UN Test Data
1.Test Item: Altitude simulation (T1)
2.Test Purpose: This test simulates air transport under low-pressure conditions.
3.Test Procedure:
Test cells and batteries shall be stored at a pressure of 11.6kPa or less for at least six hours at ambient
temperature(20±5• Ž ).
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.
