8 inch printed wiring boards, and for interconnections between printed wiring boards. The connectors are intended to provide a reliable connection between printed wiring and conventional wiring. The interconnector concept is intended to provide connection of printed wiring on one board to printed wiring on another board.

b. Reference surfaces: The shock test shall be repeated in each of the referenced 90� axis positions.

c. Test condition letter: C.

d. Measurements and electrical loading: During test, all of the contacts shall be series wired and connected to a

suitable testing circuit with at least 0.1 ampere flowing through the contacts. During and after test, the

connectors shall be examined for evidence of mechanical failure of metallic or dielectric materials and for loss

of electrical continuity. Following this test, the contacts shall be subjected to the applicable contact

engagement and separation forces test specified in 4.6.6.

4.6.10 Bond strength, body assembly (see 3.14). The connector shall be subjected to the bond strength test to

determine the adhesive separation force. A test fixture such as specified on figure 5 shall be used to perform the tests.

Procedures shall be as follows:

a. Secure lower half of connector in a jig or fixture that is one-third the length of the connector, excluding the

mounting ears.

b. Support the connector by its normal mounting means only.

c. Gradually obtain a maximum applied force of 50 pounds, perpendicular to the mating surface of the parts.

4.6.11 Contact retention. The contacts shall be inserted into and extracted from each connector using the

applicable removal tool (see 3.1). After the tenth insertion, the connector shall be mounted to an appropriate fixture and

the straight axial load applied to the wire of the contacts (applicable to wire sizes 22 and larger). The contacts shall be

capable of withstanding the applied force.

4.6.12 Board insertion force (overstress) (see 3.16). Connectors shall be tested for high insertion force by inserting

the printed wiring test board specified on figure 2 for types A and AD connectors or mating the types CR and CS

assemblies and applying an axial force of 50 pounds in the direction of insertion. Connectors shall then be subjected to

the engagement and separation forces tests specified in 4.6.6 or 4.6.6.2, as applicable.
