title: [The quality of analytical data for a proper comparison with the limit value].
abstract: The analytical data is usually expressed as a number, in fact, due to the uncertainty of measurement, the "true value" of the analyte, by definition unknowable, is set within a range estimated with a confidence level (typically a probability of 95% with coverage factor 2). The comparison with a limit value must therefore take into account the confidence interval. The quality of the data in Industrial Hygiene is not limited to this. As established by UNI EN 482, the method of sampling and analysis must have an analytical sensitivity of at least one tenth of the limit value of the analyte.
