Testing should therefore be performed as soon as practical in order to avoid debonding issues.

How one applies the results obtained using this standard is beyond its scope. How one applies the results obtained using this standard is beyond its scope.

If defects are detected, then further investigations should be made by excavation or coring the concrete as appropriate, or by other testing such as Test Method DD or Dand measures taken to remediate the structure if a defect is confirmed. The method is limited primarily to testing the concrete between the access ducts and thus gives little information about the concrete outside the reinforcement cage to which the access ducts are attached when the tubes are attached to the inside of the reinforcement cage.

The quality of the result produced by this standard is dependent on the competence of the personnel performing it, and the suitability of the equipment and facilities used. These notes and footnotes excluding those in tables and figures shall not be considered as requirements of the standard. No other units of measurement are included in this standard.

The data are used to confirm adequate concrete quality or identify zones of poor quality. Reliable results depend on many factors; Practice D provides a means of evaluating some of those factors. This method is most applicable when performed in tubes that are installed f6760 construction.

Users of this standard are cautioned that compliance with Practice D does not in itself assure reliable results.

Since the generated waves travel through the concrete around the access duct, unless a flaw is massive enough and very near to the access duct it may not be detected by this method. This method can also be extended to diaphragm walls, barrettes, dams etc.

This test can assess to the aatm of the concrete mainly in the area bounded by the access ducts, which means typically inside the reinforcement cage.
