- Scope
- This International Standard specifies the methods to be employed for determination of size distributions by sieving of iron ore, utilizing sieves having aperture sizes of 36 μm or larger. The size distribution is to be expressed in terms of mass and percentage mass, passed or retained on selected sieves. The purpose of this International Standard is to provide a basis for any testing of iron ore involving size determination and for use by contracting parties in the sale and purchase of this material. When this International Standard is used for comparative purposes, agreement should be reached between the concerned parties on selection of the detailed method to be employed in order to eliminate sources of subsequent controversy.
