Terminology3.1 Definitions: Except as listed below, all definitions are inaccordance with Terminology D653.3.2 Definitions of Terms Specific to This Standard:3.2.1 field loga record prepared during subsurface explo-rations of soil and rock to document procedures used, test data,de
18、scriptions of materials and depths where encountered,ground water conditions, and other information.4. Summary of Guide4.1 This guide describes the type of information that shouldbe recorded during the execution of field subsurface explora-tions in soil and rock. The information described relates to
19、 theproject, personnel, methods of investigation and equipmentused, visual description of subsurface materials and groundwater conditions, in-situ testing, installation of monitoringequipment, and other data that may be appropriate.5. Significance and Use5.1 The preparation of field logs provides do

This guide may be used for a broad range ofinvestigations.5.2 The recorded information in a field log will depend onthe specific purpose of the sit
21、e investigation. All of theinformation given in this guide need not appear in all field logs.NOTE 1The quality of the result produced by this standard isdependent on the competence of the personnel performing it, and thesuitability of the equipment and facilities used. Agencies that meet thecriteria
22、 of Practice D3740 are generally considered capable of competentand objective sampling. Users of this practice are cautioned that compli-ance with Practice D3740 does not in itself assure reliable results. Reliableresults depend on many factors; Practice D3740 provides a means ofevaluating some of t
23、hose factors.6.
