Which statement about standpipe components and hardware in relation to AHJ guidelines is correct?

• A. Inspected only by the fire department
• B. Listed and approved by the authority having jurisdiction
• C. Certified by the NFPA
• D. Not subject to listing

Answer: (B)

Standpipe components must be listed by a recognized testing laboratory and approved by the authority having jurisdiction before use. Listing confirms the product has been tested to applicable standards and is suitable for its intended purpose, while approval by the AHJ means the specific project has been reviewed and permitted to install that listed equipment. NFPA 14 relies on this combination to ensure compatibility, reliability, and safety of standpipe systems in the field.

This is not merely about fire department inspections, which are important for oversight but do not substitute for formal listing and AHJ approval. NFPA standards do not certify equipment themselves—the certification typically comes from independent testing laboratories, and the AHJ grants approval for the installation based on those listings. And components that are not listed are not acceptable for use in standpipe systems.
