Note: all ribbon sizes listed in the shaded areas of the tables are rolled from flats and are considered to have true rectan- gular cross-sections. Ribbons in the white areas, however, are rolled from wire and have round edges. Therefore, the values shown for these sizes have been calculated in accordance with ASTM recommendations.
