TEST PROCESS
The test should be carried out at an ambient temperature of 20℃±5℃. The battery connected to the thermocouple (the contact of the thermocouple is fixed on the large surface of the battery) is placed in a fume hood, and the non-corrosive rust steel with a diameter of 2-8mm is used.
The needle pierces the center of the largest surface of the battery at a speed of (25±5) mm/s perpendicular to the direction of the battery plate, and keeps it for 10 minutes. The cone angle of the needle tip is 45°~60°. The surface of the needle is smooth and free of rust. Oxide layer and oil pollution, the tested battery does not explode, and it does not ignite as qualified.
1). For cylindrical batteries, the longitudinal axis of the acupuncture battery should be parallel to the two plates of the acupuncture device.
2). For square and soft-pack batteries, puncture only the center section of the wide surface of the battery.
3). For coin-type or button-type batteries, the upper and lower planes of the battery are parallel to the plate for puncture.
