Full title and description

SA TR 2.35:2014 — Certified reference materials, Part 35: Iron ore — Preparation and certification of ASCRM‑035 (Yilgarn Hematite). This Technical Report documents the preparation, characterisation and certification procedures for the certified reference material ASCRM‑035 (Yilgarn Hematite), produced to support composition and analytical testing of iron ore materials.

Abstract

This Technical Report gives background, laboratory procedures, sampling and certification methodology used to prepare ASCRM‑035 (Yilgarn Hematite) as a certified reference material for iron‑ore analysis. It describes sample selection, homogenisation, stability assessment, interlaboratory characterisation studies and assignment of certified values and associated uncertainties for key analytes relevant to iron‑ore testing.

Scope

The report covers the processes and technical data required to prepare and certify the reference material ASCRM‑035 (Yilgarn Hematite). Scope includes sampling and sample preparation methods, homogeneity and stability testing, analytical characterisation (including interlaboratory study design), calculation and assignment of certified values and uncertainty statements, plus accompanying documentation required for distribution and use of the CRM in iron‑ore chemical analysis.

Key topics and requirements

• Definition and intended use of ASCRM‑035 as a certified reference material for iron‑ore analyses.
• Sampling protocol and sample preparation/homogenisation procedures required to produce a representative CRM batch.
• Analytical characterisation methodology: selection of analytes, participating laboratories, measurement protocols and statistical treatment of results.
• Assessment of homogeneity and stability; criteria for acceptance.
• Assignment of certified values with uncertainty estimates and instructions for users on certificate interpretation and traceability.
• Packaging, labelling and distribution considerations for a mineral CRM.

Typical use and users

Used by analytical laboratories, assay houses, mining and processing companies, instrument manufacturers and accreditation bodies for method validation, quality control and proficiency testing in iron‑ore chemical analysis. Laboratories use ASCRM‑035 to verify analytical performance for key elements and parameters in hematite ore matrices.

Related standards

Usually referenced alongside Standards Australia and international guidance on certified reference materials, e.g. ISO/REM related CRM guidance and other SA TR parts or ASCRM product documentation (ASCRM‑035). It is also used in conjunction with laboratory quality standards and accreditation requirements for chemical testing.
