Distances between the centers of lines will be calibrated on one 100 mm glass line scale. The measurements will be performed in a predefined section (along the line height).
The artifact will be provided by NPL (NPL product)
The comparison will be a key comparison in the framework of the Mutual Recognition Arrangement (MRA) of the Metre Convention and shall support confidence in calibration and measurement certificates issued by the participating national metrology institutes.
[30 Nov 2005] This project – comparison was agreed at the EUROMET TCL meeting in 2005. Participants from all RMO’s will be invited.
