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.
