Sorting characteristics
KVH requirements
(not visible zone KVH NSi)
Notes
Production class
C24
 
Sorting regulation in case
of a visual sorting
DIN 4074-1Other sorting regulations have to be agreed separately.
Product regulationDIN EN 14081-1 for not finger-jointed KVH®,
DIN EN 15497 for finger-jointed KVH®
 
Wood moisture15 % ± 3 %
Technically dried: timber that is dried in
a specific process driven technology system
at a temperature of T ≥ 55°C for minimum 48h
at a timber moisture u ≤ 20%.
The defined timber moisture is the prerequisite of a
extensive waiver of precautionary chemical
timber protection; possibly also a prerequisite of the production
of finger joints.
Cut typeThe cut is performed bearing in mind
that in an ideally grown trunk
the single piths are cut through in case of
double stem cut.
 
Rough edges≤ 10% of the minor section side 
Dimensional accuracy
of the cross-section
DIN EN 336, dimensional stability class 2:
≤ 10 cm: ± 1 mm;
The dimensional stability for length measuring is
to be agreed between the purchaser and the supplier.
Branch conditionDIN 4074-1, sorting class S10 TS 
BranchesS10: A ≤ 2/5,
no more than 70 mm
In case of machine sorting, the following applies:
for KVH®-NSi the size of branches is not taken into consideration.
Bark embeddingDIN 4074-1, sorting class S10 TSBark of branches are added to the branch.
CracksCrack width ≤ 5 %Crack width referred to the respective cross-section side.
Without limitation of the length or the number of
cracks. The building supervisory authority and
crack depth have to be met.
Crack depth - Shrinkage cracksNot allowed up to 1/2Measured according to DIN 4074-1
Resin pocketsWidth ≤ 5 mmCorresponds to the quality classes 1 and 2 according to DIN 68365. Without
limitation of the length or the number of
Resin pockets.
DiscolourationsBlueness: allowed
Nailed down brown and red stripes: up to 2/5
Blights, white rots: not allowed
Measured according to DIN 4704-1.
The requirements for KVH®-NSi correspond
to the sorting class S10 according to DIN 4074-1.
Insect infestationallowed are worm grooves up to 2 mmAccording to DIN 4074-1
Twisting1 mm every 25 mm heightMeasured according to DIN 4074-1
Longitudinal curvature≤ 8 mm / 2 mMeasured according to DIN 4074-1. Corresponds to the requirements
of the sorting class S10 according to DIN
Finishing of the endssquare-ended cut (by agreement) 
Surface characteristics
