Historical Standard: ASTM D3724-82(1995)e1 Standard Specification for Synthetic Brown Iron Oxide Pigment
SUPERSEDED (see Active link, below)
ASTM D3724
1. Scope
1.1 This specification covers the pigments commercially known as synthetic pure brown iron oxides and blends. These pigments are suitable for use in paints and coatings. Methods of manufacture are:
1.1.1 Precipitation of iron salts.
1.1.2 Calcination of precipitated iron oxides.
1.1.3 Blends of synthetic red, yellow, and black iron oxides.
1.1.4 Blends of synthetic red, yellow, and black iron oxides plus the addition of carbon black to a maximum of 5.0 %. Small amounts of carbon black are added to obtain tinting colors not obtainable when synthetic brown iron oxide or carbon black are used singly.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
