34、 of the sleeve, about 15 cm in length, are subjected to humidity test of 13.4 and subsequently to the insulating resistance and electric strength tests according to clause 14. A suitable un-insulated copper conductor or metal rod is passed through the specimens, and the outside is covered by a metal
35、 foil in such a way that no flashover at the ends of the sample can occur. The measurement of the insulation resistance and the electrical strength test is made between the copper conductors/metal rod and metal foil. b) After the copper conductors/metal rod and metal foil have been removed, the spec
36、imens are placed in a cabinet for 240 h at the temperature of 140 C. c) The specimens are allowed to cool to room temperature and are then prepared as indicated under item a) above. 62080 Amend. 1 IEC:2008 5 Measurement of the insulating resistance and electric strength is then made between the copp
