9.2Tensile test
9.2.1The conductor shall be inserted through a punched hole in a plate which is securely fastened to atensile machine. A minimum force in accordance with Table 8 shall be applied at a rate not to exceed 25.4mm per min (1 in per min).The force shall be applied for 1 min.
9.3 Mold stress test
9.3.1 Fully assembled ferrules shall be placed in a full-draft circulating-air oven for 7 h.The temperatureshall be maintained at a uniform temperature of not less than 90 °C (194 °F).
9.3.2The assembled ferrules shall be removed from the oven and allowed to cool to room temperaturebefore determining compliance.
9.3.3 The connector shall be subjected to and comply with the dielectric voltage withstand test in 9.4.
9.4Dielectric voltage withstand test
9.4.1 After completing the mold stress test, assembled samples shall be subjected to an ac test potentialof 1000 v for a period of 1 min.Each sample shall be embedded in No.7-1/2 conductive shot that is toserve as the outer electrode (see Figure 11).Only that portion of the plastic sleeve that covers uninsulatedcurrent-carrying parts shall be covered with the outer electrode.A smaller than No.7-1/2(higher sizenumber) shot may be used with the concurrence of those concerned.Conductive metal foil shall be usedas the outer electrode when the ferrule has openings that will allow entry of the shot.
