| Outside diameter (mm) | Thickness (mm) | Thickness tolerance (%) | Outside diameter tolerance (%) |
| 3-50 | 1-5 | +/-5 | +/-1 |
| 50-100 | 2-5 | +/-5 | +/-1 |
| 100-200 | 3-6 | +/-5 | +/-1 |
| 200-460 | 4-8 | +/-5 | +/-1 |
About the tolerance, when the thickness is thin, the tolerance is also smaller. (min:±0.1)
