| Standard / Grade | Equivalent to TG5? | Key Difference | |----------------|--------------------|----------------| | DIN 16901 (110) | No – 110 is coarser (~TG8). TG5 is ~130-140 range in old standard. | Old 110 is general purpose; TG5 is precision. | | ISO 20457 (P3) | Roughly equivalent | ISO P3 is similar but less detailed on geometric tolerances. | | VW 13010 (Group 4) | Slightly tighter | TG5 is similar to VW13010’s higher precision group. |
| Nominal Size Range (mm) | Approximate Tolerance Class TG5 (mm) | Practical Interpretation | |------------------------|--------------------------------------|---------------------------| | 0 – 10 | ±0.05 to ±0.08 | Very tight; requires stable process & precision mold. | | 10 – 50 | ±0.08 to ±0.12 | Typical for functional bearing/shaft fits. | | 50 – 160 | ±0.12 to ±0.20 | Demanding for larger parts; watch for warpage. | | 160 – 400 | ±0.20 to ±0.35 | High precision for large geometries; design must minimize stress. | Note: Actual values depend on material shrinkage, part geometry, and feature type (free dimension vs. fixed dimension). Always refer to the latest DIN 16742 tables. din 16742 - tg5
DIN 16742 is the German industry standard governing . It replaces the older standards DIN 16901 and VW 13010, providing a unified, modern system for defining form, orientation, and dimensional accuracy. | Standard / Grade | Equivalent to TG5
