For materials not specifically covered by the code, supporting data necessary to verify compliance with the code must include _____.

Supporting data necessary to verify compliance with the code must include research reports when materials are not specifically covered. Research reports provide comprehensive evaluations conducted by reputable organizations, detailing the properties, performance, and compliance aspects of a material or system. Such reports are crucial as they offer detailed insights and testing results that demonstrate how a material performs according to established standards. They serve as a reliable source of information to validate the safety and effectiveness of materials, ensuring they meet the necessary code requirements.

In situations where specific materials are not addressed by existing codes, it is vital to rely on these reports to justify their use. While referenced standards, testing and listing, and the manufacturer's instructions are important, they may not encompass the depth of analysis provided by dedicated research reports, which often include peer-reviewed findings and extensive testing data tailored to unique materials or applications.
