3.2.1 Pre-Functional Performance Test Checklists

3.2.1.1 Pre-Functional Performance Test Checklists shall be performed for the items indicated in Appendix A. Deficiencies discovered during these checks shall be corrected and re-inspected in accordance with the applicable contract requirements.

3.2.2 Functional Performance Tests

3.2.2.1 Functional Performance Tests shall be performed for the items indicated in Appendix B.

Functional Performance Tests shall begin only after all Pre-Functional Performance Test Checklists have been successfully completed. Tests shall prove all modes of the sequences of operation, and shall verify all other relevant contract requirements. Tests shall begin with equipment or components and shall progress through subsystems to complete systems. Upon failure of any Functional Performance Test item, the Contractor shall correct all deficiencies in accordance with the applicable contract requirements. The item shall then be retested until it has been completed with no errors.
