Hose testing equipment must be calibrated within how many months?

• A. 6 Months
• B. 24 Months
• C. 36 Months
• D. 12 Months

Answer: (D)

Regular calibration of hose testing equipment is essential to keep readings accurate. Over time, gauges and related devices can drift due to use, temperature changes, and wear, and relying on uncalibrated measurements can lead to unsafe or invalid test results. Calibrating at least once per year provides a practical, safe standard that matches typical maintenance practices in fire service. Calibration more often than annually isn’t usually necessary unless there’s heavy use or noticeable drift, while extending beyond a year increases the chance of undetected inaccuracies. So, calibrating within one year is the standard requirement.
