    Significance and Use

    3.1 These test methods compile procedures which can be used to check the composition of purity of metallic zinc powder. This information is useful to both the formulator and users.

    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:

     

    Sections

    Moisture and Other Volatile Matter

    7

    Coarse Particles

    8

    Matter Soluble in Hexane

    9 and 10

    Total Zinc

    11 and 12

    Metallic Zinc

    13 and 14

    Zinc Oxide

    15

    Calcium

    16 and 17

    Lead

    18

    Iron

    19

    Cadmium

    20

    Chlorine

    21 and 22

    Sulfur

    23 and 24


    1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

    1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
