Unless othervise specified in thecontract or purchase order, the contractor is responsible for the performance ofall inspection requirements (examinations and tests) as specified herein. Exceptas otherwise specified in the

36、 contract or purchase order, the contractor may usehis own or any other facilities suitable for the performance of the inspectionrequirements specified herein, unless disapproved by the Government. TheGovernment reserves the right to perform any of the inspections set forth in thisspecification wher

37、e such inspections are deemed necessary to ensure supplies andservices conform to prescribed requirements.4.1.1 esuonsibilitv for compliance.
