EVALUATION OF MEASUREMENT STANDARDS
Abstract
Centro Español de Metrología (CEM), Spanish Metrological Institute, as part of its activity, has started to prepare primary reference gas mixtures using gravimetrical method. As a consequence of this new work, a comparison of some primary reference gas mixtures prepared by CEM has been carried out with three of the gas mixtures manufacturers established in Spain. CEM has coordinated this comparison with the manufacturers in order to assure traceability in equipments for the automotive exhaust gas field. The objetive of this comparison is double: <BR />• to compare the analytical results with the gravimetric value of Primary Standard Material (PSM) preparation, <BR />• to compare the measurement capabilities between laboratories in measuring the amount of substance fractions of carbon dioxide in nitrogen.
