Hydrostatic Test - Each tube shall stand, without showing evidence of leakage, an internal hydrostatic pressure
sufficient to subject the material to a fiber stress of 7000 psi, determined by the following equation for thin hollow
cylinders under tension. The tube need not be tested at a hudrostatic pressure of over 1000psi unless so specified.
P = 2St/(D-0.8t) where:
P = hydrostatic pressure, psig.
t = thickness of tube wall, in.
D = outside diameter of the tube. in., and
S = allowable stress of the material, psi.
