What do codes typically reference?

• A. Standards.
• B. Product catalogs.
• C. Weather data.
• D. Personal opinions.

Answer: (A)

Codes typically reference standards. This means the code relies on recognized, published criteria that define how things should be tested, rated, installed, and performed. In roofing and building practice, standards from organizations such as ASTM, NFPA, and AAMA provide the concrete methods and performance requirements that codes adopt. By pointing to these standards, codes ensure consistency, safety, and compatibility across products and projects, and they can be updated through changes in the standards rather than rewriting the code itself. Product catalogs are marketing materials and don’t provide validated test methods or performance criteria. Weather data informs design loads and conditions but isn’t used as the official reference framework in codes. Personal opinions aren’t part of the formal regulatory foundation.
