30 CFR § 33.7
Date for conducting tests.
The date of 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 unit
or system fails to meet any of the requirements, it shall lose its order of
precedence. If an application is submitted to resume testing after correction
of the cause of failure, it will be treated as a new application and the
order of precedence for testing will be so determined.
