A bilateral comparison of medium-vacuum standards at Physikalisch-Technische Bundesanstalt
(PTB) in Germany and the Korea Research Institute of Standards and Science (KRISS) in Korea
was performed in the pressure range from 3 Pa to 100 Pa in 2002. In this comparison, we used two
absolute-type capacitance diaphragm gauges as transfer standards. The dierence between the data
obtained at KRISS and those obtained at PTB was less than the combined standard uncertainty
(k = 2) for the two standards.
