| description | One of the important elements for addressing the requirements of international Standard ISO/IEC 17025:2006, specifically set forth in paragraph 5.4.6.2, is to assess the uncertainty of testing and/or calibration. For determination the coal technical analysis uncertainty (moisture, ash, volatiles and combustible substances, c-fix, total sulfur, gross calorific value and net calorific value), the certified reference materials (CRM) benzoic acid (Ref.: 33 045 and Ref.: C723, Id. No.: 32 430 00) and coal tags GBW 11107k were used. Potential laboratory reference material (RM) was also used for comparison the measurement results and uncertainty in order that, after sufficient number of measurements and statistical analysis, could be used as a laboratory RM. The results showed that both CRM and selected potential laboratory RM could be successfully applied to determine the uncertainty of technical coal analysis, what is significantly cheaper for laboratory work, and in accordance with Standard ISO 17025. |
