ASTM D50-90(1999)
Historical Standard: ASTM D50-90(1999) Standard Test Methods for Chemical Analysis of Yellow, Orange, Red, and Brown Pigments Containing Iron and Manganese
SUPERSEDED (see Active link, below)
ASTM D50
1. 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 Refer- Dry Pigments Sections ences Moisture and Other Volatile Matter 6 D 280 Loss on Ignition 7 Coarse Particles 8 D 185 Matter Soluble in Water 9 D 1208 Organic Coloring Matter 10 Iron Oxide 11 and 12 Calcium Compounds (Reported as CaO) 13 and 14 Sulfate Soluble in Hydrochloric Acid 15 and 16 Lead Chromate (in Ochers) 17 Calcium Carbonate (in Venetian Red) 18 C 25 Manganese (in Siennas and Umbers) 19 and 20 Pigment Pastes in Oil Pigment Content 21 D 1208 Moisture and Other Volatile Matter 22 D 1208 Nonvolatile Matter in Vehicle 23 Moisture by Distillation 24 D 1208 Coarse Particles and Skins 25 D 185 Consistency (Stormer) 26 D 5621.3 This standard does not purport to address the safety problems 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. >
