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: Sections Moisture and Other Volatile Matter 7 Combined Water 8 Chromium: Dichromate Method 9 – 11 Thiosulfate Method 9 , 12 , and 13 Zinc: Hydroxyquinoline Method 9 , 14 , and 15 Ferrocyanide Method 9 , 16 , and 17 Alkaline Salts 18 and 19 Sulfates 20 and 21 Chlorides 22 and 23 Matter Insoluble in Dilute Acetic Acid 24 Coarse Particles 25 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. ====== 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.
