- Tg5 - Din 16742

To understand the significance of TG5, one must first understand the structure of DIN 16742. The standard categorizes tolerances into two main groups: dimensional tolerances (for length, width, height) and form tolerances (for flatness, straightness, etc.). These tolerances are not arbitrary; they are based on the nominal size of the dimension and are grouped into "Tolerance Groups."

For technical guidance on applying this standard, designers often use tools like the PolTolerances Software din 16742 - tg5
