This specification covers the procedure for ultrasonic inspection of wrought titanium and titanium alloy products 0.25 inch (6.4 mm) and over in cross-sectional (thickness) or diameter.

When specifically requested by purchaser, this specification may be used for metals other than titanium.

This procedure has been used typically for locating internal defects, such as cracks, voids, spongy areas, and other structural discontinuities, which may or may not be exposed to the surface, but usage is not limited to such applications.
