The absence of any inspection requirements in the specification shall not relieve the contractor of the responsibility of assuring that all products or supplies submitted to the Government for acceptance comply with all requirements of the contract. Sampling in qua
22、lity conformance does not authorize submission of known defective material, either indicated or actual, nor does it commit the Government to acceptance of defective material. 4.1.2 Certification provisions. Certification shall include test data and results for each characteristic specified below. Ce
23、rtification shall be required for all material used in manufacturing the liners and prior to performing final acceptance inspection. Certification of Conformance shall include name of raw material producer, date of purchase, purchase order number, quantity, and all chemical, mechanical, -and physica
24、l analyses performed on the material. The following statement shall be included: “The undersigned, individually, and as the authorized representative of the contractor, warrants and represents that: All the information supplied above is true and accurate; the material covered by this certificate con
