2 Safety
2.1 Intended use
The test chamber is designed for leak testing of Li-ion cells and Li-ion batteries.
Uncharged cells/batteries can be tested safely. For testing charged cells/batteries,
further safety measures must be taken to avoid personal injury and damage to
property.
• For validation of the test, cells prepared as leaky are placed in the chamber. The
preparation of the cells, which creates further hazards, is performed by the
operator and is not an integral part of the test or the device. Testing of leaking
cells will result in soiling of the test chamber and possibly "contamination". Cells to
be tested with the test chamber must be pre-qualified. For this purpose,
uncharged cells are examined, for example, to determine whether they can
withstand the stresses of the leak testing. Suitable measures for the safety of man
and machine must be taken by the operator.
• The test objects must be filled with an electrolyte in which one solvent component
ideally consists of dimethyl carbonate (DMC, CAS No. 616-38-6).
• Depending on the internal structure of the test objects and the external
geometries, local mechanical stresses can occur on the test objects. This can
damage the test objects themselves, but also other components located in the test
chamber.
• Make sure that the test chamber and the outer wall of the test objects are clean.
Leak testing with charged test objects represents an additional safety risk and
should only be carried out by appropriately trained personnel and with the
installation of further safety measures.
• To avoid short circuits between the test object and chamber wall, use the insulator
included in the scope of delivery.
• An external pump may optionally be connected to the ISO-KF16 connection
according to the specifications in the documentation. The pump is not included in
the scope of delivery. The pump capacity must be at least 40 L/min up to 1000 L/
min. The optional external pump must be connected via an electrically switchable
valve, a corrugated hose and, if required, a suitable adapter.
Incorrect usage Avoid the following unintended uses:
• Testing of partially or fully charged cells and batteries without further safety
measures.
• Use outside the technical specifications, see "Technical Data".
• Testing of non-vacuum Li-ion cells, batteries or other test objects.
