ISO 11459:1997

Overview

ISO 11459:1997 specifies the procedures for the preparation and certification of certified reference materials (CRMs) for iron ores. These materials are essential for ensuring the accuracy and reliability of chemical analysis in various applications, including mining, metallurgy, and environmental monitoring. The standard outlines the necessary steps to produce CRMs that meet stringent quality criteria, thereby supporting laboratories in achieving compliance with international testing standards.

Key Requirements

• Material Selection: The standard provides guidelines for selecting iron ore samples that are representative of the material being analysed.
• Preparation Procedures: Detailed methodologies for sample preparation are outlined, ensuring homogeneity and stability of the reference materials.
• Certification Process: The standard describes the certification process, including the determination of chemical composition and the establishment of traceability to national or international standards.
• Documentation: Comprehensive documentation is required to support the certification, including analytical results, methods used, and any uncertainties associated with the measurements.

Implementation Benefits

Adopting ISO 11459:1997 provides several practical benefits for laboratories involved in the analysis of iron ores:

• Enhanced Accuracy: By using certified reference materials, laboratories can improve the accuracy of their chemical analyses, leading to more reliable results.
• Quality Assurance: The standard supports quality assurance processes, helping laboratories to demonstrate compliance with regulatory requirements and industry standards.
• Reputation and Trust: Laboratories that utilise ISO-compliant CRMs can enhance their reputation among clients and stakeholders by demonstrating a commitment to quality and accuracy.
• Cost Efficiency: Improved accuracy reduces the likelihood of costly errors in analysis, thus saving time and resources in the long run.

Compliance Value

Compliance with ISO 11459:1997 is crucial for laboratories that perform chemical analyses of iron ores. The standard ensures that:

• Regulatory Compliance: Laboratories can meet the requirements set forth by regulatory bodies, ensuring that their analyses are accepted in legal and commercial contexts.
• International Recognition: Adhering to an internationally recognised standard facilitates global trade and collaboration, as results from compliant laboratories are more readily accepted worldwide.
• Continuous Improvement: The standard encourages ongoing evaluation and improvement of analytical processes, fostering a culture of quality within the laboratory.

In conclusion, ISO 11459:1997 serves as a vital framework for the preparation and certification of reference materials for iron ores. By implementing the guidelines set forth in this standard, laboratories can enhance their analytical capabilities, ensure compliance with regulatory requirements, and maintain a competitive edge in the industry.
