The sample is heated in a natural convection or forced convection oven. The oven temperature is heated to 130 ° C ± 2 ° C at the speed of 5 ± 2 * C / min, and then it will be constant, and it will stop after being maintained for 10min.
Result: no fire, no explosion.

The test chamber shall be heated at the temperature rise rate of (5 ± 2) ° C / min. when the temperature in the chamber reaches 130 ° C ± 2 ° C, it shall be kept constant for 30min.
Result: no fire, no explosion.

The fully charged battery shall be placed in a natural convection or circulating air convection oven for 1H when the ambient temperature is 20 ° C ± 5 ° C. the oven temperature shall be increased at the rate of 5 ° C / min ± 2 ° C / min to 130 ° C ± 2 ° C for 30min.
Result: no fire, no explosion.
