SUPERSEDED (see Active link, below)
ASTM D444
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:
Sections Moisture and Other Volatile Matter 7 Combined Water 8 Chromium: Dichromate Method 9 to 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 24 Acid Coarse Particles 251.3 This standard does not purport to address all of the safety problems, 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.>
