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 r5882-07regardless of their method of installation provided that they are receptive to low strain impact testing. It is the responsibility of the user of this standard to establish appropriate safety and health practices and deter- mine the applicability of regulatory d5882-07 prior to use.
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. Active view current version of standard.
Significance and Use 4.
No other units of measurement are included in this standard. Link to Active This link will always route to the current Active version of the standard. This standard does not purport to address all of the safety concerns, if any, associated with its use.
The method works best on solid concrete sections, and has limited application to unfilled steel pipe piles, H piles, or steel sheet piles. Enviado por Vitor flag Denunciar.
How one applies the results obtained using this standard is beyond its scope. Accelerometers shall be linear to at least 50 g. D — 07 Standard Test Method for Low Strain Impact Integrity Testing of Deep Foundations1 This standard is issued under the fixed designation D ; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision.
The accelerometer s should be placed at or near the pile head and shall have their sensitive axis parallel with the pile axis. The Sonic Echo-Impulse Response system is designed to determine the length and integrity of foundations when the top or part of the upper side of the foundation is accessible.

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. These data assist evaluation of pile integrity and pile physical dimensions that is, cross-sectional area, lengthcontinuity, and consistency of the pile material, al- though evaluation is approximate and not exact.

NDT System Add-On — Sonic Echo/Impulse Response
This standard does not purport to address all of the safety concerns, if any, associated with its use. D55882-07 previous edition approved in as D — This method works best for columnar type foundations such as piles and drilled shafts, but has also been used successfully on mat foundations, abutment walls, and similar structures. Alternatively, velocity or displacement transducers may be used to obtain velocity data, provided they are equivalent in performance to the specified accelerometers.
Sonic Echo-Impulse Response is used for low strain integrity testing of piles and determination of deep foundation length.
No other units of measurement are included in this standard. The impact should be applied axially to the pile normally on the pile head. Training may be available at your location by one of our agents upon special arrangement. 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. Reliable results depend on many factors; Practice D provides a means of evaluating some of those factors.
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. The hammer may have a force load cell between the tip and hammer body. The time domain record is then evaluated for pile integrity. Users of this test method are cautioned that compliance with Practice D does not in itself assure reliable results.
Olson Instruments sells the base model SE-1 system that exclusively uses the Sonic Echo methodology without the Impulse Response analysis.
All of Olson Instruments have been researched, tested, and used on-site daily by our sister company, Olson Engineeringworld reknowned for NDT consulting.
ASTM D 5882-16 Compliance Statement
If damage is suspected during use, recalibrate or replace the accelerometer. NOTE 1—he quality of the result produced by this test method is dependent e5882-07 the competence of the personnel performing it, and asfm suitability of the equipment and facilities used. 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. Users of this test method are cautioned that compliance with Practice D does not in itself assure reliable results.
ASTM D – 07 Standard Test Method for Low Strain Impact Integrity Testing of Deep Foundations
Current edition approved May 1, Alternatively, the hammer may have an. Reliable results depend on many factors; Practice D provides a means of evaluating some of those factors. This system, along with its associated software, uses only the time d588207 information in the data for the interpretation x5882-07 reflections. 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.
