4. VERIFICATION

4.1 Classification of inspections. The inspections specified herein are classified as follows:

a. Qualification inspection (see 4.3).

b. Conformance inspection(see 4.4).

4.2 Inspection conditions. Unless otherwise specified herein, all inspections shall be performed in accordance with

the test conditions specified in the "GENERAL REQUIREMENTS" of MIL-STD-202 and EIA-364.

4.2.1 Test equipment and inspection facilities. Test and measuring equipment and inspection facilities of sufficient

accuracy, quality and quantity to permit performance of the required inspection shall be established and maintained by

the contractor. The establishment and maintenance of a calibration program to control the accuracy of the measuring

and test equipment (i.e. NCSL Z540.3, ISO 10012 or comparable standards) shall be required.

4.2.2 Assembly plants. Assembly plants must be listed on or approved for listing on the applicable Qualified

Products List (QPL). The qualified connector manufacturer shall certify that the assembly plant is approved for the

distribution of the manufacturer's parts. The assembly plant shall use only piece parts supplied by the qualified

connector manufacturer. No testing other than visual inspection is required of certified piece parts obtained from the

qualified connector manufacturer, except when there is cause for rejection. All assemblies produced at the assembly

plant shall be subjected to inspection of product to assure that the assembly process conforms with established at the

qualified manufacturing plant. Quality control requirements, including Government inspection surveillance, shall be the

same as required for the qualified connector manufacturer.

4.2.3 Established reliability and high reliability practice. An established reliability and high reliability practice shall

be maintained in accordance with MIL-STD-790. Evidence of such compliance shall be verified by the qualifying

activity of this specification as a prerequisite for initial and continued qualification.

4.3 Qualification inspection. Qualification inspection shall be performed at a laboratory acceptable to the

alternate materials, platings, and processes shall be identified in the product test documentation (see 3.3.1).

4.3.1 Sample size.

4.3.1.1 Connectors. A minimum of 6 completely assembled plugs and receptacles of each class (1.3.1) of each

type (1.3.3), and of each style (1.3.2), with the largest insert arrangement for which qualification is desired shall be

subjected to the examinations and tests, except for thermal vacuum outgassing, in the sequence shown in table XI.

For classes D, K, and M, all the nonmetallic materials, including lubricants, of two additional connectors shall be

subjected to the thermal vacuum outgassing test. If classes G and N or M and D are being qualified at the same time,

a minimum of three completely assembled plugs and receptacles with the insert arrangement of the largest size

connector of the type (1.3.3) with the same style of termination (1.3.2), and each class (classes G and N, 3 class G, 3

class N; classes D and M, 3 class M, 3 class D) shall be subjected to the examinations and tests, except for thermal

vacuum outgassing, in the sequence shown in table XI. For classes D and M, all the nonmetallic materials, including

lubricants, of one additional connector of each class shall be subjected to the thermal vacuum outgassing test. The

connectors shall have a full complement of contacts. Half of the class H and class K contacts shall have solder cups

and the remainder shall have eyelets. The samples subjected to qualification testing shall be provided with

counterpart connectors for those tests requiring mating assemblies. The counterpart connectors provided for this

purpose shall be new, previously qualified connectors or new connectors submitted for qualification testing. Suppliers

not producing mating connectors shall submit substantiating, certification data that tests were performed with qualified

counterpart connectors. The samples shall be taken from a production run and shall be produced with equipment and

procedures normally used in production.

4.3.1.1.1 Printed wiring board connectors. When qualifying plugs and receptacles of printed wiring board

termination types, both the plug and receptacle shall be mounted to printed wiring boards and test as mated

connectors.
