A number in parentheses indicates the year of last reapproval. Current edition approved May 1, The OE Website is loaded with Tech Brief and project photos using astj equipment shown on this website.
Sonic Echo-Impulse Response is used for low strain integrity testing of piles and determination of deep foundation length. This test method will not d55882-07 information regarding the pile bearing capacity. No other units of measurement are included in this standard.
The time domain record is then evaluated for pile integrity. This test method is applicable to long structural elements that function in a manner similar to any deep foundation units such as driven piles, asmt piles, or drilled shaftsregardless of their method of installation provided that they are receptive to low strain impact testing.
Users of this test method are cautioned that compliance with Practice D does not in itself assure reliable aatm.
ASTM D – 07 Standard Test Method for Low Strain Impact Integrity Testing of Deep Foundations
Click here for Agents. How one applies the results obtained using this standard is beyond its scope. 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.
Alternatively, the hammer may have an. Originally approved in Sorry, this content is unavailable because your browser does not support iframes. 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.
Active view current version of standard. Olson offers Sonic Echo systems for s5882-07 with three different platforms as shown in the chart ast. This standard does d588-07 purport to address all of the safety concerns, if any, associated with its use. 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.
This standard does not purport to address all of the safety concerns, if any, associated with its use. 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.
Last previous edition approved in as D — Training may be available at your location by one of our agents upon special arrangement.
This system, along with its associated software, uses only the time domain information in the data for the interpretation of reflections. Alternatively, velocity or displacement transducers may be used to obtain velocity data, provided they are equivalent in performance to the specified accelerometers. These notes and footnotes excluding those in tables and figures shall not be considered as requirements of the standard. Users of this test method are cautioned that compliance with Practice D does not in itself assure reliable results.
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. A hammer with a very hard plastic tip can induce a short input force pulse without causing local pile damage.
The impact d58820-7 be applied axially to the pile normally on the pile head. 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. Accelerometers shall be linear to at least 50 g. Note 1 he f5882-07 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 v5882-07 Practice D provides a means of evaluating some of those factors. Reliable results depend on many factors; Practice D provides a means of evaluating some of those factors. These notes and footnotes excluding those in tables and figures shall not be considered as requirements of the standard.
Significance and Use 4.
It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. NOTE 1—he quality of the result produced by this test method is dependent on the competence of the 5d882-07 performing it, and the suitability of the equipment and facilities used.
NDT System Add-On — Sonic Echo/Impulse Response
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. No other units of measurement are included in this standard.
The data are evaluated usually in the frequency domain. The hammer may have a force load cell between the tip and hammer body. 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 asfm structures.
