The basic structure of a museum storage room door should include the door frame, door leaf, anti-theft locks, deadbolt mechanisms, and daylight gates. Time locks and waterproofing devices should be included as necessary.
Two or more independent, operational anti-theft locks should be installed, and these locks must meet the requirements for anti-theft locks.
The latch mechanism's closing force is directly applied to the bolt, which should be able to freely open and close after withstanding a lateral pressure of 3,000N. If not directly applied to the bolt, the lateral pressure on the bolt should meet the requirements for normal use after undergoing a pressure test of 980N axially and 1,470N laterally. The door bolt mechanism should operate smoothly, and the installation area of the lock should be reinforced for protection.
The exterior surface of the museum storage room should be free of obvious bulges, dents, scratches, sharp edges, and coatings should not bubble, crack, wrinkle, or sag. All ferrous metal parts (except for bearings, stainless steel components, and reinforcing bars for concrete) should be treated with anti-corrosion measures, including spraying, electroplating, or equivalent methods. The color and texture should be uniform and consistent. When using different metals together, measures should be taken to prevent galvanic corrosion.
The storage room door of a museum should not have any gaps that allow a direct view into the vault.
The surfaces of door frames and doors should be flat, with a flatness of less than or equal to 3 mm/m².
The diagonal dimension deviation between the door frame and the door leaf should be no more than 2 millimeters for diagonals less than 2,500mm, and no more than 3 millimeters for diagonals greater than 2,500mm.
The installation of alarms, access control systems, and video surveillance devices on the museum's storage room doors should not affect the anti-dismantling performance of the vault doors.
