SECURITY OF TEST MATERIALS.

(a) On completing each test, the general custodian of election records shall place the test materials in a container provided for that purpose and seal the container in a manner that prevents opening without breaking the seal. The general custodian of election records and at least two members of the testing board shall sign the seal.

(b) The test materials shall remain sealed for the period for preserving the precinct election records.

(c) The container may not be unsealed unless the contents are necessary to conduct a test under this subchapter or a criminal investigation, an election contest, a request for public inspection under Subsection (d), or any other official proceeding under this code. If the container is unsealed, the authority in charge of the proceeding shall reseal the contents when not in use.

(d) The test materials are not available for public inspection until the first day after the final canvass of the election is completed. The sealed container containing the test materials may be unsealed to allow for public inspection of the records and shall be resealed after the inspection of those records is completed.
