3. QUALITY ASSURANCE:
3.1 Certification. The contractor shall certify and maintain substantiating evidence that the product offered meets the requirements of this commercial item description/specification, and that the product conforms to the producer’s own drawings, specifications, standards, and quality assurance practices. The government reserves the right to require proof of such conformance prior to the first delivery and thereafter as may be otherwise provided for under the provisions of the contract.
3.2 Suppliers are encouraged to use quality control (QC) techniques that exhibit control over their processes (e.g. (Statistical Process Control) SPC techniques) as defined in American National Standards Institute (ANSI) Z1.1, Z1.2 and Z1.3/ American Society for Quality Control (ASQC) B.1, B.2, and B.3 that systematically reduce excess variations. If used, objective evidence shall be available that demonstrates overall measurement adequacy techniques and controls. These techniques shall ensure quality levels equal to, or greater than, those cited in applicable technical document or, herein.
End item inspections/testing may be used by the offeror or the Government representative, as a means to determine the effectiveness of the process quality controls. While in-process controls shall not be substituted for end item performance testing, they may be used when sampling for visual and dimensional conformance.
