34、andpurchaser, pipe or tube may be tested to 112 times theallowable fiber stress given in 7.3.1.7.3.3 Each pipe or tube shall be subjected to the hydrostatictest, or, in lieu of this test, a nondestructive eddy current testmay be used at the manufacturers option. If eddy currenttesting is used, the f

The eddy-currentexamination referenced in this specification has the capabilityof detecting significant discontinuities, especially of the shortabrupt type.(1) Unless o
36、therwise specified the calibration standard shallcontain, at the option of the manufacturer, any one of thefollowing discontinuities to establish a minimum sensitivitylevel for rejection. The discontinuity shall be placed in the weldif visible.(2) Drilled HoleA hole not larger than 0.031 in. (0.79mm
37、) in diameter shall be drilled radially and completelythrough the wall, care being taken to avoid distortion of thematerial while drilling.(3) Transverse Tangential NotchUsing a round file ortool with a14 in. (6 mm) diameter, a notch shall be filed ormilled on the tube outside diameter tangential to
38、 the surfaceand transverse to the longitudinal axis of the material. Saidnotch shall have a depth not exceeding 1212 % of the specifiedwall thickness of the material, or 0.004 in.

39、 At the beginning of each production run or log.(2) After every4horless during testing.(3) At the end of each production run or lot.(4) At any time malfunctioning is suspected, or theequipment has been left unattended.(5) If, during any check, the equipment fails to pick up thestandard defects in th
40、e calibration standard, the instrument testmust be recalibrated and all material tested since the last checkshall be reexamined.7.3.3.3 Acceptance and RejectionMaterial producing asignal equal to or greater than the calibration imperfection shallbe subject to rejection.(1) Test signals produced by i
41、mperfections that cannot beidentified or produced by cracks or crack-like imperfectionsshall result in rejection of the tube, subject to rework, andretest.(2) If the imperfection is judged as not fit for use, the tubeshall be rejected, but may be reconditioned and retestedproviding the dimensions re
42、quirements are met. To be ac-cepted, retested material shall meet the original electric testrequirements.(3) If the imperfection is explored to the extent that it canbe identified and the pipe or tube is determined to be fit for use,the material may be accepted without further test providing theimpe
