INSPECTION TEST REPORT REQUIREMENTS

CELL FIXTURES

Inspection test reports for each of the cell fixtures shall be provided along with proof that measuring equipment utilized is traceable to ANSI/ISO/NIST standards. The inspections test results shall insure that manufactured fixtures are IAW dimensions and tolerances as specified on AF drawings X201237075-

“Tombstone Tooling Block 32”x32”x55”-HMC1250”, X20123707-“Tombstone

Tooling block 32”x32”x35”-HMC1250” and X201237077-“T-Frame Fixture

10”x65”-HMC1250”.

The inspection test report for each tooling block and T-frame fixture shall include measured values for below listed features:

-Overall height, Base LxWxH, column face W x H, -True position of ½” dowel pin holes

- Bore size tolerance, -Adjacent hole spacing tolerance, -Parallelism of opposing faces, -Perpendicularity of faces to base datum, -Hole to any hole grid tolerance, -Locating center hole bore size tolerance/counterbore and depths, -Center locating plug diametric size, tolerance and length, -Flatness and surface finish and

-Position of mounting holes.

Inspection test reports for the tombstone tooling blocks and T-frame fixtures shall be furnished to the contracting officer at least 20 days prior to shipment for approval. Fixtures shall not be shipped to Tinker AFB without written approval of the inspection test reports.
