ASTM D 5753 : 2018

1.1.1This guide covers the documentation and general procedures necessary to plan and conduct a geophysical borehole logging program as commonly applied to geologic, engineering, groundwater, and environmental (hereafter referred to as geotechnical) site characterizations.

1.1.2This guide applies to commonly used logging methods (see Tables 1 and 2) for geotechnical site characterizations.

1.1.3This guide provides an overview of the following:

1.1.4Logging procedures must be adapted to meet the needs of a wide range of applications and stated in general terms so that flexibility or innovation are not suppressed.

1.1.5To obtain detailed information on operating methods, publications (for example, 1, 2, 3, 4, 5, 6, 7, 8, and 9)2 should be consulted. A limited amount of tutorial information is provided, but other publications listed herein, including a glossar y of terms and general texts on the subject, should be consulted for more complete background information.

1.2.1This guide is not meant to describe the specific or standard procedures for running each type of geophysical log, and is limited to measurements in a single borehole.

1.2.2Surface or shallow-depth nuclear gages for measuring water content or soil density (that is, those typically thought of as construction quality assurance devices), measurements while drilling (MWD), cone penetrometer tests, and logging for petroleum or minerals are excluded.

1.2.3This guide offers an organized collection of information or a series of options and does not recommend a specific course of action. This document cannot replace education or experience and should be used in conjunction with professional judgment. Not all aspects of this guide may be applicable in all circumstances. This ASTM standard is not intended to represent or replace the standard of care by which the adequacy of a given professional service must be judged, nor should this document be applied without consideration of a project's many unique aspects. The word “Standard” in the title of this document means only that the document has been approved through the ASTM consensus process.

1.3.1If the method is used at sites with hazardous materials, operations, or equipment, it is the responsibility of the user of this guide to establish appropriate safety and health practices, and to determine the applicability of regulations prior to use.
