- Scope
- 1.1 These test methods cover procedures for the chemical analysis of yellow, orange, red, and brown pigments containing iron and manganese. The test methods apply specifically to the following pigments: synthetic hydrated yellow iron oxide, yellow ocher, red and brown iron oxides, raw and burnt umber, raw and burnt sienna, and venetian red. 1.2 The analytical procedures appear in the following order: ASTM Method ReferDry Pigments Sections ences Moisture and Other Volatile Matter 6 D280 Loss on Ignition 7 Coarse Particles 8 D185 Matter Soluble in Water 9 D1208 Organic Coloring Matter 10 Iron Oxide 11 and 12 Calcium Compounds (Reported as CaO) 13 and 14 Sulfates Soluble in Hydrochloric Acid 15 and 16 Lead Chromate (in Ochers) 17 Calcium Carbonate (in Venetian Red) 18 C25 Manganese (in Siennas and Umbers) 19 and 20 Pigment Pastes in Oil Pigment Content 21 D1208 Moisture and Other Volatile Matter 22 D1208 Nonvolatile Matter in Vehicle 23 Moisture by Distillation 24 D1208 Coarse Particles and Skins 25 D185 Consistency (Stormer) 26 D562 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, health, and environmental practices and determine the applicability of regulatory limitations prior to us. 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.
