of all inspection requirements as specified herein. Except as otherwise
specified in the contract or purchase order, the contractor may use his own or
any other facilities suitable for the performance of the Inspection require-
ments specified herein, unless disapproved by the Government. The Government
reserves the right to perform any of the inspections set forth in the
specification where such inspections are deemed necessary to assure supplies
and services conform to prescribed requirements.

of sections 3 and 5. The inspection set forth in this specification shall
become apart of the contractor's overall Inspection system or quality

all requirements of the contract. Sampling in quality conformance does not
authorize submission of known defective material, either indicated or actual,
nor does it commit the Government to acceptance of defective material.
