Which term denotes citing NFPA documents without altering their content in regulations?

• A. Licensing Terms
• B. Local Laws
• C. Adoption by Reference
• D. Patent Holders

Answer: (C)

Adopting by reference means a regulation requires compliance with a standards document by citing it rather than reproducing its text verbatim. This approach keeps the regulation concise while binding the exact NFPA requirements, so the enforcement hinges on the standard as written by NFPA. By specifying the edition of the standard and incorporating it into law or regulation, authorities ensure consistent interpretation and updates—inspectors and designers know to follow the NFPA content itself, not a rewritten version. The other terms don’t fit because licensing terms imply permission to use, local laws are the broader legal rules that may or may not reference standards, and patent holders relate to intellectual property ownership rather than enforcing standards.
