GB/T 33303-2016
ActiveGuide for evaluation of measurement uncertainty in coal analysis
煤质分析中测量不确定度评定指南
Application Summary AI generated
This standard provides a framework for evaluating and expressing measurement uncertainty specifically in coal analysis, covering procedures such as proximate analysis, calorific value determination, and elemental composition testing. It is applied by coal testing laboratories, power plants, and mining enterprises in China to ensure the reliability and comparability of analytical results for quality control, trade settlement, and regulatory compliance. The guide aligns with general metrology principles but is tailored to the unique variability and sample preparation challenges inherent in coal.
