ASTM D5882-07 (Low Strain Impact Integrity Testing)
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 atsm shaftsregardless of their method of installation provided that they are receptive to low strain impact testing.
This standard may involve hazardous materials, operations, and equipment. Reliable aatm depend on many factors; Practice D provides a means of evaluating some of those factors. Sorry, this content is unavailable because your browser does not support iframes.
Users of this test method are cautioned that compliance with Practice D does not in itself assure reliable results. Alternatively, the hammer may have an.
This system, along with its associated software, uses only the time domain information in the data for the interpretation of reflections. A number in parentheses indicates the year of last reapproval.
The hammer may have a force load cell between the tip and hammer body. All of Olson Instruments have been researched, tested, and used on-site daily by our sister company, Olson Engineeringworld reknowned for D5882-7 consulting.
A hammer with a very hard plastic tip can induce a short input force pulse without causing local pile damage.
ASTM D 5882-16 Compliance Statement
The data are evaluated usually in the frequency domain. These notes and footnotes excluding those in tables and figures shall not be considered as requirements of asttm standard.
The OE Website is loaded with Tech Brief and project photos using the equipment shown on this website. This standard does not purport to address all of the safety concerns, if any, associated with its use. This system and its associated methodology can be used on both new and existing foundations and is performed by impacting the foundation and recording d882-07 from a defect or the foundation bottom with a nearby receiver s. Accelerometers shall be linear to at least 50 g.
This test method will not give information regarding the pile bearing capacity. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Enviado por Vitor flag Denunciar. 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 Sonic Echo-Impulse Response system is designed to determine the length and integrity of foundations asrm the top or part of the upper side atsm the foundation is accessible.
Sonic Echo-Impulse Response is used for low strain integrity testing of piles and determination of deep foundation length. 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.
These notes and footnotes excluding those in tables and figures shall not be considered as d588-207 of the standard. 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.
ASTM D – 07 Standard Test Method for Low Strain Impact Integrity Testing of Deep Foundations
Olson Instruments sells the base model SE-1 system that exclusively uses the Sonic Echo methodology without the Impulse Response analysis. Training may be available at your location by one of our agents upon special arrangement. How one applies the results obtained using this standard is beyond its scope. Alternatively, velocity or displacement transducers may be used to obtain velocity data, provided they are equivalent in performance to the specified accelerometers.
The method works best on solid concrete sections, and has limited application to unfilled steel pipe piles, H piles, or steel sheet piles. How one applies the results obtained using this standard is beyond its scope. The accelerometer s e5882-07 be placed at or near the pile head and shall have their sensitive axis parallel with the pile axis.
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.

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. Users of this test method are cautioned that compliance with Practice D does not in itself assure reliable results. 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 d55882-07 the designation indicates the year of original adoption or, in the case of revision, the year of last revision.
