ASTM D6169/D6169M-13 PDF Download

The ASTM D6169/D6169M-13 standard is titled "Standard Guide for Selection of Soil and Rock Sampling Devices Used With Drill Rigs for Environmental Investigations." This guide provides information on the major types of soil and rock sampling devices used on drill rigs to assist in selecting devices that are appropriate for the geological conditions of a site and to obtain samples that meet the objectives of the project. It emphasizes the importance of direct observation and collection of subsurface samples for site characterization in environmental investigations. However, it also stresses the need to consult with experienced professionals in sampling soil or rock before finalizing the method and type of sampling.

The standard recommends using this guide in conjunction with other related ASTM guides, such as Guides D2113 and D6151, as well as drilling method-specific guides. This is to ensure a comprehensive site investigation and sampling plan for sites that require the use of drill rigs for subsurface investigations. The selection of drilling methods and sampling devices are interconnected, and soil sample requirements may influence the choice of drilling method or vice versa.

The guide also suggests using other ASTM practices, such as Practice D5911 for data elements to identify a soil sampling site, Practice D4220 for preserving and transporting soil samples, Practice D5070 for preserving and transporting rock core samples, Practice D3694 for preparation of sample containers and preservation of organic constituents, and Practice D5088 for decontamination of field equipment used at waste sites.

It is important to note that the quality of the results produced by this standard depends on the competence of the personnel performing it and the suitability of the equipment and facilities used. Compliance with the relevant ASTM practices does not guarantee reliable results as many factors come into play. Professional judgment and experience should be used in conjunction with this standard for optimal results.
