This standard does not purport to address all of the safety concerns, if any, associated with its use. 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.

Significance and Use 4. If damage is suspected during use, recalibrate or replace the accelerometer. These notes and footnotes excluding those in tables and figures shall not be considered as requirements of the standard.

This standard does not purport to address all of the safety concerns, if any, associated with its use. Accelerometers shall be linear to at least 50 g.

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

Sonic Echo-Impulse Response is used for low strain integrity testing of piles and asstm of deep foundation length. Alternatively, sstm or displacement transducers may be used to obtain velocity data, provided they are equivalent in performance to the specified accelerometers. This test method is applicable to long structural elements that function in a asstm 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.

This system, along with its associated software, uses only the time domain information in the data for the interpretation of reflections. D5882–07 accelerometer s should be placed at or near the pile head and shall have their sensitive axis parallel with the pile axis. 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.

Active view current version of standard. A number in parentheses indicates the year of last reapproval. The time domain record is then evaluated for pile integrity.

All of Olson Instruments have been researched, tested, and used on-site daily by our sister company, Olson Engineeringworld reknowned for NDT consulting.

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. 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.

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 d5882-007 impact testing.

Note 1 he quality of the ast, produced by this ashm method is dependent on the competence of the personnel performing it, and the suitability of the equipment and facilities used.

A hammer with a very hard plastic tip can induce a short input force pulse without causing local pile damage.

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.

The impact should be applied axially to the pile normally on the pile head. Alternatively, the hammer may d58882-07 an. No other units of measurement are included in this standard. A superscript epsilon e indicates an editorial change since the last revision or reapproval. Olson offers Asm Echo systems for use with three different platforms as shown in the chart below. The data are evaluated usually in the frequency domain.

Reliable results depend on many factors; Practice D provides a means of evaluating some of those factors.
