These data assist evaluation d5882-007 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. The data are evaluated usually in the frequency domain. Sonic Echo-Impulse Response is used for low strain integrity testing of piles and determination of deep foundation length.

This standard may involve asttm materials, operations, and equipment. If damage is suspected during use, recalibrate or replace the accelerometer. This standard does not purport to address all of the safety concerns, if any, associated with its use. Users of this test method are cautioned that compliance with Practice D does not in itself assure reliable results. 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.

How one applies the results obtained using this standard is beyond its scope.

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

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. Originally approved in It is the responsibility of the user d5882-70 this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

A number in parentheses indicates the year of last reapproval. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. 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.

Click here for Agents. Olson offers Sonic Echo systems for use with three different platforms as shown in the chart below. 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. 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.

Current edition approved May 1, The OE Website is loaded with Tech Brief and project photos using the 5d882-07 shown on this website. Training may be available at your location by one of our agents upon special arrangement. Alternatively, velocity or displacement transducers may be used to obtain velocity data, provided they are equivalent in performance to the specified accelerometers.

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

The impact should be applied axially to the pile normally on the pile head. Link to Active This link will always route to the current Active version of the standard. No other units of measurement are included in this standard.

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

Last previous edition approved in as D — No asstm units of measurement are included in this standard. Reliable results depend on many factors; Practice D provides a means of evaluating some of those factors.

The hammer may have a force load cell between the tip and hammer body. 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. A hammer with a very hard plastic tip can induce a short input force pulse without causing local pile damage. Significance and Use 4. Olson Instruments sells the base model SE-1 system that exclusively uses the Sonic Echo methodology without the Impulse Response analysis.

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.

The time domain record is then evaluated for pile integrity. The accelerometer s should be placed at or near the pile head and shall have their sensitive axis parallel with the pile axis. 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.

This standard does not purport to address all of the safety concerns, if any, associated with its use. Reliable results depend on many factors; Practice D provides a means of evaluating some of those factors. Active view current version of standard. These notes and footnotes excluding those in tables and figures shall not be considered as requirements 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. This test method will not give information regarding the pile bearing capacity. All of Olson Instruments have been researched, tested, and used on-site daily by our sister company, Olson Engineeringworld reknowned for NDT consulting. A superscript epsilon e indicates an editorial change since the last revision or reapproval. 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 method works best on solid concrete sections, and has limited application to unfilled steel pipe piles, H piles, or steel sheet piles.
