EVALUATION OF COMPONENTS UNCERTAINTY IN COMPOSITE MATERIAL WEAR RESISTANCE

Accurately estimating measurement uncertainty is crucial for reliable and meaningful results in material abrasive wear resistance testing. In general, the process of assessing uncertainty involves several steps, including identifying sources of uncertainty, determining correlations between input quantities, and calculating various types of uncertainties. Knowing the measurement uncertainty allows for: ensuring compliance with established standards, monitoring and improving the accuracy and reliability of the testing process. The components of the measurement uncertainty of abrasive wear resistance are studied in detail in the paper. It is revealed that indirect factors can have a predominant effect on the total uncertainty of the method.The methodology for assessing uncertainty should be described in regulatory documents to ensure consistency and comparability across different testing laboratories. By incorporating uncertainty assessment into abrasive wear resistance testing, researchers and engineers can improve the quality and reliability of their results, leading to better decision-making in materials selection and process optimization.
