摘要

A EUROMET collaborative project has been set up between Instituto Nacional de Tecnica Aeroespacial (INTA) and E+E ELEKTRONIK Ges.m.b.H, the two designated laboratories of the Spanish and Austrian National Metrology Institutes, Centro Espahol de Metrologia (CEM) and Bundesamt fur Eich- und Vermessungswe-sen (BEV), respectively. The objective of the project is to provide INTA with a new standard that covers the dew-point temperature range from - 27℃ to +90℃ with a gas flow up to 5L·min{sup}(-1) in the "two-pressure" mode, extended to 95℃ when operated as a continuous flow "single-pressure" generator, and investigate the importance of the enhancement factors in the uncertainty estimations used in support of the participants' calibration and measurement capabilities (CMC) (The CIPM Mutual Recognition Arrangement, http://www.bipm.fr/en/cipm-mra/). The equivalence of the Spanish and Austrian national standards is also to be evaluated, further supporting the outcomes of the Key Comparisons, in which both have already participated. The preliminary results obtained to date are reported and discussed in the context of the project and the consistency of the declared CMC's.
