Significance and Use
4.1 The fines content of silica is related to the bulk flowability, dustiness, and in some instances, the level of dispersion. Due to the many other variables that influence dispersion and handling, the significance of fines content must be determined by the user.
4.2 A similar test method is known for carbon black, see Test Method D1508.
