ASTM D7430-12a
Standard Practice for Mechanical Sampling of Coal

1.2 Part A???Mechanical Collection and Within-System Preparation of a Gross Sample of Coal from Moving Streams???Covers procedures for the mechanical collection of a sample under Classification I-B-1 and I-B-2 (Practice D2234/D2234M) and the within-system preparation (reduction and division) of gross samples utilizing various components of the mechanical sampling system.

1.3 Part B???Mechanical Auger Sampling??????Describes procedures for the collection of an increment, partial sample, or gross sample of material using mechanical augers. Reduction and division of the material by mechanical equipment at the auger is also covered. Further manual or mechanical reduction or division of the material elsewhere shal......
