QUALITY ASSURANCE PROVISIONS
Qualification Testing
A.
B.
Requalification Testing
If changes significantly affecting form, fit or function are made to the product or manufacturing process,
product assurance shall coordinate requalification testing, consisting of all or part of the original testing
sequence as determined by development/product, quality and reliability engineering.
Acceptance
Acceptance is based on verification that the product meets the requirements of Figure 1. Failures
attributed to equipment, test setup or operator deficiencies shall not disqualify the product. If product
failure occurs, corrective action shall be taken and specimens resubmitted for qualification. Testing to
confirm corrective action is required before resubmittal.
Quality Conformance Inspection
The applicable quality inspection plan shall specify the sampling acceptable quality level to be used.
Dimensional and functional requirements shall be in accordance with the applicable product drawing
and this specification.
Specimen Selection
Specimens shall be prepared in accordance with applicable Instruction Sheets and shall be
selected at random from current production. Test group 1 shall consist of 1 housing of each size
and 5 contacts all representative of the entire lot being tested. Test groups 2, 3 and 4 shall consist
of 6 connector assemblies per group. Housing and wire sizes shall be chosen randomly to cover
the range of the product line. Test group 5 shall consist of 15 contacts per wire size. Test group 6
shall consist of 15 contacts crimped on 18 AWG wire and tested with appropriate random
housings. All contacts shall be crimped to appropriate part number 103501 and 103502 tin plated
test conductors in accordance with Application Specification 114-1021. For tests which require
connector mating, .045 inch square or round posts shall be used.
Test Sequence
Qualification inspection shall be verified by testing specimens as specified in Figure 2.
