Abstract :
Conductivity measurements are an important tool for quality control of aluminum alloys in aircraft manufacture. Industrial measurements using commercial conductivity meters are performed using eddy currents (60 kHz) whereas many conductivity standards are traceable through measurements at DC. A combined project of NPL, PTB, and NMi has been started aiming a.o. at improving the agreement of conductivity measurements with DC and AC methods. In this paper we describe the first results of a new methodology for DC conductivity measurements in the Van der Pauw geometry.
