Comparison of angle gauges

Project Description

A set of thirteen angle gauges and precision square will be measured during the bilateral comparison. Different measuring methods and instruments will be applied: either an autocollimator and an index table /OFMET/ or a goniometer /GUM/. The goal of the project for OFMET is to test new measuring equipment, for GUM - to compare results GUM-OFMET. Piramidality will be determined by OFMET.

The result of this comparison will be interesting for future discussion about the definition of measurand and recommended method for angle gages calibration.
