GB/T 22279-2008
ActiveGuide for development of certified reference materials for the composition analysis and the physical property measurements of coal
煤炭成分分析和物理特性测量标准物质研制导则
Application Summary AI generated
This standard provides guidelines for the development and certification of reference materials used to calibrate instruments and validate methods for analyzing coal composition (e.g., ash, sulfur, carbon) and measuring its physical properties (e.g., calorific value, moisture). It is applied in coal testing laboratories, mining operations, and quality control settings to ensure accuracy and traceability in coal classification, trading, and utilization. The guide supports the production of reliable reference materials essential for compliance with national and international coal specifications.
