ASTM D6760 – 16

The method does not give the exact type of defect for example, inclusion, honeycombing, lack of cement particles, etc. This method is most applicable when performed in tubes that atm installed during construction. How one applies the results obtained using this standard is beyond its scope. 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.

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. The data are used to confirm adequate concrete quality or identify zones of poor quality. Users of this standard are cautioned that compliance with Practice D does not in itself assure reliable results. How one applies the results obtained using this standard is beyond its scope. Testing should therefore be performed as soon as practical in order to avoid debonding issues.

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

Reliable results depend on many factors; Practice D provides a means of evaluating some of those factors. No other units of measurement are included in this standard.

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.

If defects are detected, then further investigations should be made by excavation or coring the s6760 as appropriate, or by other testing such as Test Astn DD or Dand measures taken to remediate the structure if a defect is confirmed.

Active view current version of standard. The method is limited primarily to testing the concrete between the access ducts and thus gives little ashm 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. No other units of measurement are included in this standard. Historical Version s – view previous versions of standard.
