During the hose pressure test, which steps are required?

Hydrostatic testing checks hose integrity by using water under pressure to reveal leaks. The required steps reflect this: fill the hose with water for a short period, then pressurize it to the specified test level and look for leaks. After the test, dry the hose at a controlled temperature, not exceeding 150°F, before marking it and returning it to service. This approach relies on water to reveal weak spots under pressure and protects the hose from heat damage during post-test drying. Using air instead of water wouldn’t reliably show leaks and carries different safety concerns, the procedure isn’t to dry the hose first or then heat it to extreme temperatures, and simply submerging the hose doesn’t apply the pressure needed to test its strength.
