UN Test Data
1.Test Item: Shock (T4)
2.Test Purpose: This test simulates possible impacts during transport.
3.Test Procedure:
Test cells and batteries shall be secured to the testing machine by means of a rigid mount which will support all mounting
surfaces of each test battery. Each cell or battery shall be subjected to a half-sine shock of pack acceleration of 150 g
and pulse duration of 6 milliseconds. Each cell or battery shall be subjected to three shocks in the positive direction
followed by three shocks in the negative direction of three mutually perpendicular mounting positions of the cell or
battery for a total of 18 shocks.
However, large cells and large batteries shall be subjected to a half-sine shock of peak acceleration of 50 g
duration of 11 milliseconds. Each cell or battery is subjected to three shocks in the positive direction followed by three
shocks in the negative direction of each of three mutually perpendicular mounting positions of the cell for a total of 18
shocks.
SANYO Internal Procedure:
As above.
4.Test Requirements:
No mass loss(less than 0.1%),no leakage,no venting,no disassembly,no rupture and no fire,and the voltage
retention is not less than 90%.
The requirement relating to voltage is not applicable to test batteries at fully discharged states.
