Comparación interlaboratorio para medición de masa convencional en cinco laboratorios: aportes a la infraestructura de la calidad en Panamá y República Dominicana

This article describes the results of a comparison between five metrology laboratories, located in Panama and the Dominican Republic, with measurements carried out from July to September 2022. The objective of the intercomparison was to evaluate the capacity of the laboratories to calibrate mass standards of class of accuracy F, in the range from 2 mg to 2 kg, as well as class M1 of 20 kg, in accordance with the provisions of the International Recommendation OIML R 111-1. Because the participants consistently had satisfactory results, it was not necessary to implement corrective actions in the participating laboratories to improve their mass standard calibration processes. The results of this study strengthen the confidence of the technical management of the five participating laboratories and, consequently, of the national quality infrastructure.
