Specimens shall be prepared in accordance with applicable Instruction Sheets and shall be
selected at random from current production. Test groups 1 and 2 shall each consist of: 6, 28
position assemblies; 60 terminals crimped to 22 AWG wire; and 60 terminals crimped to 26 AWG
wire. Test groups 3 and 4 shall each consist of: 5, 28 position assemblies and 100 terminals
crimped to 22 AWG wire. Test group 5 shall consist of: 5, 28 position assemblies; 5, 3 position
assemblies; 5, 10 position assemblies; 5, 18 position assemblies; and 295 terminals crimped to 22
AWG wire. Test group 6 shall consist of 25 specimens of each wire size.
B. Test Sequence
Qualification inspection shall be verified by testing specimens as specified in Figure 2.

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.
4.3. 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.
