NOTE 11—Rejected pipe or tubes may be reworked in a manner acceptable to the purchaser. Basis of Application 6.
ASTM E213 – 14E1
No acceptable standardization repeatability can be provided in that case. It is important to note however that it is more difficult to obtain repeatable and accurate results with this technique because See 1: Current edition approved June 1, These may be specified upon contractual agreement between the using parties.
Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. Link to Active This link will always route to the current Active e123 of the standard.

This does not ensure detection of midwall discontinuities See Reference 5. Measurements may be made by optical, replicating, or other agreed upon techniques.
If indexed axial scanning is used, the same stability veri? Excessive surface roughness or scratches can produce signals that interfere with the examination. These procedures are intended to ensure that proper refraction angles and beam shapes are used to provide full volume coverage of pipes and tubes, including those with low ratios of outside diameterto-wall thickness, and to avoid spurious signal responses when examining small-diameter, thin-wall tubes.

ASTM E – 98 Standard Practice for Ultrasonic Examination of Metal Pipe and Tubing NO_PDF
The use of smaller notches by the examination agency is permissible, provided that concurrence is obtained from the contracting agency. The immersion method is almost always required for examining tubes for these uses. Artificial discontinuities consisting of longitudinal reference notches are employed as the primary means of calibrating the ultrasonic system.
When examination of heavy-wall pipes and tubes is required the focal length, refraction angle and included beam angle of focused axtm units shall be suitable for complete through-wall coverage See 5. Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility.
At the option of the testing agency, shallower notches may be used to provide a more stringent examination. A refraction angle of 45 degrees is typically used when examining pipe or tubes with a diameter-to-wall thickness ratio of no less than about 10 to 1.
The methods used for cleaning and preparing ee213 surfaces for ultrasonic examination shall not be detrimental to the base metal or the surface? The applicable edition of Practice E shall be speci? NOTE 1—The immersion method may include tanks, wheel search units, or systems that use streams or columns of liquid to couple the ultrasonic energy from the search unit to the material. Certain combinations of search unit size, frequency, thin wall thicknesses, and small diameters could cause generation of unwanted sound waves that may produce erroneous test results.
It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard.
NOTE 8—Identical conditions include all instrument settings, mechanical motions, search unit position and alignment relative to the pipe or tube, liquid couplant, and any other factors asttm affect the performance of the examination.
The response from the inner and outer surface notches should be as nearly equal as possible. The pipe or tubing to be examined and the search unit assembly shall have a rotating translating motion relative to each other such that a helical scan path will be described on the outer surface of the pipe or tube. Any of the apparatus types listed in Note 1 4.
In cases where the type of examination, material dimensions or other properties make the use of spherically or? Standardization of Apparatus Restandardize and reexamine the material if necessary, in accordance with the following procedures, unless otherwise speci? Rotate the tube without translation that is, without motion along its longitudinal axis and observe on the instrument display screen the motion of the notch signal away from any residual interface signal.
Active view current version of standard. It shall contain recordings of all standardizations and standardization checks and should be annotated to provide a positive correlation between examination record for each reject pipe or tube and the corresponding pipe or tube. Rust inhibitors, softeners, and wetting agents may be added to the couplant.
