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.
