14.3 Testing is repeated at a load

14.3 Testing is repeated at a load that draws a maximum current between 85% and 100% of the protector trip rating. For the purposes of this test, the protector trip rating for a fuse is defined as 2.0 x In where In is the fuse current rating per the Standard for Low Voltage Fuses – Part 1: General Requirements UL 248-1.14.4 Tests are to be conducted at room ambient. The samples are to reach thermal equilibriumtemperature as outlined in 6.3 before the terminals are connected.14.5 The sample is to be completely discharged (i.e. discharged until near zero state of charge/its energy is depleted), or protection in the circuit has operated and the temperature on the center module has peaked or reached a steady state condition and 7 h has elapsed, or a fire or explosion has occurred.14.6 During the test, samples supplied with protective devices shall be subjected to a single component fault using any single fault condition that may be determined to occur during discharge conditions. See Section 9 for details regarding single fault conditions. Single fault conditions can be applied to both passive and active protective devices. Exception: Components in circuits evaluated for reliability (i.e. evaluated for functional safety criteria considering single fault conditions in accordance with 5.8.1.3) need not be subjected to single fault conditions.14.7 During the test, a detection method as outlined in Section 7 shall be used to detect the presence of flammable concentrations if determined necessary. If required based upon system design or installation, venting of toxic releases shall be continuously monitored during the testing per Section 11.14.8 If the DUT is operational after the short circuit 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.14.9 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.
