Test procedure:
Cells and batteries are firmly secured to the platform
of the vibration machine without distorting the cells in
such a manner as to faithfully transmit the vibration.
The vibration shall be a sinusoidal waveform with a
logarithmic sweep between 7 Hz and 200 Hz and
back to 7 Hz traversed in 15 minutes. This cycle
shall be repeated 12 times for a total of 3 hours for
each of three mutually perpendicular mounting
position of the cell. One of the directions of vibration
must be perpendicular to the terminal face. The
logarithmic frequency sweep is as follows: from 7 Hz
a peak acceleration of 1 g
n
is maintained until 18 Hz
is reached. The amplitude is then maintained at 0,8
mm (1,6 mm total excursion) and the frequency
increased until a peak acceleration of 8 g
n
occurs
(approximately 50Hz). A peak acceleration of 8 g
n
is
then maintained until the frequency is increased to
200 Hz

Requirement:
Cells and batteries Mass loss limit: ≤0,1%
.
P
Open circuit voltage changed not less than 90%, the
requirement relating to voltage is not applicable to
test cells and batteries at full discharged states.
P
No leakage, no venting, no disassembly, no rupture
and no fire.

Test T.4: Shock
P
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 peak acceleration of 150 gn 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 or peak acceleration of 50 gn and pulse
duration of 11 milliseconds. Each cell or battery is
subjected to three shocks in the positive direction
followed by three shocks in the positive direction
followed by the negative direction of each of three
mutually perpendicular mounting positions of the cell
for a total of 18 shocks.
