| Zusammenfassung | A medium and high vacuum primary standard, based on the static expansion method, has been set up at CENAM, Mexico. This system has 4 volumes and covers a measuring range from 1×10-5 Pa to 1×103 Pa of absolute pressure. As part of its realisation, a characterization was performed, which included volumes calibration, several tests and a bilateral key comparison. To determine the expansion rates, two methods were applied: a) the gravimetric method, b) the method with a linearized manometer (spinning rotor gauge, SRG). The outgassing rates for the whole system were also determined. A comparison was performed with PTB, Germany (comparison SIM-Euromet.M.P-BK3). By means of this comparison, a link has been achieved with the Euromet comparison Euromet.M.P-K1.b. As a result, it is concluded that the value obtained at CENAM is equivalent to Euromet’s reference and therefore, the design, construction and operation of CENAM’s SEE-1 vacuum primary standard was successful. |
