[OPTM1-03] Traceable sphericity measurements of spherical sections at
PTB

*Markus Cornelius Schake1 (1. Physikalisch-Technische Bundesanstalt)

The first results of a long-term experiment to determine the form stability of
the transmission spheres employed for calibration purposes at PTB are presented. The results imply consistency
of the uncertainty in the sphericity measurement of the transmission spheres under varying reproducibility
conditions with the currently employed expanded measurement uncertainty.
