4.4.3.1.4 Noncompliance. If a sample fails to pass group B inspection, the manufacturer shall notify the qualifying

activity and the cognizant inspection activity of such failure and take corrective action on the materials or processes, or

both, as warranted, and on all units of product which can be corrected and which were manufactured using essentially

the same materials and processes, and which are considered subject to the same failure. Acceptance and shipment

of the product shall be discontinued until corrective action, acceptable to the qualifying activity has been taken. After

the corrective action has been taken, group B inspection shall be repeated on additional sample units (all inspections,

or the inspection which the original sample failed, at the option of the qualifying activity). Group A inspection may be

reinstituted; however, final acceptance and shipment shall be withheld until the group B inspection has shown that the

corrective action was successful. In the event of failure after inspection, information concerning the failure shall be

made available to the cognizant inspection activity and the qualifying activity.

4.5 Methods of inspection.

4.5.1 Test methods. The following tests and test procedures assure connector integrity within typical operating

conditions and applications. Alternate commercial industry standard test methods are allowed. However when and

alternate methods are used, the qualifying activity must be notified prior to performance of the test. The test methods

described herein are proven methods and shall be the referee method in cases of dispute.

4.5.2 Visual and mechanical inspection. Connectors and contacts shall be examined to verify that the dimensions,

materials, design, construction, marking, and workmanship are in accordance with the applicable requirements (see

3.1, 3.3, 3.4, 3.6, and 3.7).

4.5.3 Magnetic permeability (classes M and N) (see 3.5.1). Permeability shall be measured on classes M and N

connectors with an instrument conforming to ASTM A342/A342M. The connectors may be wired or unwired, but shall

not be carrying current. Requirements shall be as specified in 3.5.1.

4.5.4 Maintenance aging (crimp contact connectors only (see 3.5.2)). Connectors shall be tested in accordance

with test procedure EIA-364-24. Installing/removal tools shall be in accordance with the applicable specification sheet

(see 3.1). Twenty percent of the contacts in a plug or receptacle, but not less than three contacts per connector

mating half, shall be tested.

4.5.5 Contact insertion and removal forces (see 3.5.3). Contacts shall be inserted and removed in accordance with

test procedure EIA-364-05. Installing/removal tools shall be in accordance with the applicable specification sheet

(see 3.1).

4.5.6 Mating and unmating force (see 3.5.4). Mated connectors shall be tested in accordance with test procedure

EIA/ECA-364-13. The rate of mating and unmating shall be 1 to 10 inches per minute.

4.5.7 Contact retention (see 3.5.5). Connectors shall be tested in accordance with test procedure EIA/ECA-364-29.

The following details shall apply:

a.

Axial direction: Shall be applied in both directions.

b.

Axial load: As specified.

4.5.8 Dielectric withstanding voltage (see 3.5.6).

4.5.8.1 Sea level. Unmated connectors shall be tested in accordance with test procedure EIA-364-20, condition I.

The applicable test voltages specified in 3.5.6 shall be applied between all adjacent contacts and between the shell

and each peripheral contact. Requirements shall be as specified in 3.5.6. For group A inspection testing, voltage may

be applied for a minimum of 10 seconds.

4.5.8.2 Altitude. The connectors shall be tested in accordance with test procedure EIA-364-20, condition IV. After

5 minutes at the simulated altitude, the connectors shall be tested as specified in 4.5.8.1.
