Section 3. Approved Materials and Methods of Construction or Installation/Operation. The provisions of this Code are not intended to prevent the use of any design, material, or method of installation or operation not specifically prescribed by this Code, provided any such alternate has been approved. The building official may approve any such proposed alternate providing he finds that it:
a. provides at least approximate equivalence to that applicable specific requirements of this Code
b. is otherwise satisfactory and complies with the intent of this Code; or
c. has been designed or approved by a registered professional engineer and content and function promotes the intent of this Code.

4. For the purposes of this Code, quartz lamps shall not be considered an incandescent light source.
