Nothing in this code is intended to prevent the
use of systems, methods, or devices of equivalent or superior
quality, strength, fire resistance, effectiveness, durability, and
safety over those prescribed by this code. Technical documentation
shall be submitted to the Authority Having Jurisdiction
to demonstrate equivalency. The Authority Having
Jurisdiction shall have the authority to approve or disapprove
the system, method, or device for the intended purpose. [HCD 1] (See 1.8.7)
However, the exercise of this discretionary approval by the Authority Having Jurisdiction shall have no effect beyond the jurisdictional boundaries of said Authority Having Jurisdiction. An alternate material or method of construction so approved shall not be considered as in accordance with the requirements, intent, or both of this code for a purpose other than that granted by the Authority Having Jurisdiction where the submitted data does not prove equivalency.

the test procedure.
The Authority Having Jurisdiction shall have
the authority to require tests to be made or repeated
where there is reason to believe that a material or
device no longer is in accordance with the requirements
on which its approval was based.
