When testing hose, maintain test pressure in accordance with NFPA 1962 for ______ minutes.

When testing hose, maintain test pressure in accordance with NFPA 1962 for ______ minutes.

• A. 1
• B. 3
• C. 2
• D. 5

Answer: (B)

Hydrostatic testing checks that hose and its couplings can stay intact under sustained pressure. NFPA 1962 outlines how hoses should be tested, including how long to hold the test pressure. The standard specifies maintaining the test pressure for three minutes. This duration is long enough to reveal slow leaks, weak spots, or coupling failures, while remaining practical for routine maintenance. By holding pressure for this period, you verify the hose can perform under conditions that exceed normal service pressure, ensuring reliability when needed.
