Iso 20457 Tg5 ((link)) May 2026

: Standard Baseline Precision. This is the "default" for technical parts where fit and function are important but not microscopic.

: Whether using a CMM (Coordinate Measuring Machine) or a manual fixture. Why Choose TG5? Iso 20457 Tg5

Using balances cost and quality. Tighter groups (TG1–TG4) significantly increase tooling costs and scrap rates because they require narrower process windows. TG5 provides sufficient accuracy for: Consumer electronics housings. Automotive interior trim. Medical device enclosures.
