AS 1141.3.1:2021 pdf download.Methods for sampling and testing aggregates Method 3.1: Sampling - Aggregates.

6.1 General

Ideally, sample increments should be taken while aggregate is in motion either at a discharge or transfer point or from a moving

conveyor, but this practice is dangerous if carried out manually. Sample increments from stopped conveyor belts provide the best

alternative to sampling from material in motion. Belt samples are a case where a single sample increment forms the entire sample.

The ability to treat a single belt sample of this type as representative of the lot is acceptable when the production process is

stable, an entire and full depth sample is taken, and the sample size conforms with the requirements of Table 2.

It is more difficult to obtain fully representative samples from material at rest in stockpiles or trucks. However, adequate

samples should he obtained from aggregate in these situations if the instructions of the relevant clauses of this document are

conformed to.
