3.5.2 By agreement between manufacturer and consumer is allowed to produce profiles of other lengths.

3.6 Profile of N 2 produce the measured length — 3900 mm. is possible to supply random lengths, but no shorter than 2250 mm, mass of which does not exceed 5% of the batch weight.

3.7 tolerances for the length of profiles dimensional and multiple lengths shall not exceed:

for profile N 1 +100 mm;

— profile N 2 +40 mm;

— profile N 3 +70 mm.

When delivering profiles with a length of one times the limit deviations should not exceed ±25 mm.
