Specifies essential requirements for micaceous iron oxide when used as a pigment and/or as a weather resisting agent when incorporated in paints and related materials. The Standard is fully comprehensive as it includes photomicrographs depicting the acceptable structure, shape, size and colour of MIO particles, and contains all methods of test required for checking the specified properties.

This standard specifies requirements for micaceous iron oxide pigment (MIO) used primarily in paints for imparting corrosion resistance and long term durability to steel.
