. These values and the radial runout table (see appendix

) should be submitted to the buyer on the premise of turning test in the workshop. The manufacturer shall disclose the calculation results.
The details and basis of the hypothesis.
The horizontal and vertical radial runout measured in the workshop should be equal to the predicted cold radial runout.
The deviation range is within 0.0 15% of the travel.
