Contractor certification. The contractor shall certify and maintain
substantiating evidence that the product offered meets the salient characteristics of this
Commercial Item Description, 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 first delivery and
thereafter as may be otherwise provided for under the provisions of the contract.
Metric products. Products manufactured to metric dimensions will be
considered on an equal basis with those manufactured using inch-pound units,
provided they fall within specified tolerances using conversion tables contained in the
latest revision of
ASTM E 380, and all other requirements of this Commercial Item Description are met.
If a product is manufactured to metric dimensions and those dimensions exceed the
tolerances specified in the inch/pound units, a request should be made to the
contracting officer to determine if the product is acceptable. The contracting officer
has the option of accepting or rejecting the product.
Regulatory requirements. The offeror/contractor is encouraged to use
recovered materials IAW Public Law 94-580 to the maximum extent practical.
