The sphere size is inspected using a Heidenhain CT-60 gage, to an uncertainty of ± 10μin. The size of the 1in ball is ± .0000025in.
The sphericity is measured on a Talyrond to an uncertainty of 2 μin.
The sphere material is an ultra fine grain, high chrome, high carbon stainless steel that is hardened to 58 Rc and ultra-cold cycled for long-term dimensional stability.
All measurements are made at international standard temperature of 68ØF (20ØC).
The above specifications meet all the quality requirements for Performance Evaluation of Coordinate Measuring Machines per ANSI/ASME-B89.4.1-1997.
