is able to ensure as a result of his or her training, knowledge
and experience gained through practical activities that the
tests will be properly performed.
2.
has the necessary dependability.
3.
is not subject to any instructions in terms of the test activity.
4.
if necessary, has suitable testing equipment available.
5.
can provide suitable proof of the requirements listed in 1.
