15.2 The DUT is to be subjected to

15.2 The DUT is to be subjected to a constant discharging current/power that will discharge a battery at the manufacturer’s specified maximum discharge rate. The test will continue until the passive protection device(s) are activated, or the minimum cell voltage/maximum temperature protection is activated, or the DUT has been discharged for an additional 30 min after it has reached its specified normal discharge limit, whichever comes first.15.3 During the test, a detection method as outlined in Section 7 shall be used to detect the presence of flammable concentrations as determined necessary. If required based upon system design or installation, venting of toxic releases shall be continuously monitored during the testing per Section 11.15.4 If the DUT is operational after the overdischarge protection test it shall be subjected to a charge and discharge cycle in accordance with the manufacturer’s specifications. See 10.2 for details regarding user resettable devices. An observation period per 6.5 is then conducted.15.5 At the conclusion of the observation period, the samples shall be subjected to the ″as received″ dielectric voltage withstand test in accordance with Section 18. The DUT shall be examined for signs of rupture and evidence of leakage.
