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

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

ast 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 does not give the exact type of flaw for example, inclusion, honeycombing, lack of cement particles, etc.

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

ASTM D6760 – 16

This test can assess to the e6760 of the concrete mainly in the area bounded by the access ducts, which means typically inside the reinforcement cage. The data are used to confirm adequate concrete quality or identify zones of poor quality.

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. 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 is most applicable when performed in tubes that are installed during construction. Agencies that meet the criteria of Practice D are generally considered capable of competent and objective testing and inspection. 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.

Active view current version of standard. 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.

Reliable results depend on many factors; Practice D provides a means of evaluating some of those factors. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

No other units of measurement are included in this standard. Users of this standard are cautioned that compliance with Practice D does not in itself assure reliable results.

Link to Active This link will always route to the current Active version of the standard. This method can also be extended to diaphragm walls, barrettes, dams 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 attached to the inside of the reinforcement cage.
