2.9.3 Principle of tolerance check
The lower tolerance ranges TU1 and TU2 are stipulated per nominal weight
Qn by the Prepackaging Regulations. If required, the upper tolerance range
TO may be increased or reduced by the factor TO (see formula). This permits
the number of accepted packages to be increased. The input of TO is described
on page 3 -- 94.

Range which can be
changed by the To factor
with To (1..30) = 3, TO reaches up to 236 g (see table)
Tx = Qn -- TU1
220 g -- 191 g = 9 g
Tx
TO = Qn +Tx + (factor To x Tx)
200 g + 9 g + (9 g x 3 = 27g) = 236 g

Confidence mean value
All packages are accepted
Packages are accepted if the confidence mean value
≥
nominal
weight, but only 2% of the total number of the packages accepted.
All packages are accepted if the confidence
mean value =/> nominal weight Qn
TO = upper tolerance limit
TU = lower tolerance limit
A too light, non--accepted package is
processed according to the values
preset in the left neighboured column.
A too heavy, non--accepted package is
processed according to the values pre-
set in the right neighboured column.
