Test overview

■ Purpose

Assuming vibration during transportation, to check for mass reduction, leakage, rupture, breakage, and ignition after the test.
With the exception of fully discharged batteries, the open circuit voltage is confirmed to be at least 90% of the voltage immediately before the test.
The customer using the test laboratory is assumed to use a safety device and to use a system that immediately stops the test in the event of a battery malfunction.

■ Test conditions

[ Vibration frequency range ] 7 Hz to 200 Hz
[ Acceleration level ] 7Hz to 18Hz 1gn constant / 18Hz to 50Hz double amplitude 1.6mm / 50Hz to 200Hz 8gn constant
[ Testing time ] 3 hours in each direction
[Vibration direction] 3 directions
In the latest version of UN38.3 issued in 2011, a condition for large batteries has been added to T3 and a maximum acceleration of 2gn has been added for 12 kg or more. (8gn for 12 kg or less).
