Significance and Use
4.1 This guide provides guidance as to the appropriate/typical mineralogy observed when iron and steel slag is produced during a variety of processes in the manufacture of iron and steel.
4.2 Slag can be considered a product based on the mineralogy of samples that are tested using X-ray diffraction, phase recognition and characterization, powdered XRD-Rietveld analysis, and SEM-PARC results, using this guide.
1.1 This standard is intended to provide guidance as to the appropriate/typical mineralogy observed when iron and steel slag, produced during the manufacture of iron and steel, is designated as a product. The included information covers the mineral properties of blast furnace slag and steel slag when they are manufactured in conjunction with the production of iron or steel, or both ( ).
Note 1: This guide is not intended to be used to determine the applicability of iron or steel slag, or both, for various applications. Terminology designates steel slag as a product, while Terminology designates blast furnace slag as a product. Its sole intent is to provide guidance as to the typical mineralogy when the iron or steel slag, or both, is designated as a product.
1.2 The values stated in SI units are to be regarded as standard. No other units are utilized in this standard.
1.3 The text of this standard references notes and footnotes that provide explanatory material. These notes and footnotes (excluding those in tables and figures) should not be considered as requirements of the specification.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.5 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.
