Abstract
The key comparison EURAMET.L-K8.2013 on roughness was
carried out in the framework of a EURAMET project
starting in 2013 and ending in 2015. It involved the
participation of 17 National Metrology Institutes from
Europe, Asia, South America and Africa representing four
regional metrology organisations. Five surface texture
standards of different type were circulated and on each
of the standards several roughness parameters according
to the standard ISO 4287 had to be determined. 32 out of
395 individual results were not consistent with the
reference value. After some corrective actions the number
of inconsistent results could be reduced to 20, which
correspond to about 5% of the total and can statistically
be expected. In addition to the material standards, two
softgauges were circulated, which allow to test the
software of the instruments used in the comparison. The
comparison results help to support the calibraton and
measurement capabilities (CMCs) of the laboratories
involved in the CIPM MRA.
