| No. | Item | Test Method | Criteria |
| 6.1 | Short- circuit Test | A cell is tested in accordance with 3.2, after that the cell is short-circuited by connecting the positive and negative terminals with a wire for 10min, the wire has a maximum resistance load of 5mΩ., then observe for 1h. | No fire, no explosion |
| 6.2 | Overcharge Test | A cell is tested in accordance with 3.2, then 1C constant current charged till the voltage reaches 1.5 times of the specified end-off charge voltage, or the charge time reaches 1h, then stop charge, and observe for 1h. | No fire, no explosion |
| 6.3 | Over discharge test | A cell is tested in accordance with 3.2, then 1C discharge for 90min, then observe for 1h. | No fire, no explosion, no leakage |
| 6.4 | Crush Test | A cell is tested in accordance with 3.2, and then is placed on the crush machine, the axis is parallel to the crush equiment, and it is crushed between two flat surfaces till the crushing force is gradually approaching 200 kN, or voltage reaches 0V,or reaches 30% distortion, then observe for 1h. | No fire, no explosion |
| 6.5 | Impact Test | A cell is tested in accordance with 3.2, and then placed on the impact flat. A Φ15.8mm bar is to be placed on the center of the cell. A 9.1kg weight is dropped from a height of 610mm onto the cell, the distortion is allowed. | No fire, no explosion |
| 6.6 | Stick Test | a) A cell is tested in accordance with 3.2 b) use φ5mm～φ8mm high temperature resistance steel needle, with speed of 25±5mm/s, to go through the cell from vertical direction of pole plate, the penetrate position should be close to the geometric center of plate surface, the steel needle remains in the cell; | No fire, no explosion |
