125.	Materials are not corrosion resistant or treated to be made corrosion resistant for
126.	the applicable storage and operating environment. Dissimilar metals as defined in MIL-STD-889 are	3.3.1
127.	not effectively insulated from each other. Contractor does not have documentation	3.3.1
	available for identification of material, material finishes or treatments.	3.3.1

4.4.2 Operational run-in. Each item of equipment shall be serviced as required and shall be run-in in accordance with the manufacturer's normal procedures for a period of not less than

60 minutes. One or more functional defects shall constitute failure and acceptance of the equipment shall not be approved until all defects are corrected.

4.5 Inspection comparison. When initial production inspection is specified the Government may select rollers at any time during the contract production period and subject these rollers to the examination specified in 4.4.1 and the tests specified in 4.3.3 to determine conformance to

the requirements of this specification. The inspection will be performed by the Government, at a site selected by the Government, on units selected at random from those which have been accepted by the Government and will not include the previously inspected preproduction roller and initial production roller. In addition to any test specified as part of the inspection comparison, the Government reserves the right to conduct any and all other tests contained in

this specification as part of the inspection comparison and failure of such additional tests shall

have the same effect as failure of those tests specified as inspection comparison.

4.5.1 Inspection failure. Failure of an inspection comparison roller to meet any requirement specified herein during and as a result of the examination and tests specified in 4.3.3 shall be cause for refusal by the Government to continue acceptance of production rollers until evidence has been provided by the contractor that corrective action has been taken to eliminate the deficiencies. Correction of such deficiencies shall be accomplished by the contractor at no cost to the Government on rollers previously accepted and produced under the contract. Any deficiencies found as a result of the inspection comparison will be considered prima facie evidence that all rollers accepted prior to the completion of inspection comparison are similarly deficient unless evidence to the contrary is furnished by the contractor and such evidence is acceptable to the contracting officer.

4.6 Inspection of packaging. The preservation, packing, and marking shall be examined in accordance with the quality assurance provisions of MIL-R-3075.
