Iso 2768-m — Tolerances |work|

"ISO 2768-mK," Elias read aloud. "We looked at the 'm'. That covers linear dimensions—lengths, widths, heights. But that second letter... 'K'. That covers geometrical tolerances. Straightness, flatness, symmetry."

The permissible deviation for linear dimensions depends on the . iso 2768-m tolerances

The next morning, Elias stood in the shipping bay as the truck loaded the crates. His phone buzzed. It was the client. "ISO 2768-mK," Elias read aloud

| Tolerance Class | Straightness & Flatness (mm per 100 mm) | Perpendicularity (mm per 100 mm) | Symmetry & Runout (mm per 100 mm) | |----------------|------------------------------------------|-----------------------------------|------------------------------------| | | 0.2 | 0.3 | 0.2 | But that second letter

When applying ISO 2768-m, the following note is added to the drawing’s title block or general notes:

The rain lashed against the corrugated metal roof of the Precision Dynamics factory, a rhythmic drumming that usually soothed Elias. But tonight, the rhythm was broken by the shrill beep of the Coordinate Measuring Machine (CMM).

"The drawing says ISO 2768-m," Elias muttered, more to himself than Marcus.
