The results from the first international comparison of profile and helix measurements between the national metrological institutes (NMIs) or their representatives of Germany, USA and UK are presented. The comparison was organized and coordinated by the UK National Gear Metrology Laboratory. The results from measurements on a 200 mm diameter helix master and a 200 mm diameter profile show that differences in slope error parameters are within the measurement uncertainty claimed by individual NMIs. The results should become the basis for the mutual acceptance of measurands for gears, in the calibration measurement capability list of EUROMET.
