Table 1 – Classification of tests
No. 5 Surge discharge test
Replace: Surge discharge test by: Short-circuit test

5.7 Surge discharge test (under consideration)
Replace subclause 5.7 by the following:
5.7 Short-circuit test
5.7.1 General
Unless otherwise specified, the short-circuit test for the capacitor cell shall be carried out by
the following procedure.
5.7.2 Preconditioning
The capacitor shall be treated according to 5.1.4 and 5.1.5.
5.7.3 Initial measurement
The capacitance and internal resistance of the capacitor shall be measured in accordance
with 5.3.
5.7.4 Test method
The capacitor shall be charged by means of a d.c. source up to U within 5 min and be held
R
for 5 min then short-circuited through appropriate discharge circuit. The test shall be repeated
5 times. The test should be repeated after the capacitor temperature reaches thermal
equilibrium with surrounding temperature.
The resistance of the discharge circuit (cables, switches, shunts or electronic) shall be equal
to or less than the internal resistance of the capacitor or 1 mΩ, whichever is lower. Capacitor
cells can be connected in series for this test.
5.7.5 Post treatment
The capacitor shall be treated according to 5.1.5 and discharged through the suitable
discharge device.
5.7.6 Final measurement
The capacitance and internal resistance of the capacitor shall be measured in accordance
with 5.3.
5.7.7 Acceptance criteria
The capacitance change and internal resistance change shall be within the values as agreed
between the manufacturer and the purchaser.
No visible damage and no electrolyte leakage shall be observed.

5.11 Endurance cycling test
Replace subclause 5.11 by the following:
5.11 Endurance cycling test
5.11.1 General
Unless otherwise specified, the endurance cycling test for the capacitor shall be carried out
by the following procedure. For capacitor module or bank, this test may be substituted by
capacitor cell test, when agreed between the manufacturer and the purchaser.
NOTE The purpose of the endurance cycling test is to demonstrate the performance of the capacitor under the
conditions which will actually occur in service.
5.11.2 Preconditioning
The capacitor shall be treated according to 5.1.4 and 5.1.5.
5.11.3 Initial measurements
The capacitance and internal resistance of the capacitor shall be measured in accordance
with 5.3.
5.11.4 Test method
5.11.4.1 Test temperature
Test temperature shall be 10 °C lower than the maximum operating temperature specified by
the manufacturer.
Test temperature shall be measured at the capacitor cell case for capacitor cell and at the
hottest cell in the module or bank for capacitor module or bank.
5.11.4.2 Apparatus
The charge and discharge device shall be capable of charging and discharging the capacitor
with the constant current as specified in 5.11.4.3.
At the charge and discharge cycles, monitoring the voltage-time curves of the all capacitor
cells within the test set-up should be carried out.
5.11.4.3 Test steps
Unless otherwise specified, the test shall consist of the following steps, repeating c) through f)
continuously (see Figure 3) until the end of test criteria is reached:
a) charge up to U with constant current of 5 mA/F per cell;
R
b) continue charging at U for 30 min;
R
c) discharge down to 0,5U with constant current of 50 mA/F per cell;
R
d) pause for 15 s without charging current;
e) charge up to U with constant current of 50 mA/F per cell;
R
f) hold for 15 s at constant voltage U
R.
