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. The accelerometer s should be placed at or near the pile head and shall have their sensitive axis parallel with the pile axis.

The method works best on solid concrete sections, and has limited application to unfilled steel pipe piles, H piles, or steel sheet piles.

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. Reliable results depend on many factors; Practice D provides a means of evaluating some of those factors. Alternatively, the hammer may have an.

ASTM D 5882-16 Compliance Statement

This standard may involve hazardous materials, operations, and equipment. Current edition approved May 1, A hammer with a very hard plastic tip can induce a short input force pulse without causing local pile damage. A superscript epsilon e indicates an editorial change since f5882-07 last revision or reapproval.

This standard does not purport to address all of the safety concerns, if any, associated with its use. Sorry, this content is unavailable because your browser does not support iframes. How one applies the results obtained using this d588-07 is beyond its scope.

Active view current version of standard. If damage is suspected during use, recalibrate or replace the accelerometer.

This system, along with its associated software, uses only the time domain information in the data for the interpretation of reflections. The OE Website is loaded with Tech Brief and project photos using the equipment shown on this website.

No other units of measurement are included in this standard. Sonic Echo-Impulse Response is used for low strain integrity testing of piles and determination of deep foundation length. Contact Olson Instruments when adding on to an existing system, or purchasing multiple systems as some of the components are common d58820-7 other test methods.

These notes and footnotes excluding those in aetm and figures shall not be considered as requirements of the standard. This standard does not purport to address all of the safety concerns, if any, associated with its use. 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. Reliable results depend on many factors; Practice D provides d5882-0 means of evaluating some of those factors.

Olson offers Sonic Echo systems for use with zstm different platforms as shown in the chart below. 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.

ASTM D – 07 Standard Test Method for Low Strain Impact Integrity Testing of Deep Foundations

The hammer may have a force load cell between the tip and hammer body. The time domain record is then evaluated for pile integrity. Note 1 he quality asmt 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. All of Olson Instruments have been researched, tested, and used on-site daily by our sister company, Olson Engineeringworld reknowned for NDT consulting.

No other units of measurement are included in this standard. Aetm to Active This link will always route to the current Active version of the standard. How one applies the results obtained using this standard is beyond its scope. Training may be available at your location by one of our agents upon special arrangement.

This test method is applicable to long structural aatm that function in a manner similar to any deep foundation units d58820-7 as driven piles, augeured piles, or drilled shaftsregardless of their method of installation provided that they are receptive to low strain impact testing.

NDT System Add-On — Sonic Echo/Impulse Response

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.

Accelerometers shall be linear to at least 50 g. Alternatively, velocity or displacement axtm may be used to dd5882-07 velocity data, provided they are equivalent in performance to the specified accelerometers. 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. Last previous edition approved in as D — The impact should be applied axially to the pile normally on the pile head.

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