Before the first use of any packaging for the shipment of licensed material:
(A) The licensee shall ascertain that there are no cracks, pinholes, uncontrolled voids, or other defects that could significantly reduce the effectiveness of the packaging;
(B) Where the maximum normal operating pressure will exceed thirty-five kilopascal (five pounds force per square inch) gauge, the licensee shall test the containment system at an internal pressure at least fifty per cent higher than the maximum normal operating pressure, to verify the capability of that system to maintain its structural integrity at that pressure; and
(C) The licensee shall conspicuously and durably mark the packaging with its model number, serial number, gross weight, and a package identification number assigned by the United States nuclear regulatory commission. Before applying the model number, the licensee shall determine that the packaging has been fabricated in accordance with the design approved by the United States nuclear regulatory commission.
