PRESSURE STANDARDS COMPARISON WITHIN THE INTERAMERICAN METROLOGY SYSTEM (SIM), UP TO 100 MPa.

摘要

A pressure comparison was carried out within the Interamerican Metrology System (SIM), in order to estimate the level of agreement for the realization of the quantity and the uncertainty associated to its measurement. The comparison participants were at least, one National Metrology Institute (NMI) from each of the five SIM areas. The comparison was carried out up to 100 MPa, using an electronic comparison standard with 1·10~(-4) of full-scale accuracy. The Centro Nacional de Metrologia, CENAM, in Mexico, was the coordinator and pilot laboratory. The results obtained the deviations graphs that include the uncertainty for each participating laboratory are presented in this document.
