109 Retention of Blades Test

109.2 Receptacles having the break-off tab, when provided, removed from one nonidentified terminal are to be subjected to ten conditioning cycles of manual insertion and withdrawal of a standard gauge, see Figure 109.1. Each of six devices is to be tested. The gauge is to be configured as outlined in Table 109.1. The force applied to insert the gauge for any of the conditioning cycles is not to exceed 40 lbf (178 N). The gauge is to have the dimensions indicated in Figure 109.1 but is not to have holes in the outer ends of the blades.

109.3 The standard gauge is to be configured as shown in Table 109.2 using the line blades without holes and with the grounding blade removed. The gauge is then to be inserted in the receptacle and a static 3 lbf (13.3 N) (including the weight of the gauge), which tends to remove the gauge from the receptacle, is to be applied for a period of 1 minute in a direction normal to the plane of the face of the receptacle. There shall not be more than 0.079 inch (2 mm) displacement of the gauge.

109.4 The standard gauge is to be configured as shown in Table 109.3 using the line blades with holes in the end and with the grounding blade in place. The gauge is then to be inserted in the receptacle and a force applied in a direction normal to the plane of the face of the receptacle that tends to remove the gauge. The static force required to withdraw the gauge shall not exceed 15 lbf (67 N) (including the weight of the gauge).

109.5 Each of the line contacts of the receptacles is to be tested using the test blade illustrated in Figure 109.2. Each line contact shall be capable of withstanding for 1 minute a static 0.5 lbf (2.2 N) applied to the test blade in a direction normal to the plane of the face of the specimen and in a direction that tends to remove the test blade, when the test blade is fully inserted in the contact opening. There shall not be more than 0.079 inch (2 mm) displacement of the test blade.
