TOLERANCES FOR
ALUMINUM PROFILES
ACCORDING TO
DIN EN 12020-2*
ABPH 800 (Full Profile)
The tolerances for the nominal dimensions (see table 1) depend on the following ratios:
- diameter of the minimum circumscribing circle du divided by the minimum wall thickness smin.
- maximum wall thickness smax divided by the minimum wall thickness smin.
