ICS Code (Pigments and extenders): 87.060.10
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.

1.3 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.
