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.
