A diameter measurement of the precise cylinder bores is the specific problem of the length metrology. In industrial practice this operation is being realised by means of threepointed bore gauges -inside micrometers. The ring gauges -setting rings are used for testing of the inside micrometers. Ring gauges are manufactured from the wear resistant steel or zirconium ceramic with tolerance diameter of 1 μm and form tolerances according to DIN 2250. Since the setting rings of highest accuracy are
