   B.   Supplemental Documents: Due to the complexities of the construction industry, the International Residential Code and the International Building Code make reference to additional documents to provide clarification of intent and potential options for code compliance. When this occurs, the referenced documents shall be treated as an integral part of the prevailing Building Code. Should a conflict occur between the Building Code and a referenced document, the most stringent regulation of the two shall apply. Documents approved by testing agencies (American Society for Testing and Materials (ASTM), International Code Council (ICC), Underwriters Laboratories (UL), etc.) and installation instructions from material manufacturers are examples of sources referenced to define approved construction practices. Before using any material or methods of application not specifically mentioned in the International Residential Code or the International Building Code, the building official should be contacted.
   C.   Tests: The building official has the authority to require tests to substantiate the claim that an alternative material or method of application is equivalent and meets the intent of the international codes. Any tests must be in compliance with those standards specified in the international codes or other recognized standards approved by the building official. The costs of any test will be borne by the proponent seeking the approval of the alternative material or method of application. Testing will be conducted by an agency approved by the building official or by the building official, in the building official's sole discretion.
