Scope

This Standard sets out the method for the calibration of the density system of a nuclear surface moisture-density gauge, using standard blocks, when operated in the backscatter mode. The calibration equation, so derived, defines the relationship between the density count ratio and field density. An adjustment to the calibration equation is determined for each material tested from measurements of field density tested in accordance with AS/NZS 2891.14.1.2.
