Final answer:
In any specific case where different sections of a code specify different requirements, the most restrictive requirement governs to ensure the highest level of safety and compliance.
Step-by-step explanation:
When different sections of a code specify different materials, methods of construction, or other requirements, the part of the code that is the most restrictive shall govern. This means that when there is a conflict between requirements, the requirement that imposes the stricter standard or limitation takes precedence. The rationale behind this rule is to ensure the highest level of safety and compliance with the standards deemed necessary for construction and materials.
