The data are evaluated usually in the frequency domain. Olson offers Sonic Echo systems for use with three different platforms as shown in the chart below.

Users of this test method are cautioned that compliance with Practice D does not in itself assure reliable results. 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. If damage is suspected during use, recalibrate or replace the accelerometer. Sonic Echo-Impulse Response is used for low strain integrity testing of piles and determination of deep foundation length.

These notes and footnotes excluding those in tables and figures shall not be considered as requirements of the standard.

Last previous edition approved in as D — Olson Instruments sells the base model SE-1 system that exclusively uses the Sonic Echo methodology without the Impulse Response analysis. The method works best on solid concrete sections, and has limited application to unfilled steel pipe piles, H piles, or steel sheet piles. This standard does not purport to r5882-07 all of the safety concerns, if any, associated with its use. Training may be available at your location by one of our agents upon special arrangement.

This method works best for columnar type foundations such as piles and drilled shafts, but has d5882-0 been used successfully on mat foundations, abutment walls, and similar structures. These data assist evaluation of asrm 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.

Accelerometers shall be linear to at least 50 g. 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.

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

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. Astj — 07 Standard Test Method for Low Strain Impact Integrity Testing of Deep Foundations1 This adtm 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.

Alternatively, velocity or displacement transducers may be used to obtain velocity data, provided they are equivalent in performance to the specified accelerometers. Reliable results depend on many factors; Practice D provides a means of evaluating some of those satm.

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. Originally approved in 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.

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 measurement are included in this standard. All of Olson Instruments have been researched, tested, and used on-site d55882-07 by our sister company, Olson Engineeringworld reknowned for NDT consulting. The time domain record is then evaluated for pile integrity.

A hammer with a very hard plastic tip can induce a short input force pulse without causing local pile damage. These notes and footnotes excluding those in tables and figures shall not be considered as requirements of the standard. The impact should be applied axially to the pile normally on the pile head. The accelerometer s should f5882-07 placed at or near the pile head and shall have dd5882-07 sensitive axis parallel with the pile axis.

Users of this test method are cautioned that compliance with Practice D does not in itself assure reliable results. F5882-07 Olson Instruments when adding on to an existing system, or purchasing multiple systems as some of the components are common to other test methods.

This test method is applicable to long structural elements that function in a manner similar to any deep foundation units f5882-07 as driven piles, augeured piles, or drilled shaftsregardless of their method of installation provided that they are receptive to low strain impact testing.

This system, along with its associated software, uses only the time domain information in the data for the interpretation of reflections.
