    Significance and Use

    3.1 This test method has been developed to standardize the chemical analysis of zinc chromate yellow pigment and to provide alternate methods of analysis for chromium and zinc.

    1. Scope

    1.1 These test methods cover procedures for the chemical analysis of the pigment known commercially as “zinc yellow” or “zinc chromate yellow.”

    1.2 The analytical procedures appear in the following order:



    Moisture and Other Volatile Matter


    Combined Water




     Dichromate Method

    9 – 11

     Thiosulfate Method

    9, 12, and 13



     Hydroxyquinoline Method

    9, 14, and 15

     Ferrocyanide Method

    9, 16, and 17

    Alkaline Salts

    18 and 19


    20 and 21


    22 and 23

    Matter Insoluble in Dilute Acetic


    Coarse Particles


    1.3 The values stated in SI units are to be considered the standard. The values given in parentheses are for information only.

    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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

    1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
