- ÍtemMetodología de evaluación de la incidencia del factor humano en la medición intra-laboratorio de volúmenes de líquidos mediante el método gravimétrico y de transferencia en recipientes volumétricos metálicos.(Fundación Universitaria Los Libertadores. Sede Bogotá., ) Aguirre Romero, Elvis; Bermudez Rubio, DagobertoTheSuperintendenciaofIndustriaandComercio(SIC)CalibrationLaboratoriesimplementintra-laboratoryverification studies to demonstrate the reliability of the calibration methods for metallic volumetric containers (RVM) used in the inspection and verification activities of metrological control. The diversity of liquid volume measurement methods and volumetric instruments used generates the need to support with statistical techniques that the results obtained by the gravimetric and transfer measurement method are comparable. The objective of this research is to evaluate the incidence of the human factor in the intra-laboratory measurement of liquid volume by gravimetric and transfer methods in RVM with a capacity of 20 liters. An experimental design of two nominal factors with 3 and 2 levels respectively was considered. From the design,was constructed the complete 3x2 factorial arrangement with five replicates , which will allow obtaining all the relevant information regarding the effect of these factors on the total volume measurements. The two-factor ANOVA test shows that there are no significant differences between the means of the volumetric measurements by the two treatments: analysts and measurement methods . The proposed statistical model allows traceability of the influence of the human factor in the measurement of volumes of liquids in RVM by different methods.
