Where leakage testing results that are borderline (passing but within 10 percent of the acceptance criterion) are accepted, the Engineer may require a re-test during the warranty period to confirm that seasonal temperature cycles, building settlement, and sealant aging have not caused the leakage rate to increase to a failing value. Re-testing under warranty shall be at the Contractor's expense. The Contractor shall maintain access to all tested duct sections throughout the warranty period by keeping access doors clear of finishes, equipment, and storage.
