12-01-2013
Foreword
1 Scope
2 Normative references
3 Definitions and symbols
4 Principle
5 Apparatus
6 Consideration before sample reduction
7 Sample reduction technique using a rotary sample
divider
8 Sample reduction using a riffle box
9 Sample reduction using fractional shovelling
10 Sample reduction by quartering
11 Sample reduction to a test portion of a specified
mass within a small tolerance
12 Sample reduction with crushing to reduce the particle
size
13 Procedures for obtaining duplicate test portions
Annex A (informative) Half, three-quarters and five-eigths
divisions by a riffle box
Annex B (informative) Worked examples
Defines procedures for reduction of laboratory samples of aggregates for testing portions, where the test portion mass is either defined by a lower limit on the mass or a tolerance around a target mass, or determined exactly by test method requirements.
