International collaboration: comparison of Russian and Slovakian national pressure-unit standards in the range 10~-2 to 10~3 Pa

摘要

Russian and Slovakian national standards for the pressure unit have been compared for the low absolute pressure range. Estimates have been made of the random error and residual systematic error in the comparisons, as well as of the confidence limits for the error. It is concluded that the pressure scales for the participating countries are in agreement in the range 10~-2-10~3 Pa.
