KERN & SOHN FKTF - Manual (Page 6)

Packaged goods manufactured and tested according to the rules stipulated by the Pack-
aged Goods Regulation bear the following marking on their label:
Weighing scales to be used in packaged goods control must have type approval according
to
category III combined with a valid verification.
The choice of a non-automatic weighing scale should be on the one hand according to the
required maximum weight and on the other hand the maximum admissible verification value
(e) for the nominal filling quantity to be tested: According to the admissible maximum num-
ber of errors for the verified weighed result (e):
Nominal filling quantity QN
for packaged goods in g or ml
Maximum admissible verification value
in g
Less than 10 0.1
For 10 to less than 50 0.2
Nominal filling quantity QN
For packaged goods in g or ml
Maximum admissible verification value
in g
For 50 to less than 150 0.5
For 150 to less than 500 1.0
For 500 to less than 2500 2.0
For 2500 and more 5.0
Finally, it should be noted that shorter re-verification periods are applied in many European
States for weighing scales used in package controlling as opposed to those for regular
weighing scales of verification category III. Usually this is every year or every two years.
