Scope

Scope: This guide consists of an overview of measurement uncertainty, basic methods for evaluating measurement uncertainty, analysis of the main uncertainty components in testing, and example analyses in the appendix; Main technical content: The main technique is to determine the sources of chemical analysis uncertainty in the construction field by organizing and summarizing the analysis methods of common chemical analysis steps in the construction field (such as weighing, preparation, titration, standard curve, etc.), and to evaluate the uncertainty of the entire analysis process. This ensures that the data and results provided by inspection and testing institutions are accurate and reliable. The main content includes: scope, normative reference documents, terms and definitions, common uncertainty influencing factors in chemical analysis, basic process for evaluating measurement uncertainty, evaluation of the main uncertainties in testing, and example analyses of uncertainty.
