Järnmalm och direktreducerat järn - Bestämning av storleksfördelning med siktning (ISO 4701:2008, IDT)
SS-ISO 4701:2008/Cor 1:2010
This International Standard specifies the methods to be employed for determination of size distributions by sieving of iron ore and direct reduced iron (exclude briquetted iron), utilizing sieves having aperture sizes of 36 µm or larger. The size distribution is 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 and direct reduced iron involving size determination for use by contracting parties in the sale and purchase of these materials.
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.
