This Standard sets out the methods for; 1) The calibration of the density systems of a nuclear thin-layer density gauge, using standard blocks; 2) The calibration of the depth factor systems of a nuclear thin-layer density gauge, using standard blocks and plates.

This Standard sets out the methods for the following:(a) The calibration of the density systems of a nuclear thin-layer density gauge, using standard blocks. The density calibration equations, so derived, define the relationships between density count ratio and field density reading.(b) The calibration of the depth factor systems of a nuclear thin-layer density gauge, using standard blocks and plates. The depth factor calibration equations, so derived, define the relationships between the depth factors and the thickness of a surface (top) layer.NOTE: The gauge calculates the density of a surface layer of nominated thickness, using the densities measured at two different backscatter systems (system 1 and system 2) and the depth factors for the nominated thickness.An adjustment of the calibration equation is determined for each material tested from measurements of field density, as detailed in AS/NZS 2891.14.2.
