TS ISO 11323

TS ISO 11323 is a vocabulary standard that brings together the terms and definitions used for iron ore and direct reduced iron. It provides a common technical language for TC 102 standards dealing with sampling, sample preparation, moisture, particle size analysis, and physical testing, helping the same material and the same test result be understood consistently across different laboratories and organisations.

What the terminology covers in practice

Iron ore is a primary raw material in the ironmaking chain, while direct reduced iron is a reduced iron product associated with routes other than the conventional blast furnace route. In this field, sampling and sample preparation are critical because reliable conclusions must often be drawn from only a portion of the bulk material. Moisture and particle size distribution also have a direct influence on handling, processing behaviour, and the comparability of test results, so shared definitions are essential for technical consistency.

How this vocabulary standard supports the domain

• It standardises the meaning of terms used in TC 102 standards.
• It supports consistent language for iron ore and direct reduced iron.
• It clarifies conceptual distinctions between sampling, sample preparation, moisture, particle size distribution, and physical testing.
• It helps align measurement and reporting terminology between laboratories, producers, and purchasers.

This standard is primarily a terminology document rather than a test method standard. In other words, it does not itself set out a single experimental procedure or numerical acceptance limit; instead, it supports the correct and consistent use of technical terms across the related TC 102 standards.

This current TSE edition is based on ISO 11323:2010 and serves as a common reference for technical teams working with iron ore terminology.
