Abstract
Chemical analysis measurements provide a basis for important decisions concerning health, environmental protection, industrial processes, international trade, and commerce, among others. Therefore, chemical measurements must be good and have a known quality to be meaningful and to provide an adequate result for its intended purpose. Analysts could ask what “good” and “of known quality” means. This can be interpreted as a result of the “required accuracy.” Accuracy of measurement means the closeness between the result of a measurand and its true value (ISO 1990). Because “accuracy” is a qualitative concept, one should not use it quantitatively. The results should instead be associated with their uncertainties. Uncertainties associated with analytical measurements represent the doubt or level of reliability associated with the measurement.
