4.5.9 Cable retention (flat cable only) (see 3.5.7). The unmated wired connector with strain relief, when applicable,

shall be mounted by normal mounting means and aligned with the test fixture. An axial force of 8 ounces per contact

shall be applied. The force shall be applied 6 inches from the mating face of the connector to the cable and shall pull

away from the connector in a direction that will put the maximum stress on the contact-cable interface.

4.5.10 Insulation resistance at ambient temperature (see 3.5.8). Unmated connectors shall be tested in accordance

with test procedure EIA/ECA-364-21. The resistance shall be measured between the contact shell and a point

including 50 percent, (but not less than four) of the contact pairs adjacent to the contact shell, or between the contact

shell and a point including 50 percent, (but not less than six) of the contacts adjacent to the contact shell. The

contacts selected shall be those having the closest spacing between measurement points and the measured

resistance shall be

as specified in 3.5.8.

4.5.11 Contact resistance (nonremovable contacts)(see 3.5.9). Contacts shall be tested in accordance with test

procedure EIA-364-06. A minimum of four mated contacts or 20 percent of the mated contacts, whichever is greater,

shall be measured in each connector being tested. The following details apply:

a.

Wire size: As specified (see 3.1).

b.

Preparation: Connectors mated.

c.

Test current: Maximum contact current rating (see 3.5.9).

d.

Test circuits for nonremovable and classes H and K connectors shall be as shown in test procedure

EIA-364-06. Test circuit for IDC connectors shall be as shown on figure 3.

4.5.11.1 Classes H and K pin contacts. Classes H and K pin contacts shall be mated with counterpart copper

based alloy socket contacts for the test

specified in 4.5.11.

4.5.12 Contact engagement and separation forces (see 3.5.10). Contact engagement and separation forces shall

be tested in accordance with test procedure EIA-364-37. Four contacts or 20 percent of the contacts, whichever is

greater, shall be measured in each connector being tested. The following details apply:

a.

Insert and separate a maximum diameter pin in and from each socket contact, then insert and remove a

minimum diameter pin in the same sockets. During separation of the minimum diameter test pin, the

minimum separation force shall be

as specified in 3.5.10.

b.

Insert and separate a maximum diameter pin in and from each socket contact three times. During the third

cycle, the engagement force shall be

as specified in 3.5.10.
