Round and sawn timber - Methods of measurements - Part 3: Features and biological degradations

This European Standard specifies the methodology for measurement of features - in relation to wood structure, biological agencies and other damage - taken into account in the visual grading:
a)   for appearance - of sawn, processed and round timber;
b)   for serviceability - of sawn and processed timber (identified in EN 1611-1 as the integrity of the timber).
When the standard is applied the methodology of measurement used shall be stated.
It is not applicable to structural timber for which strength grading in accordance with EN 14081-1 is required.
This standard applies to hardwood and softwood sawn timber, both square edged and un-edged, to processed timber and to round timber.
It does not apply to tropical timber.

Rund- und Schnittholz - Messmethoden - Teil 3: Merkmale und biologische Schädigungen

Diese Europäische Norm legt das Verfahren zur Messung von Merkmalen in Bezug auf Holzkonstruktionen, biologischen Stoffe und anderen Schäden bei der visuellen Sortierung nach Folgendem fest:
a)   nach dem Aussehen von Schnittholz, weiterbearbeitetem Holz und Rundholz;
b)   nach der Brauchbarkeit von Schnittholz und weiterbearbeitetem Holz (bezeichnet in EN 1611-1 als Integrität des Holz).
Wird die Norm angewandt, muss die genutzte Vorgehensweise der Messung angegeben werden.
Sie gilt nicht für die Sortierung von Bauholz nach der Festigkeit, die nach EN 14081-1 gefordert ist.
Diese Norm bezieht sich auf parallel besäumtes und unbesäumtes Schnittholz sowie auf bearbeitetes Holz und Rundholz von Laub- und Nadelholzarten.
Auf Tropenholz ist diese Norm nicht anzuwenden.

Bois ronds et bois sciés - Méthode de mesure - Partie 3 : Singularités et altérations biologiques

La présente Norme européenne spécifie la méthodologie de mesure des singularités (relatives à la structure du bois, aux altérations biologiques et aux autres dégradations) prises en compte pour le classement visuel :
a)   de l’aspect des bois sciés, usinés et ronds ;
b)   de l’aptitude à l’emploi des bois sciés et usinés (identifiée dans l’EN 1611-1 sous la dénomination « intégrité du bois »).
Lorsque la norme s’applique, la méthodologie de mesure utilisée doit être spécifiée.
Elle ne s’applique pas aux bois de structure pour lesquels un classement de résistance conforme à l’EN 14081-1 est requis.
La présente norme s’applique aux bois feuillus et résineux, sciés, avivés ou non, aux bois usinés et aux bois ronds.
Elle ne s’applique pas aux bois tropicaux.

Okrogli in žagani les - Metode merjenja - 3. del: Značilnosti in biološka razgradnja

Ta evropski standard določa metodologijo za merjenje funkcij – v povezavi s strukturo lesa, biološkimi agencijami in drugo škodo – ki se upoštevajo pri vizualnem ocenjevanju:
a) videza – žaganega, obdelanega in okroglega lesa;
b) uporabnosti – žaganega in obdelanega lesa (v standardu EN 1611-1 je to navedeno kot celovitost lesa).
Kadar je standard uporabljen, je treba navesti metodologijo uporabljenega merjenja.
Standard se ne uporablja pri konstrukcijskem lesu, pri katerem je zahtevano razvrščanje po trdnosti v skladu s standardom EN 14081-1.
Ta standard se uporablja pri žaganem lesu listavcev in iglavcev, tako z oblikovanim robom kot brez njega, obdelanem lesu in okroglem lesu. Ne uporablja se za tropski les.
