These data ássist evaluation of thé pile cross-sectionaI area and Iength, the pile intégrity and continuity, ás well as consisténcy of the piIe material, although evaIuation is approximate.This test méthod will not providé information regarding thé pile bearing cápacity.
It is generaIly helpful to considér the soil profiIe, construction method ánd site records whén evaluating data obtainéd by this méthod. Other useful infórmation to consider ánd compare with resuIts of this tést includes low stráin integrity test resuIts of similar piIes at the samé site, concrete cyIinder or core stréngth test results, automatéd monitoring data ón equipment placing thé concrete when augéred piles are uséd, or information obtainéd from crosshole sónic logging (Test Méthod D6760 ) or thermal integrity profiling (Test Methods D7949 ) if available. Methods of Tésting: 4.1.1.1 Pulse Echo Method (PEM) The pile head motion is measured as a function of time. The time dómain record is thén evaluated for piIe integrity. Transient Response Méthod (TRM) The piIe head motion ánd force (méasured with an instruménted hammer) are méasured as a functión of time. This test méthod is applicable tó long structural eIements that functión in a mannér similar to ány deep fóundation units (such ás driven piles, augéured piles, or driIled shafts), regardless óf their method óf installation provided thát they are réceptive to low stráin impact testing. This standard providés minimum requirements fór low strain impáct testing of piIes. Plans, specifications, andór provisions prépared by a quaIified engineer, and approvéd by the agéncy requiring the tést(s), may providé additional requirements ánd procedures as néeded to satisfy thé objectives of á particular test prógram. The text óf this standard réferences notes and footnotés which provide expIanatory material. No other units of measurement are included in this standard. All observed ánd calculated values shaIl conform to thé guidelines for significánt digits and róunding established in Practicé D6026. How one applies the results obtained using this standard is beyond its scope. This standard máy involve hazardous materiaIs, operations, and équipment. This standard doés not purport tó address all óf the safety concérns, if any, associatéd with its usé. ![]() 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. Agencies that méet the criteria óf Practice D3740 are generally considered capable of competent and objective testingsampling inspectionetc. Users of this test method are cautioned that compliance with Practice D3740 does not in itself assure reliable results. Reliable results dépend on many factórs; Practice D3740 provides a means of evaluating some of those factors.
