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.
NOTE: A standard moisture block constructed in accordance with this Standard may be used as-
(a) a standard moisture block for use in the calibration of nuclear surface moisture-density gauges in accordance with AS 1289.5.8.4, if the water content has been assigned in accordance with this Standard;
(b) a primary standard moisture block for use in AS 1289.5.8.9 if the water content has been assigned in accordance with this Standard; or as
(c) a standard moisture block for which the moisture content may be assigned by comparison against primary standard moisture blocks in accordance with AS 1289.5.8.9.
