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.
Sorry, this content is unavailable because your browser does not support iframes. Active view current version of standard. A superscript epsilon e indicates an editorial change since the last revision or reapproval. No other units of measurement are included in this standard. This test method is applicable to long structural elements that function astmm a manner similar to any deep foundation units such as driven piles, augeured piles, or c5882-07 shaftsregardless of their method of installation provided that they are receptive to low strain impact testing.
Alternatively, velocity or displacement transducers may be used to obtain velocity data, provided they are equivalent in performance to the specified accelerometers.
Originally approved in The accelerometer s should be placed at or near the pile head and shall have their 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.
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. Significance and Use 4. 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 on the competence of the personnel performing it, and the suitability of the equipment and facilities used.
How one applies the results obtained using this standard is beyond its scope. Link to Active D5882–07 link will always route to the current Active version of the standard.
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. The impact should be applied axially to the pile normally on the pile head.
Alternatively, the hammer may have an. The method works best on solid concrete sections, and has limited application to unfilled steel pipe piles, H piles, or steel sheet piles. These notes and footnotes excluding those in tables and figures shall not be considered as requirements of the standard.
This system, along with its associated software, uses only the time domain information d5882-0 the data for the interpretation of reflections. Enviado por Vitor flag Denunciar. No other units of measurement are included in this standard. The OE Website is loaded with Tech Brief and project photos using the equipment shown on this website.
ASTM D 5882-16 Compliance Statement
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. Training may be available at your location by astj of our agents upon special arrangement.
These notes and footnotes excluding those in tables and figures shall not be considered as requirements of astn standard.
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. Last previous edition approved in as D — 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 data are evaluated usually in the frequency domain.
Olson Instruments sells the base model SE-1 system that exclusively uses the Sonic Echo methodology without the Impulse Response analysis. Accelerometers shall be linear to at least 50 g. The hammer may have a force load cell between the tip and hammer body. Users of this test method are cautioned that compliance xstm Practice D does not in itself assure reliable results.
ASTM D – 07 Standard Test Method for Low Strain Impact Integrity Testing of Deep Foundations
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. This standard d5882-007 involve hazardous materials, operations, and equipment. Current edition approved May 1, How one applies the results obtained using this standard is beyond its scope.
This test method will not give information regarding the pile bearing capacity. Reliable results depend on many factors; Practice D v5882-07 a means of evaluating some of those factors. Olson offers Sonic Echo systems for use with three different platforms as shown in the chart below.
