Scope
This Standard sets out the method for the determination of the assigned water content of 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 a regular array of vertical aluminium plates separated by air gaps that can be filled with water. Guidance on the number of blocks required for a set of standard moisture blocks is given in AS 1289.5.8.4.
NOTE: A standard moisture block with water content assigned 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; or as
(b) a primary standard moisture block for use in AS 1289.5.8.9.
