Flatness of surface
The permissible deflection of
formwork parts is defined in
DIN 18202 (flatness tolerances),
Table3, lines 5 to 7 (Table 11.1).
Here, the maximum permissible
deflection is defined in relation to
the distance between the meas-
uring points. The permissible
fresh-concrete pressure that is in
line with the flatness tolerances
as defined in DIN 18202,Table 3,
line 7 is 100 kN/m² for full load.
The measuring lath is placed on
the highest protruding points of
the surface and the deflection is
measured at the deepest point
in-between.
The distance between measuring
points corresponds to the
distance between the highest
protruding points.
