• CORE is used to transfer details of rotary coring in rock and soil materials.
• The data transferred for coring in rock will be more extensive than for soil coring; specifically the SCR and RQD are not determined for soil cores.
• CORE_DURN permits the inclusion of the time duration for the core run to be drilled if this is a specified additional measured parameter.
