C. 100% successful performance during Acceptance Testing is expected, based on the Subcontractor's Insulation Testing Documentation and 100% Test

Certification required, in accordance with NFPA 72. In the event of system performance inconsistent with the Subcontractor's testing certifications, Fermilab will make a determination as to whether or not the test results constitute failure of the Acceptance Test. Failure of the Acceptance Test shall invalidate the Subcontractor's System Certification, in which case recertification (including 100% Subcontractor retesting) and a repeat of the

Acceptance Test shall be required at no additional cost to Fermilab.
