The method works best on solid concrete sections, and has limited application to unfilled steel pipe piles, H piles, or steel sheet piles. The software then automatically calculates the transfer and coherence functions, which may be useful for data quality analysis as well as providing further information about reflections within the structure.
No other units of asfm are included in this standard. Link to Active This link will always route to the current Active version of the standard. Current edition approved May 1, These data assist evaluation of pile integrity and pile physical dimensions that is, asttm area, lengthcontinuity, and consistency of the pile material, al- though evaluation is approximate and not exact.
ASTM D 5882-16 Compliance Statement
This test method is applicable to long structural elements that function in a manner similar to any deep foundation units such as driven piles, augeured piles, or drilled shaftsregardless of their method of installation provided that they are receptive to low strain impact testing.
This standard does not purport to address all of the safety concerns, if any, associated with its use. Olson Instruments sells the base model SE-1 system that exclusively uses the Sonic Echo methodology without the Impulse Response analysis. Last previous edition approved in as D — If damage is suspected during use, recalibrate or replace d588-07 accelerometer.
Training may be available at your location by one of our agents upon special arrangement. Contact Olson Instruments when adding on to an existing system, or purchasing multiple systems as some of the components are common to other test methods.
The hammer may have a force load cell between the tip and hammer body. The OE Website is loaded with Tech Brief and project photos using the equipment shown on this website. Note 1 he quality of the result produced by this test method is dependent on the competence of the personnel performing it, and the suitability of the equipment and facilities used.
It is the responsibility of the user of dd5882-07 standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations wstm to use.
ASTM D – 07 Standard Test Method for Low Strain Impact Integrity Testing of Deep Foundations
Click here for Agents. Sonic Echo-Impulse Response is used for low strain integrity testing of piles and determination of deep foundation length. This test method is applicable to long structural elements that function in a manner similar to any deep foundation units such as driven piles, augeured piles, or drilled shaftsregardless of their method of installation provided that they are receptive to low strain impact testing.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. It is the responsibility of the user of this standard to establish appropriate safety and health practices and deter- mine the applicability of regulatory limitations prior to use.
Alternatively, the hammer may have an. A hammer with a very hard plastic tip can induce a short input force pulse without causing local pile damage. This test method will not give information regarding the pile bearing capacity.
NDT System Add-On — Sonic Echo/Impulse Response
A superscript epsilon e indicates an editorial change since the last revision or reapproval. Originally approved in Significance and Use 4.
The accelerometer s should be placed at or near the pile head d8582-07 shall have their sensitive axis parallel with the pile axis. This system, along with its associated software, uses only the time domain information in the data for the interpretation of reflections.
The impact should be applied axially to the pile normally on the sstm head. This system and its associated methodology can be used on both new and existing foundations and is performed by impacting the foundation and recording echoes from a defect or the foundation bottom with a nearby receiver s.
