Extrusion test for nail penetration test machine: The battery under test was squeezed between two surfaces, Through pliers or pistons, About 13KN extrusion pressure is applied to the 32mm diameter hydraulic arm, The squeeze continues until the pressure gauge reading on the hydraulic device reaches 17.2Mpa, Once the maximum pressure is reached, the squeeze is lifted. For cylindrical batteries, squeeze the long shaft of the battery, It shall be parallel to the extrusion plane of the extrusion device.
For prismatic cells, The pressure shall be applied in one of two directions perpendicular to its long axis, And then squeeze in the other direction. For the button cell, extrude its plane. Each battery tested needs to be squeezed only once. Test standard for Wewon’s nail penetration test chamber comply with SJ/T 11169 (equal to UL 1642:2008), SJ/T 11170 (equal to UL 2054:2008), UL 1642, GB8897.4 2002 126.96.36.199, IEC 62133, IEC 60086-4:2000, QC/T 743-2006, QC/T 744-2006.
