HOSE TESTING

Hose Test Appliances

• Check condition of hose test machine.• Make sure caps are on fire hose outlet

connection• Pressure up to 10% higher than service test

needed. 330• Hold pressure for 3 minutes with pump off.• TEST OF MACHINE DONE

Time to test hose

• Apply nozzle to no more than 300 ft of hose.• Charge hose to 45 psi, make sure to discharge

air from line. Check all couplings tighten with spanner.

• Raise pressure no more than 15psi per sec. until desired pressure is reached.

• Allow 1 minute of stabilization per 100ft• Hold service test pressure for 3 minutes

INFO

• If you walk the layout stay 15 ft from the left side of the hose. The left side is defined as the side that is left when facing the free end

• Never stand in front of the free end of the hose , the right, and no less than 15 ft on the left side. Never straddle the hose.

belt tie in or rope hose tool at a point 10 to 15 in from the coupling

• Apply nozzle to no more than 300 ft of hose.• Charge hose to 45 psi, make sure to discharge

air from line. Check all couplings tighten with spanner.

• Raise pressure no more than 15psi per sec. until desired pressure is reached.

• Allow 1 minute of stabilization per 100ft• Hold service test pressure for 3 minutes

OTHER HOSE

• BOOSTER HOSE• 110 percent of maximum working pressure or• normal highest pressure used in the system

• SUCTION HOSE• Attached to suction source• Free end sealed with disk and connected to accurate

vacuum measuring instrument.• A 22 in. mercury vaccum shall be developed.• Hold for 10 mins.
