Overview
SIST ISO 15239:2006 - "Solid mineral fuels -- Evaluation of the measurement performance of on-line analysers" is an international standard developed by SIST (Slovenian Institute for Standardization) in accordance with ISO guidelines. This standard is designed to outline procedures and provide guidance for evaluating the measurement performance of on-line analysers used with solid mineral fuels, such as coal, lignite, and coke. As on-line analyser technology becomes increasingly integral to quality control, process optimization, and compliance in the solid fuel industry, this standard plays a crucial role in ensuring measurement reliability and consistency.
Key Topics
SIST ISO 15239:2006 covers several core topics relevant to laboratories, manufacturers, and operators working with solid mineral fuels and real-time analytical systems:
- Types of On-line Analysers: Presents an overview of currently available analyser types, including those based on absorption, scattering, excitation processes, measurement of natural radiation emission, and property changes.
- Evaluation Procedures: Describes detailed procedures for assessing various aspects of measurement performance, such as instrument stability, calibration, and operational precision.
- Statistical Assessment Methods: Outlines statistical techniques for analysing test data, enabling objective assessment and comparison of analyser performance.
- Operational Considerations: Details the importance of testing under both static and dynamic conditions to simulate real operational scenarios.
- Definitions and Terminology: Clarifies key concepts including accuracy, precision, bias, calibration, and repeatability, ensuring a common understanding for implementation and reporting.
Applications
This standard has broad and practical applications across the coal and solid mineral fuel industries:
- Quality Control: Ensures on-line analysers provide reliable, real-time data for assessing fuel quality during mining, processing, and handling operations.
- Compliance and Reporting: Supports regulatory compliance by standardizing how analyser performance is verified and documented.
- Process Optimization: Provides the technical foundation to evaluate and thereby improve the accuracy of analyser systems, leading to better control of fuel properties such as ash content, moisture, and calorific value.
- Facility Audits and Inspections: Assists operators and auditors in assessing analyser performance as part of regular facility checks or certification processes.
- Equipment Commissioning: Guides manufacturers and end-users through best practices for verifying and documenting analyser performance prior to operational deployment.
