The values of deviation of D are valid for two-point measurements only. Deviations of D for Class 0 apply only to diameter series 0, 2 and 3, and do not apply to either of the following cases: over 80 mm of D in diameter series 0, or over 315 mm of D in diameter series 2. Deviations of D for Class 6 apply only to diameter series 0, 2 and 3, and do not apply to the case of over 95 mm of D in diameter series 0. REMARKS: The low deviations of outside diameter specified in this table do not apply within a distance of twice the nominal ring chamfer dimensions from the ring face. 261
