Explications

This program calculates an estimated value for the expanded measurement uncertainty for gas and vapour measuring methods. The calculation is based on the specifications of the following standards:

 

EN 482 Workplace exposure – General requirements for the performance of procedures for the measurement of chemical agents (June 2012)
EN 1076 Workplace exposure – Procedures for measuring gases and vapours using pumped samplers - Requirements and test methods (April 2010)
The data obtained in accordance with the quoted standards during the validation of a measuring method are required for the calculation of measurement uncertainty.

The program calculates the measurement uncertainty for three concentrations, as specified as the minimum requirement by EN 1076, or for four concentrations.
