pressures involved and the unpredictable results.
(c) Install test tee and hydrostatic pump.
(d) Subject hose to a pressure of 250 psig and hold for two minutes.
(e) Release pressure from hose.
(f) Disconnect hydrostatic pump; test tee and seal.
(g) Drain water from hose.
(h) Discard hose that fails this test.
(i) Record test in hose log or install metal tag on hose with testing activity, date tested, and test

same date of manufacture.
(b) Cut a 36-inch test specimen from each length selection.
(c) Install 0-5000 psi pressure gage in supply line of hydrostatic pressure source.
(d) Connect one end of test specimen to hydrostatic pressure source.
(e) Purge specimen of air.
