When authorized in writing by the CO, and if the contract includes Clause B–5: Certificate of Conformance, the supplier may use a Certificate of Conformance for supplies or services that would otherwise require inspection. The supplier’s signed certificate must be attached to the inspection or receiving report. By issuing a Certificate of Conformance, the supplier is certifying that it is furnishing the supplies called for by the contract and that the supplies are of the quality specified and conform in all respects with the contract requirements.
