The maximum length for fire hose service testing is 90 m (300 ft). This standard is established to ensure that fire hoses are tested under conditions that closely mimic their operational environment while remaining manageable in length for personnel conducting the testing. Longer lengths can introduce variables such as increased friction loss and pressure drop, which can affect the accuracy of the test results. The 90 m (300 ft) limit allows for effective testing without compromising the integrity of the hose or safety of the firefighters conducting the test. This specification is critical in maintaining the reliability and performance of fire hoses during emergency situations.
