This method can also be extended to diaphragm walls, barrettes, dams etc. R6760 one applies the results obtained using this standard is beyond its scope. The method does not give the exact type of flaw for example, inclusion, honeycombing, lack of cement particles, etc. Historical Version s – view previous versions of standard.

The data are used to confirm adequate concrete quality or identify zones of poor quality. The method does not give the exact type of defect for example, inclusion, honeycombing, lack of cement particles, etc.

No other units of measurement are r6760 in this standard. This test can assess to the integrity of the concrete mainly in the area bounded by the access ducts, 6d760 means typically inside the reinforcement cage. 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 satisfy the objectives of a particular test program.

Since the generated waves travel through the astk 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.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. 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.

Agencies that meet the criteria of Practice D are generally considered capable of competent and objective testing and inspection.

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