DESIGN FEATURES
The bottom side of the measuring surface has to be provided with at least three support points. The design of the plate will be such as to allow the forces acting on the table to be directed towards the support points in order to minimize distortion.

SURFACE QUALITIES  
DIN 876/III planed / milled
DIN 876/II fine planed / milled, alternatively scraped
DIN 876/I fine milled, alternatively fine scraped
DIN 876/0 fine scraped with bluing

FLATNESS
Measured at standard temperature of 20° C (68° F). Allowable variation of the measuring surface to a true plane in microns (µ) or mil = 0.001 inch where L is the length of the longest side of the plate.

Metric (L in mm) SAE (L in inch)
DIN 876/III µm = 40 + (L / 25) mil = 1.575 + (L / 25)
DIN 876/ II µm = 20 + (L / 50) mil = 0.787 + (L / 50)
DIN 876/ I µm = 10 + (L / 100) mil = 0.394 + (L / 100)
DIN 876/ 0 µm = 4 + (L / 250) mil = 0.157 + (L / 250)
