30 CFR § 36.8
Date for conducting tests.
The date for acceptance of an application will determine the order of
precedence for testing when more than one application is pending, and the
applicant will be notified of the date on which tests will begin. If a
complete assembly, or component, or subassembly fails to meet any of the
requirements, it shall lose its order of precedence. However, if the cause of
failure is corrected, testing will be resumed after completing such test work
as may be in progress.
