Several Members have requested D-7430 Part D: Section 30.3.1 on Preparation of Bias Test Samples be modified.

Not all coals exhibit this condition therefore the additional air drying of bulk samples is not necessary. The following is being suggested for those that do.
Keywordsauger sampling; barge sampling; coal; coal sampling; inspection; mechanical sampling; railroad car sampling; sample division; sample reduction; sampling systems; split-spoon sampling; statistical analysis; stock pile sampling; truck sampling; Mechanical sampling systems; Sampling; Coal/coke products; Coal products;
Ballot Item Approved as D7430-2016A and Pending Publication
