This European Standard specifies methods for obtaining samples of aggregates from deliveries, preparation and processing plants including stocks. The aim of sampling is to obtain a bulk sample that is representative of the average properties of the batch. The methods specified in this standard are also suitable for obtaining sampling increments which may be tested separately. The methods specified in this European Standard are based on manual procedures. Mechanical or automatic sampling and sample reduction may also be used. Criteria for the design and the assessment of such equipment are given in an annex of this standard. The methods specified in this European Standard are limited to civil engineering purposes.
