Which hose size and test pressure combination is used for testing 44mm hose?

• A. 44mm, 2100kPa 3mins
• B. 65mm, 2100kPa 3mins
• C. 65mm, 3500kPa 3mins
• D. 125mm, 1400kPa 3mins

Answer: (A)

Testing a fire hose relies on hydrostatic testing to verify the integrity of the hose under pressure. For a 44 mm hose, the standard procedure is to fill the hose with water, seal the ends, and pressurize it to 2100 kPa (about 21 bar) and hold for 3 minutes. This pressure provides a safe margin above typical operating pressures while being high enough to reveal leaks, weak seams, or bursting points without overstressing the hose walls.

So the combination of 44 mm diameter with 2100 kPa for 3 minutes is the one that matches the established testing standard for this size. The other options mix different diameters or inappropriate pressures, which would not align with the tested and accepted procedures for a 44 mm hose.
