1、Designation:D606710Standard Practice forUsing the Electronic Piezocone Penetrometer Tests forEnvironmental Site Characterization1This standard is issued under the fixed designation D6067;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revisio
2、n,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope*1.1 The electronic cone penetrometer test often is used todetermine subsurface stratigraphy for geotechnical and
3、 envi-ronmental site characterization purposes(1).2The geotechnicalapplication of the electronic cone penetrometer test is dis-cussed in detail in Test Method D5778,however,the use of theelectronic cone penetrometer test in environmental site char-acterization applications involves further considera
4、tions thatare not discussed.For environmental site characterization,it ishighly recommended to use the Piezocone(PCPT or CPTu)option in Test Method D5778 so information on hydraulicconductivity and aquifer hydrostatic pressures can be evalu-ated.1.2 The purpose of this practice is to discuss aspects
5、 of theelectronic cone penetrometer test that need to be consideredwhen performing tests for environmental site characterizationpurposes.1.3 The electronic cone penetrometer test for environmentalsite characterization projects often requires steam cleaning thepush rods and grouting the hole.There ar
6、e numerous ways ofcleaning and grouting depending on the scope of the project,local regulations,and corporate preferences.It is beyond thescope of this practice to discuss all of these methods in detail.A detailed explanation of grouting procedures is discussed inGuide D6001.1.4 The electronic cone
7、penetrometer may be be combinedwith other direct push sampling and testing methods.Estimatedsoil types can be confirmed by soil sampling(Guide D6282).Cone penetrometer tests are often used to locate aquifers forinstallation of wells(Practice D5092,Guide D6274).Conepenetrometers can be equipped with
8、additional sensors forgroundwater quality evaluations(Practice D6187).Location ofother sensors must conform to requirements of Test MethodD5778.1.5 This practice is applicable only at sites where chemical(organic and inorganic)wastes are a concern and is notintended for use at radioactive or mixed(c
9、hemical and radio-active)waste sites.1.6 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.7 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user o
10、f this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.1.8 Standard PracticeThis practice offers a set of instruc-tions for performing one or more specific operations.Thisdocument cannot replace education or exper
11、ience and shouldbe used in conjunction with professional judgment.Not allaspects of this practice may be applicable in all circumstances.This ASTM standard is not intended to represent or replace thestandard of care by which the adequacy of a given professionalservice must be judged,nor should this
