2 Heat Treater Receipt of parts and work orders Purchase Orders After heat treating parts and validating hardness, take test specimen(s) to laboratory; do not return parts until notified to do so. Specimens and lab work order to laboratory
3 Laboratory Upon receiving specimen(s) and Purchase Order Purchase Order; any standards cited on Purchase Order or cited in letter stating Trinity Forge's testing specifications* Perform testing; produce report; email results to QA Assistant, QA Manager and Heat Treater.

All vendors kept apprised of process specifications they must meet
5 QA Assistant Upon receipt of test results via e-mail/fax Test results; Jobs Info Records results; verify "pass" or "fail"; enter results into Heat Code information. Results recorded in Heat Code information.
6 QA Assistant Upon receipt of test results via e-mail/fax Test results; Jobs Info If parts passed test(s), heat treater notified to return parts and close-out lab Purchase Order on computer; upon receipt of hard copy results scan into Part Certs.

* On June 18, 1996, a letter was sent to each Trinity Forge, Inc. approved testing vendor which explained that the specifications in the letter were to be followed as applicable unless a different one was stated on the work order in which case the work order specification would take precedence. A letter stating Trinity Forge's specifications will be sent to proposed vendors, as well as maintaining a current list of specifications to approved testing vendors.

Testing Parts Remaining In-House

Parts tested as-forged or at other points in the process rather than immediately after heat treat are processed similarly to the procedure given above for heat treated parts, except that the QA Manager assumes the role that the heat treater fills, keeping parts segregated (possibly at the lab) until receiving a "pass" report.
