QUALITY ASSURANCE PROVISIONS 4.1, Qualification Testing A. Sample Selection Samples shall be prepared in accordance with applicable Instruction Sheets and shall be selected at random from current production. All test groups shall consist of 3 connector pairs with each connector crimped to a 12 inch length of RG179A/U cabie for 75 ohm connectors and RG58/U, RGS8A/U, RGS8B/U or RG58C/U for 50 ohm connectors. Cable used for testing shall conform to MIL-C-17. B. Test Sequence Qualification inspection shall be verified by testing samples as specified in Figure 2. 4.2. Requalification Testing if changes significantly affecting form, fit or function are made to product or manufacturing process, product assurance shail coordinate requalification testing, consisting of all or part of original testing sequence as determined by development/product, quality and reliability engineering. 4.3. Acceptance Acceptance is based on verification that product meets requirements of Figure 1. Failures attributed to equipment, test setup or operator deficiencies shall not disqualify product. When product failure occurs, corrective action shall be taken and samples resubmitted for qualification. Testing to confirm corrective action is required before resubmittal. 4.4, Quality Conformance Inspection Applicable AMP quality inspection plan will specify sampling acceptable quality level to be used. Dimensional and functional requirements shall be in accordance with applicable product drawing and this specification. Note: (a) Vas is outer contact measurement. (b) Vee is inner contact measurement. (c) Measure 3 feet of cable and calculate milliohms per inch. Measure distance between probes on specimens and subtract equal distance of cable resistance to obtain actual contact resistance. (d) Establish base resistance measurements. Measure AR after test sequence. Figure 3 Termination Resistance Measurement Points Rev O 5415 Form 404-34 23Nov84
