Tubes may be tested in the final drawn， annealed， or heat-treated temper or in the drawn temper before the final anneal or heat treatment unless otherwise agreed upon by the supplier and the purchaser. The purchaser may specify either of the tests in Hydrostatic Test or Pneumatic Test as an alternative to the eddy-current test.
Eddy-Current Test—Each tube shall be passed through an eddy-current testing unit adjusted to provide information on the suitability of the tube for the intended application. Testing shall follow the procedures of Practice E243.
P = hydrostatic pressure， psig [MPa];
t = thickness of tube wall， in. [mm];
D = outside diameter of the tube， in. [mm]; and
S = allowable stress of the material， psi [MPa].
