[Pending Revision]Methods of testing soils for engineering purposes, Method 5.8.4: Soil compaction and density tests — Nuclear surface moisture-density gauges — Calibration using standard blocks
This Standard sets out the method for the calibration of the density system of a nuclear surface moisture-density gauge using standard density blocks and the calibration equation, so derived, defines the relationship between the density count ratio and field density for direct transmission measurement.
