No other units of measurement are included in this standard.

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 integrity of the concrete mainly in the area bounded by the access ducts, which means typically inside 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.

Plans, specifications, provisions, or combinations thereof prepared by a qualified engineer, and approved by the agency requiring the test smay provide additional requirements and procedures as needed to c6760 the objectives of a particular test program.

Reliable results depend on many factors; Practice D provides a means of evaluating some of those factors. The method does not give the exact type of defect for example, inclusion, honeycombing, lack of cement particles, etc.

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 6d760 to the inside of the reinforcement cage.

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.

How one applies the results obtained using this standard is beyond its scope. This method can also be extended to diaphragm walls, barrettes, dams etc. 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.

These notes and footnotes excluding those in tables and figures shall not be considered as requirements of the standard. Agencies that meet the criteria of Practice D are generally considered capable of competent and objective testing and inspection.
