If complying with Section 806.1 by meeting the requirements of Sections 806.1.2 through 806.1.7, a log of all materials used covered by those sections, showing the allowable limits and the actual product concentrations utilized in the project, shall be submitted prior to the final inspection. For compliance using Sections 806.1.2 through 806.1.7, project teams shall maintain all spec sheets for relevant materials, and shall make them available to the code official upon request. 806.1.1 Post-construction, pre-occupancy baseline IAQ testing.
