Use of measurement uncertainty in compliance assessment with regulatory limits
Elcio Cruz de Oliveira
Professor at the Pontifical Catholic University of Rio de Janeiro
Technical Consultant at TRANSPETRO Rio de Janeiro, RJ, Brazil
“…ideally, the quality of the measurement process should have an uncertainty value in order to balance the costs of analysis and incorrect decisions…”
