The relative response from the inner and outer surface notches shall be as nearly equal as possible by selection of the pair of adjacent inner surface and outer surface notch signal nodes are observed.
Artificial reflectors consisting of longitudinal, and, when specified by the using party or parties, transverse reference notches placed on the surfaces of a reference standard are employed as the primary means of standardizing the ultrasonic system.
Some differences in this procedure are required, as described below, depending upon whether the contact or immersion technique is employed. 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.
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.
Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. 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 that affect the performance of the examination.
An independent channel or channels of instrumentation shall be employed to individually monitor the responses from the longitudinal and, when required, transverse oriented search units. If, upon ultrasonic reexamination of the reworked pipe or tube, no rejectable indications are detected, the material should be considered as having passed the ultrasonic examination.

Note— Alternatively, set-up on the inner surface notch may be performed before set-up on the outer surface notch, as described in step h above. The SI equivalents atsm in parentheses and may be approximate. Set the position and duration of the instrument alarm gate to include both of these signals.
This standard does not purport to address all of the safety concerns, if any, associated with its use. Artificial discontinuities consisting of longitudinal reference notches are employed as the primary means of calibrating the ultrasonic system. For awtm tubes, support mechanisms must be used in the examination station to prevent any transverse motion with respect to the search unit zstm during scanning.
The applicable edition of Practice E shall be speci? If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below. For very large-diameter material where this requirement is found to be impractical search units of other focal lengths or unfocused units may be used.
For thick-wall tubes a lower astn angle may be required for examination of the entire thickness 5. The SI equivalents are in parentheses and may be approximate.

The values stated in inch-pound units are to be regarded axtm standard. The amplitude should decrease and increase as successive re? Restandardize the equipment in accordance with When examination of heavy-wall pipes and tubes is required the focal length, refraction angle and included beam angle of focused search units shall be suitable for complete through-wall coverage See 5.
The methods used for cleaning and preparing the surfaces for ultrasonic examination shall not be detrimental to the base metal or the surface? Summary of Practice 4. The reference pipe or tube shall be free of discontinuities or other conditions producing indications that can interfere with detection of the reference notches.
The practice or standard used and its applicable revision shall be identi? The SI equivalents are in parentheses and may be approximate. This does not ensure detection of midwall discontinuities See Reference 5.
The response from the inner and outer surface notches should be as nearly equal as possible. Standard ASTM E Standard for Ultrasonic Testing of Metal Pipe Tube This practice covers a procedure for detecting discon- tinuities in metal pipe and steel tubing during a volumetric exami- nation using ultrasonic methods.
No acceptable standardization repeatability can be provided in that case. The incident and refracted beams in these cases are pictured as being generated by a cylindrically focused immersion search unit. A number in parentheses indicates the year of last reapproval.
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.
Make these checks prior to any examination run, prior to equipment shutdown after an examination run, and at least every hour during continuous equipment operation. Record the peak amplitude of the signal from the inner surface notch. Active view current version axtm standard.
