ASTM D2113-14 PDF Download

ASTM D2113-14 is a standard practice that provides guidelines, requirements, and procedures for core drilling, coring, and sampling of rock for the purpose of site exploration. The standard emphasizes the importance of rock cores as samples of record, which provide information about the geological, physical, and engineering nature of the subsurface. It highlights the need to preserve the core samples using specific procedures for a specified period of time, depending on the nature and significance of the engineered structure.

The standard also emphasizes the importance of handling rock cores carefully to ensure that their properties are not altered due to mechanical damage or changes in ambient conditions. It applies to various types of core drilling, including vertical, horizontal, and angled boreholes, and is applicable to both hard and soft rock.

However, it is important to note that the standard does not address considerations for core drilling for geo-environmental site characterization and installation of water quality monitoring devices. These aspects are covered in separate ASTM guides.
