4 QUALITY ASSURANCE PROVISIONS
4.1 Classification of inspections. The inspection requirements specified herein are classified as follows:
a. First article inspection (see 4.1.1).
b. Conformance inspection (see 4.8).
4.1.1 First article inspection. First article inspection, if not done by the manufacturer, shall be performed at a
laboratory acceptable to the procuring activity on sample units produced with equipment and procedures used in
production.
4.1.2 Conformance inspection. All finished shackles shall be carefully examined to determine conformance
problems with the specification with respect to workmanship, form, and dimensions.
4.1.3 Certification. Certification must be done with the procuring activity approval. The contractor shall certify
that the product offered meets the requirements of this document and manufactured to industry standards, and
quality assurance practices, and is the same as the product offered for sale in the commercial marketplace. 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
4.1.4 Responsibility for compliance. All items shall meet all requirements of sections 3, 4, and 5. The
inspection set forth in this specification shall become a part of the contractor's overall inspection system or quality
program. The absence of any inspection requirements in the specification shall not relieve the contractor of the
responsibility of ensuring that all products or supplies submitted to the Government for acceptance comply with all
requirements of the contract. Sampling inspection, as part of manufacturing operations, is an acceptable practice
to ascertain conformance to requirements, however, this does not authorize submission of known defective
material, either indicated or actual, nor does it commit the Government to accept defective material.
