1. Check test instruments and ensure specimens are in place.
2. Put the cell between 2 flat surfaces in the test chamber. ( Prismatic or pouch cells shall be crushed by exerting the force to this widest side. Button/coin cells shall be crushed by exerting force on its flat surfaces. For cylindrical cells, the crushing force shall be applied perpendicular to the longitudinal axis. Each test cell only allows being subjected to one crush. The specimen should be observed for 6 hours after the test. The test shall be carried out using test samples that have not previously been subjected to other experiments).
3. Start the machine to empower the flat surfaces to exert gradual force with a speed of approx. 1.5 cm / s at the first point of contact. The crush is to be continued until the first of below three conditions below is attained:
A) Crushing force up to (13±0.78) kN.
B) The voltage of cell drops by at least 1/3 or 100mV(based on UN38.3 test standard).
C) The cell is deformed by 1/10 or 50%(based on UN38.3 test standard) of its original thickness.
4. The pressure should be released once it satisfies any one of the above 3 options. Cells meet the requirements if their external temperature does not exceed 170℃ and no disassembly, and no fire during the test and within 6 hours after the test.
The above is just for reference. Please strictly follow the procedure of the applied standard to carry out the test when you get this testing machine.
