Roland,
The AHJ cannot just willy-nilly accept non-code compliant items as it wants. That section does not allow the AHJ to disregard the code, that section simply "allows" the AHJ to accept and approve the installation on equipment and materials not addressed in the code.
Only by special permission is the AHJ allowed to "waive specific requirements in this Code or permit alternative methods where it is assured that equivalent objectives can be achieved by establishing and maintaining effective safety."
An "special permission" means *IN WRITING*:
From the definitions.
Special Permission. The written consent of the authority having jurisdiction.
