[Superseded]Methods for sampling and testing aggregates, Method 3.1: Sampling — Aggregates
This Standard defines requirements and specifies methods for taking samples of aggregates and sands, for subdividing samples and for packing and forwarding samples for examination and testing. This Standard is limited to aggregate and rock products with a nominal size of 63 mm or less. The Standard may be applied to non-stabilized soil product or soil and rock blends, again provided that the maximum particle size is less than 75 mm. For rock, aggregate and soil products larger than these sizes AS 1141.3.2 applies.
