Acceptance testing requires visual inspection to ensure installation per plans according to which NFPA standard and chapter?

• A. NFPA 13, Chapter 5
• B. NFPA 11, Chapter 11
• C. NFPA 25, Table 11.1.1.2
• D. NFPA 70, Article 520

Answer: (B)

Acceptance testing is the stage where you verify the system was installed as designed and can operate correctly, and a visual inspection is a key part of that verification. The standard that specifically directs this approach for foam fire-protection systems is NFPA 11, Chapter 11, which covers acceptance testing and requires visually confirming that equipment, piping, and components are installed according to the plans. This ensures things like correct locations and orientations, proper fittings, labeling, and accessibility match the design drawings before the system is accepted. The other options relate to different systems or phases—NFPA 13 deals with sprinkler design and installation, NFPA 25 covers inspection and maintenance after installation, and NFPA 70 Article 520 concerns electrical installations for stages—so they don’t address the acceptance-testing visual verification in the same way.
