Din 16742 - Tg5 -

| 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. |

For critical features, it is strongly recommended to specify TG5 only on functionally relevant dimensions, while allowing coarser grades (e.g., TG8–TG10) on non-critical geometries to balance cost and performance. 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

Title: Precision Requirements for Injection Moulded Parts – Tolerance Grade TG5 per DIN 16742 | Old 110 is general purpose; TG5 is precision

While the full standard includes complex tables based on nominal size ranges, TG5 can be summarized as:

Within this standard, represents a high-precision classification. It is typically applied to parts that require tight functional fits, consistent assembly behavior, or superior geometric stability without resorting to post-molding machining.
