1.1 This test method is intended for the determination of zinc oxide and phosphorous acid content of the pigment commercially known as zinc hydroxy phosphite. The zinc content is determined by ethylenediaminetetraacetate (EDTA) titration and calculated as zinc oxide (ZnO), while the phosphorus content is determined colorimetrically and calculated as phosphorous acid (H3PO3).

1.2 The analytical procedures appear in the following order:

Sections

Zinc oxide

6 through 8

Phosphorous acid

9 through 14
