Abstract :
A resistance comparison carried out with a temperature and pressure stabilized 100 /spl Omega/ standard resistor was performed in November and December 1998. The participants were BIPM, BNM-LCIE (France), PTB (Germany) and VTT (Finland)-pilot. The comparison results agree within 4/spl middot/10/sup -9/ with a combined standard uncertainty of 11/spl middot/10/sup -9/.
