No.	Items	Test Method and Condition	Criteria
1	Thermal exposure test	Each fully charged cell, stabilized at room temperature, is placed in a circulating air-convection oven. The oven temperature is raised at a rate of 5 °C/min ± 2 °C/min to a temperature of 130 °C ± 2 °C. The cell remains at this temperature for 10 min before the test is discontinued.	No fire, No explosion
2	Low pressure	Each fully charged cell is placed in a vacuum chamber, in an ambient temperature of 20~25℃. Once the chamber has been sealed, its internal pressure is gradually reduced to a pressure equal to or less than 11.6 kPa (this simulates an altitude of 15240 m) held at that value for 6 h.	No leakage, No fire, No explosion
3.	Short test	The fully charged battery is to be short-circuited by connecting the positive and negative terminals of the battery with resistance load not exceed 100mΩ. Tests are to be conducted at room temperature 20~25℃.	No fire, No explosion The Temperature of the Battery surface not exceeded than 150℃
4	Forced discharge test	A discharged cell is subjected to a reverse charge at 1C for 90 min.	No fire, No explosion
5	Over charge test	After standard charge, continue to charge with a constant voltage 4.6V per a cell, holding 8h.	No leakage, No fire, No explosion
6	Soak Test	Put the batteries into clean water, be soaked for 24 hours.	No break, No fire
