8 General
8.1 A connector arid a production tab shall be In compliance with the requirements of the Crimp Pull-Out Test. Section 10.
8.2 A connector shall be In compliance with the requirements of the Engagement-Disengagement Test, Section 11 and the Temperature and Heat Cycling Tests. Section 12,
Exception: The Disengagement portion of The Engagement-Disengagement Test need not be performed on connectors that have a locking feature,
8.3 Compliance of a connector shall be based on the use ot test tabs. A double-ended test tab shall be used for temperature and heat cycling tests. A single-ended test tab shall be used for all mechanical tests in this standard.
8.4 Insulated terminals shall additionally be in compliance with the requirements of the Dielectflc Strength Tests, Section 13, and Secureness of Insulation Test, Section 14.
8.5 The insulation of a terminal shall not crack or break when the terminal is assembled as intended on an insulated wire or wires.
8,6 A terminal that is intended for both field terminations of conductors and internal wiring Connections shall be tested using the wires specified in 9.3 and 9.4.
9 Preparation of Samples
9.1 To determine if a terminal complies with the requirements in 8.1, representative samples of the terminal shall be assembled to lengths of wire or wires of the size or sizes and In the manner specified by the manufacturer, see 16.7.
9.2 For the Crimp Pull-Out Test, SectIon 10, and the Engagement-Disengagement Test, Section 11 • ten new connectors and ten new single-ended test tabs shall be used for each test. For the Temperature and Heat Cycling Tests, Section 12, ten new connectors and five new double-ended test tabs shall be used.
Additional connectors and tabs are necessary to complete the test circuit Illustrated in Figure 12.1.
92 revised March 8. 2005
9.3 TIn-plated wire with stranding, as specified in Table 9.1 under the heading nternaI wlring shall be used for tests on a terminal intended only for internal wiring connections. The wire shall have thermoplastic insulation not greater than 1/32 inch (0.8 mm) thick.
12.1.4 The tests described in 12.21 and 12.3.1 — 12.3.2 shall be conducted in a location where the air flow does not exceed 25 fvmin (0.12 mIs) and under the conditions described in 12.1.5 — 12.1.7.
12.1.5 The test shall be conducted at an ambient temperature of 25 ±5C (77 ±9F). The temperature rises specified in 12.2.1 and 12.3.1 shall be the observed temperatures of the connector mnus the observed ambient temperature.
12.1.6 Any 60 Hz voltage that will result in an essenbally sinusoidal current of the specified value flowing through the connector meets the intent of this requirement.
12.1.7 The temperature shall be measured with thermocouples consisting of 30 AWG Iron and constantan wires The thermocouples and related instwrnent5 shall be calibrated to take consistently accurate measurements. Each thermocouple shall make contact with the surface being tested and shall not be relocated during the tests. A temperature shall be stable when three successive readings taken at intervals of 5 minutes indicate no further rise above the ambient temperature. A terminal does not meet the intent of this requirement when any one of the measured connector temperatures show a rise of more than those specified in 12.2 and 12.3.
12.2 Temperature test
12.2.1 The temperature rise of a connector shall not exceed 30C (54F) when the connector is continuously conducting the current specified in Table 12.1 or Table 12.2. as applicable.
