New Rules and Regulations (EU)
Needs of new statistical wood
aggregates conforming with national
and international classification and
standardisation rules (Uni, EN etc.)
Needs of quantitative standards for
wood aggregates in statistic surveys

Criteria for the new statistical classification

Uses of wood:
 uses

of wood requiring processing:
…when future uses require processing,
classification takes in to account the kind
of process to which wood shall be
submitted. Woody raw material’s values
and prices can strongly depend on kind of
process
 uses
of wood requiring no or
minimum processing:

poles, beams for construction, housing
etc.

other wood such as that used for posts,
fencing, pitprops tanning, match blocks
etc..

Criteria for the new statistical classification

Uni standardisation rules taken as
reference :

UNI 3512 - Pine and Larch poles for
telephone lines - common type

UNI 3513 - Pine and Larch poles for
telephone lines - heavy type

UNI 3514 - Cestnut poles for telephone
lines - common type

UNI 3515 - Cestnut poles for telephone
lines - heavy type

Criteria for the new statistical classification

New sawlogs definitions adopted by
CCC:

Sawlogs are characterised by physical
properties such as:
• cylindrical
and
straight-grained
without major bending;
• a diameter of not less than 15 cm
• sawn lengthways for manufacture of
sawnwood, cross-ties, or used for
production of sheets for veneering
(mainly by peeling or slicing).

Dimensional standards: minimum
diameter (cm), roundwood length (m)
