[Current]Methods of testing soils for engineering purposes, Method 5.8.7: Soil compaction and density tests — Nuclear surface moisture-density gauges — Water content of a standard moisture block using hydrogen content of components
This Standard sets out the method for the construction of and assignment of water content using the hydrogen content of the components, to a standard moisture block for use in the calibration of nuclear surface moisture-density gauges in accordance with AS 1289.5.8.4. The block shall consist of an intimate mix of sand and polystyrene at a specific proportion. Guidance on the number of blocks required for a set of standard moisture blocks and the proportioning of the sand and polystyrene mixes is given in AS 1289.5.8.4.
