Air hose burst test.
Clear area before conducting test to avoid injury to personnel.
Ensure all air has been removed from hose before conducting test.
This test not conducted until five years of age and then every year there after until failure.
Randomly select one length of hose from each lot of hose on board. A lot is defined as all hose with same
date of manufacture.
Cut a 36 inch test specimen from each length selection.
Install 0-5000 psi pressure gage in supply line of hydrostatic pressure source.
Connect one end of test specimen to hydrostatic pressure source.
Purge specimen of air.
Seal open end of specimen.
Lay specimen out straight on a flat surface.
Observe pressure gage; increase hydrostatic pressure SLOWLY until specimen bursts; secure hydrostatic
Minimum acceptable burst pressure is 2400 psi.
If specimen fails burst test, each hose bearing the same date is to be removed from diving service.
If specimen passes burst test, each hose from the same lot and the unburst tested section of specimen
hose may be continued in service until the next annual testing period.
Remove specimen from hydrostatic pressure source.
Remove pressure gage.
Reinstall coupling and new clamps on unburst tested section of specimen hose if specimen passes burst
Roughen cut end of hose with sandpaper.
