27.3 If the DUT is operational after the impacts it shall be subjected to a discharge and charging cycle in accordance with the manufacturer’s specifications. An observation period per 6.5 is then conducted.27.4 During the test, one of the detection methods outlined in Section 7 shall be used to detect the presence of combustible concentrations. If required based upon system design or installation, venting of toxic releases shall be continuously monitored during the testing per Section 11.27.5 After the observation period, the DUT shall be subjected to an ″as received″ dielectric voltage withstand test in accordance with Section 18. The DUT shall be examined for signs of rupture and evidence of leakage.27.6 As a result of the impact test, the following in (a) – (h) are considered non-compliant results. For additional information on non-complying results refer to Table 10.1.a) E – Explosion;b) F – Fire;c) C – Combustible vapor concentrations;d) V – Toxic vapor release;e) S – Electric shock hazard (dielectric breakdown);f) L – Leakage (external to enclosure of DUT);g) R – Rupture (of DUT enclosure exposing hazardous parts as determined by 5.3.3);h) P – Loss of protection controls
