idyNE ENGINl!l!IIING COllll'OIIATION TEST PROCEDURE AD296 Q2-1,-2 2.0 SCOPE 2.1 General - This document defines the test equipment and procedural steps which must be followed for complete acceptance testing of the AD296 Q2-1,-2 Digital PCBA. The card will be found acceptable if its performance is within the limits specified in this document.

2.1.1 Conditions - The following conditions will be established for the AD296 acceptance tests, unless noted otherwise herein.

2.1.2 Standard Conditions:

Temperat~re: Room ambient (68°F to 86°F)

Altitude/Pressure: Normal ground Humidity: 90% or less 2 .1.3 Power Requirements for Test Equipment:

115V AC+ 5%, single phase, 60 Hz+ 2%

• 2.2 FAILURES 2.2.1 Failure Definitions - Any test result which does not fall within the tolerances noted in this test procedure shall be construed to be a test failure.

Should a failure occur, the following action will be taken:

A. Prepare a failure report, noting the suspected cause of the failure, and submit the report in accordance with established procedures.

B. Determine the cause of failure. Document defects and repair.

C. Submit analysis to the procuring activity, if required.

D. Rerun the area(s) of this test procedure associated with the fail-ure to insure that the failure has been repaired.

2.2.2 Test Equipment Failures - A failure which occurs in any of the associated test equipments listed shall NOT be considered a test failure. Should a test equip-ment failure occur, the following action will be taken:

A. Determine the cause of failure B. Repair the failure

~. Continue the test procedure NUMBER REV ATP 447 A

AlidyNE ENOINEEIIINO CDIIIIOIIATIDN ACCEPTANCE TEST PROCEDURE AD296 Q2-1,-2 2.3 Human Induced Failures - Failures which occur due to human error in the operation of the test are considered human induced failures and shall not be considered test failures. Should a human induced failure occur, that portion of the test affected shall be rerun to satisfactorily demonstrate that the failure was due to operator error.

3.0 ACCEPTANCE TESTS 3.1 Visual acceptance Test - The Digital C~rd shall be visually inspected to

.

insure that it has been constructed in a professional manner

• 3.1.1 Workmanship - The equipment, including all parts and accessories, shall be determined to be constructed and finished in a thoroughly professional manner.

Particular attention shall be given to neatness and thoroughness of soldering, wiring, impregnation of coils, correct marking and installation of components and assemblies, welding and brazing, plating, painting, riveting, machining, machine screw assemblies, fitting, and freedom of parts from burrs and sharp edges.

3.1.2 Finish - Inspect the finish of the Card. Observe that the external sur-face is free of scratches or burrs. Observe that all threaded parts show no indi-cation of cross threading, detrimental or hazardous burrs, or mutilation between attached parts as possible.
