Twenty years ago D24 established reference materials for the D1619 test method. These were designated simply as Standard A, Standard B, Standard C, and Standard D. These materials are sold as a set. One of the materials is now depleted. New reference materials will be introduced in the next few months. These materials should be classified within D7849. This ballot is to add them to D7849.
