Masterclass Compliance testing, Periodic monitoring and Statistics (English)

Masterclass   September 15 2022

It is very important for a company to know whether the measured exposure to a hazardous substance complies with the occupational exposure limit value. The European guideline EN-689 prescribes that a statistical test is used for this compliance check. Topics covered in this masterclass include: validation of measurement results, testing against the limit value for both a small and large set of measurements, calculating the probability of exceeding the exposure limit value (95-percentile and 70% confidence limit), and determining the time interval for periodic measurements. You will receive a handy free Excel-tool for statistical tests, useful tips and practical examples.


This masterclass is the tenth of the Chemrade Masterclasses Chemical Risk Assessment. These masterclasses have been developed for Chemrade customers, partners and close relations who want to deepen and update their knowledge of Chemical Risk Assessment. There are 11 online masterclasses of approximately 1 hour that will be given in the coming year. The masterclasses cover the entire process of risk assessment of hazardous substances in your company: from strategy, via exposure estimation with models, exposure measurements, biological monitoring, health monitoring, to compliance testing and control measures. Each masterclass provides a brief overview of current knowledge (state-of-the-art), issues, useful tools / solutions and examples from practice.

Chemrade customers, partners and close relations are cordially invited to register for these Chemrade Masterclasses. There are no costs associated with this. Each masterclass can also be taken separately. Participants receive a certificate of participation. The masterclasses are given in both Dutch and English.
