Overview
ISO 11323:2010 - Iron ore and direct reduced iron - Vocabulary is an International Organization for Standardization (ISO) glossary that defines the technical terms used by ISO/TC 102 standards covering sampling, sample preparation, moisture and particle-size analysis, and physical testing of iron ore and direct reduced iron (DRI). The third edition (2010) consolidates consistent definitions for natural and processed iron ores, agglomerates (sinter, pellets), DRI products (including HBI/CBI), sampling terminology, particle-size and moisture concepts, physical and chemical test terms, and relevant statistical language.
Key Topics
- Core definitions for natural and processed iron ore (e.g., lump, fine, concentrates, sinter, pellets) and direct reduced iron (DRI) plus briquettes (HBI, CBI).
- Sampling vocabulary: lot, strata, increment, gross/partial/test samples, sampling regime/scheme/procedure, manual vs mechanical sampling, mass-basis/time-basis/stratified/systematic sampling.
- Sample preparation and division: sample preparation, sample division (proportional/constant mass), minimum mass requirements, reserve and test samples.
- Particle-size analysis and moisture: particle, particle size (sieving-based definitions), specification size, and links to test sieves (ISO 565, ISO 3310 series).
- Physical and chemical testing terms and statistical concepts: precision, repeatability, quality variation, Grubbs’ test (outlier detection), with informative annexes on statistical terms and multilingual equivalent terms.
- Normative references cited in the standard for test sieves and statistical methods (e.g., ISO 565; ISO 3310-1/-2; ISO 3086; ISO 5725-2).
Applications and Users
ISO 11323:2010 is intended to ensure consistent terminology across the iron ore and DRI supply chain. Typical users include:
- Mining and mineral processing engineers creating technical specifications and reports
- Quality assurance/quality control (QA/QC) labs performing sampling, moisture and particle-size analyses
- Steelmakers and pelletizing plants specifying feedstock and product quality
- Traders, logistics and contract managers writing procurement and sale contracts
- Standards writers, auditors and regulators who require harmonized definitions for compliance and dispute resolution
Related Standards
ISO 11323:2010 is an essential reference for anyone involved in iron ore and DRI testing, sampling protocols, and specification drafting who needs clear, internationally harmonized vocabulary.
