Abstract

E l objetivo del presente estudio, es estimar la incertidumbre en la medición del área total de un triángulo aplicando la guía de estimación de la incertidumbre GUM ISO 1995 y utilizando el programa de cálculo simbólico MAPLE 11. La medición la realizó un grupo de 10 estudiantes de la maestría en Química y Gestión de la Calidad, utilizando el mismo objeto de medición y el mismo instrumento de medición. Se derivó el modelo matemático, se identificaron los componentes de las incertidumbres a través del diagrama de causa-efecto, se calcularon los coeficientes de sensibilidad utilizando el programa de cálculo simbólico Maple 11, se elaboró un balance de las incertidumbres y un diagrama de Pareto donde se reflejan las variables que más influyen en la incertidumbre del mensurando. Se calcularon las incertidumbres combinada y expandida con un factor de cobertura igual a t al 95% de nivel de confianza y 22 grados de libertad efectivos. Finalmente, se evaluó el intervalo de confianza, encontrándose un valor de (50.72 ± 0.39) cm2. La incertidumbre expandida relativa fue menor del 1%, indicando buena precisión en el proceso de medición.
