of contract and prior to production, at a location acceptable to the Government. First article inspection
shall be performed on sample units which have been produced with equipment and procedures normally
used in production. First article approval is valid only on the contract under which it is granted, unless
extended by the Government to other contracts. The first article sample is intended to provide necessary
information to establish the propellant granulation needed to meet the required ballistic performance
