Do you scrap the entire batch? Or is the part actually good?
Imagine you’ve just manufactured a batch of 10,000 precision shafts. The drawing says: Diameter: 10.0 mm ± 0.1 mm . Your high-tech laser micrometer measures one shaft at 10.105 mm — 5 microns over the limit. INTERNATIONAL STANDARD ISO 14253 1.pdf
It turns measurement from a source of conflict into a tool for shared confidence. And in a world of tight tolerances and high-stakes production, that’s not just technical — it’s strategic. Next time you see a part hovering near the limit, don't ask "Is it good or bad?" — ask "What is my measurement uncertainty, and what does ISO 14253-1 say I should do?" Do you scrap the entire batch
