Uncertainty evaluation for the adiabatic temperature rise in isoperibol calorimetry

摘要

This article describes a practical approach for evaluating the uncertainty of results for determinations of the adiabatic (corrected) temperature rise in isoperibol calorimetry. The methodology is firmly based on the recommendations of the Guide to the expression of uncertainty in measurement (GUM). Although developed for a specific modification of the Regnault-Pfaundler method, the approach is sufficiently general to make it applicable to virtually any other scheme for the evaluation of temperature-time curves in temperature-rise calorimetry.
