    1. Scope

    1.1 These test methods cover procedures for the chemical analysis of metallic zinc powder in the form commercially known as zinc dust for use as a pigment in paints.

    1.2 The analytical procedures appear in the following order:

    Moisture and Other Volatile Matter7
    Coarse Particles8
    Matter Soluble in Hexane9 and 10
    Total Zinc11 and 12
    Metallic Zinc13 and 14
    Zinc Oxide15
    Calcium16 and 17
    Chlorine21 and 22
    Sulfur23 and 24
