All gauges used for service tests must have been calibrated within ________ days.

The requirement for gauges used in service tests to be calibrated within 60 days is crucial for safety and accuracy. Proper calibration ensures that the readings obtained during service tests are reliable and reflect the actual performance of the equipment being assessed. Regular calibration of gauges helps to maintain operational integrity, as it accounts for any potential drift or error that may occur over time due to environmental factors or wear.

The 60-day standard is generally established by relevant standards and practices in the fire service and apparatus testing. This timeframe strikes a balance between ensuring accuracy and providing practical guidelines for operations. Utilizing gauges that have not been calibrated within this period could lead to faulty readings, which may compromise the effectiveness of the service tests and ultimately affect safety during fire operations.

This timeframe also assists fire departments in maintaining a structured maintenance schedule, promoting a disciplined approach to equipment readiness and ensuring compliance with industry standards.
