Valuation clause as stated in the contract.

4.4.4. Storage Case shall be secured using latches, and have carrying handles capable to support the weight of the Torque Calibration System and all components.

4.4.5. Storage Case shall be capable of fitting through a 6’X3’ Doorway.

4.4.6. Storage Case shall be no larger than 48 inch x 48 inch x 36 inch.

4.4.7. Storage case will be inspected by the Air Force and shall be free from any defects (i.e. poor molding fabrication, loose materials, damaged or improperly assembled cases, peeling, or chipping of plating or finish, nicks or burrs of metal parts, and post molding warping) which affect the durability, strength, safety, or serviceability. The finish of exposed edges/surfaces shall be smooth and free of sharp or jagged edges.

4.4.8. Storage case shall have cushioning and mounting provisions inside the case that provides protection to prevent damage from normal handling during transportation.

4.4.9. Storage case interior material shall be manufactured from a material that will not corrode any part of the Torque Calibration System; the material shall be oil resistant and not deteriorate.

4.5. Operating Environment/Storage: The Torque Calibration System shall be capable of operating to the specifications listed above in paragraph 2.0 in temperatures ranging from 60° F to 80° F with a Relative Humidity (RH) of 20% to 50%. The Torque Calibration System shall be capable of being stored in an environment of 0° F to 130° F, with a RH less than 95%.

4.6. Workmanship: The workmanship shall be first class, of neat general appearance in compliance with standard commercial practices. The standards of workmanship shall be such that the system complies with the requirements set forth in this purchase description.

5. OPERATOR’S MANUAL: The Torque Calibration System shall come with a Commercial Off The

Shelf (COTS) operator’s manual describing features and functions, assembly and start up, operation, instructions and troubleshooting, technical data, maintenance and care, and warranty.

6. TESTING: This item will be inspected and accepted at destination as stated in the contract. The item will be checked with test equipment with parameters equal to or better than those required to ensure that specified performance parameters are met. Test equipment used shall have first echelon certification directly traceable to the National Institute of Standards Technology (NIST) or other

AFMETCAL-approved equivalent international laboratory. Tests will be performed to ensure that the item meets the requirements of this purchase description. Such testing at destination does not relieve the contractor of performing all inspections and quality checks at the point of manufacture as necessary to assure performance as specified herein.
