3.24 Marking. Unless otherwise specified (see 3.1), each connector or adapter shall be marked in accordance with
MIL-STD-1285.
3.25 Solderability. Solder terminations shall withstand the test conditions specified in 4.6.20.
3.26 Resistance to soldering heat. Connectors shall withstand the test specified in 4.6.21.
3.27 Resistance to solvents. When tested as specified in 4.6.22, the connectors shall be visually inspected and shall
show no evidence of cracking, crazing, discoloration, distortion or bleeding of any foreign matter from the material.
Pitting shall not be allowed. The marking and color coding shall be legible.
3.28 Workmanship. Connectors shall be processed in such a manner as to be uniform in quality and shall be free
from defects that will affect life, serviceability, or appearance. There shall be no evidence of loose contacts, poor
molding or fabricating, damaged or improperly assembled contacts, peeling or chipping of the plating and finish, parting
lines of mold which would indicate improper molding techniques, improper tinning of terminals or eyelets and nicks and
burrs of metal parts surfaces.
3.29 Interchangeability. Printed wiring connectors of a given type, style, class, and size manufactured by one source
to the requirements of the specification shall be capable of mating with their associated printed wiring boards of
equivalent size manufactured to the requirements of the specification by other sources.
4. VERIFICATION
4.1 Classification of inspection. The inspections specified herein are classified as follows:
a. Qualification inspection (see 4.4).
b. Conformance inspection (see 4.5).
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 system to control the accuracy of the measuring
and test equipment (i.e. NCSL Z540-1, ISO 10012-1 part 1 or comparable standards) shall be required.
4.2.2 Assembly plants. Assembly plants shall 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 that established at the qualified
manufacturing plant. Quality control requirements, including Government inspection surveillance, shall be the same as
required for the qualified connector manufacturer.
