Which classification is assigned to a representative from an independent testing laboratory?

• A. M Manufacturer
• B. U User
• C. RT Applied Research/Testing Laboratory
• D. E Enforcing Authority

Answer: (C)

Independent testing labs provide objective test data and evaluation for NFPA compliance. The representative from such a lab is classified as Applied Research/Testing Laboratory (RT). This label signals their role: they conduct tests, analyze results, and present independent findings on equipment and systems, separate from manufacturers or building owners. It’s different from a manufacturer’s representative (who promotes products), a user’s representative (who represents the owner), or an enforcing authority (who enforces codes and conducts inspections). The RT designation helps ensure the credibility and impartiality of test results used to verify that standpipe components meet the standard.
