1、Designation:D1452/D1452M16Standard Practice forSoil Exploration and Sampling by Auger Borings1This standard is issued under the fixed designation D1452/D1452M;the number immediately following the designation indicates theyear of original adoption or,in the case of revision,the year of last revision.
2、A number in parentheses indicates the year of lastreapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the U.S.Department of Defense.1.Scope*1.1 This practice covers equipment and procedures for t
3、heuse of earth augers in shallow depth geotechnical exploration.This practice does not apply to hollow-stem augers.Uses ofhollow-stem auger drilling methods for geotechnical explora-tion are addressed in Test Method D6151.Samples recoveredfrom this standard are considered as belonging to Group A orB
4、 in accordance with D4220.The samples are disturbed andcan generally be used for classification testing(D2487,D2488),determination of compaction characteristics(D698,D1557),or any other standard that requires bulk samples.Forobtaining intact samples use of thin-walled sample tubes(D1587)in conjuncti
