CEN/TC 175/WG 4 - Round timber

This European Standard specifies a qualitative classification and grade designations for felled round timber of oak and beech presented in the form of long poles or logs.
The classifications describe quality classes of round timbers for which the intended use is not known.
The classification applies for the following species: Oaks, Quercus sessiliflora SALISB. (or Quercus petraea LIEBL.), Quercus robur L. (or Quercus pedunculata EHRH.) and Beech (Fagus sylvatica L).

This European Standard specifies a qualitative classification and grade designations for felled round timber of poplar in the form of long poles or logs. The classifications describe quality classes of round timbers for which the intended use is not known. This classification is applicable to all merchantable clones of poplar.

This European Standard specifies a dimensional classification for round timber (softwood and hardwood) for which the intended use is not known.

TC - Modification to Table 1.

This European Standard specifies the qualitative classification for the roundwood of spruces (Picea spp) and firs (Abies spp). The classification is made either using Clauses 4 and 5 or using Annex A. Clauses 4 and 5 describe the qualitative classification of round timber for which the intended use is unknown.
Informative Annex A gives a list of characteristics which serves as a guideline for contracts describing qualities for round timber of spruces and firs where the intended use is known.

This Standard specifies the qualitative classification for the roundwood of larches (Larix) and Douglas fir (Pseudotsuga). The classification is made either using Clauses 4 and 5 or using informative Annex A. Clauses 4 and 5 describe the qualitative classification of round timber for which the intended use is unknown.
Annex A gives a list of characteristics which serves as guideline for contracts describing qualities for round timber of larches and Douglas fir where the intended use is known.

This European Standard specifies the qualitative classification for the roundwood of pines. It applies to Scots pine (Pinus sylvestris), Corsican or Austrian pine (Pinus nigra), maritime pine (Pinus pinaster) and radiata pine (Pinus radiata). The classification is made either using Clauses 4 and 5 or using Annex A. Clauses 4 and 5 describe the qualitative classification of round timber for which the intended use is unknown.
Informative Annex A gives a list of characteristics which serves as a guideline for contracts describing qualities for round timber of pines where the intended use is known.

This European Standard defines the principles which are to be used in the derivation of round timber measurement and volume calculation rules. This standard applies to rules for measuring hardwood and softwood felled round timber. It does not apply to tropical timber.

This standard defines the rules for the qualitative classification of round timbers of oaks and beech presented in the form of tree-length, log or billet. The oaks classification is applied only for the following species: sessile oak (Quercus sessiliflora SALISB, or Quercus petraea LIEBL) and pedonculated oak (Quercus robur L. or Quercus pedonculata EHRH).

This European Standard specifies a qualitative classification and grade designations for felled round timber of poplar in the form of long poles of logs. The classifications describe quality classes of round timbers for which the intended use is not known. This classification is applicable to all merchantable clones of poplar.

This European Standard specifies a qualitative classification and grade designations for felled trees of ash (Fraxinus excelsior) and maples presented in the form of long poles or logs. The classifications describe quality classes of round timbers for which the intended use is not known. The maples classification is applied for the following species: sycamore maple (Acer pseudoplatanus) and maples (Acer platanoïdes), (Acer campestris).

This European standard describes a dimensional classification for softwood being conifer roundwood for which the intended use is not known.

This Standard specifies a general dimensional classification for felled hard- wood timber and specifies the denominations to use.

This standard specifies the qualitative classification for the roundwood of spruces (Picea spp) and firs (Abies spp). The classification is made either using clauses 4 and 5 or using clause 6. Clauses 4 and 5 describe the qualitative classification of round timber for which the intended use is unknown. Clause 6 gives the characteristics to be included in all national standards describing a qualitative classification or as guideline for contracts describing qualities for round timber of spruces and firs where the intended use is known.

This Standard specifies the qualitative classification for the roundwood of larch (Larix) and douglas fir (Pseudotsuga). The classification is made either using clauses 4 and 5 or using clause 6. Clauses 4 and 5 describe the qualitative classification of round timber for which the intended use is unknown. Clause 6 gives the characteristics to be included in all national standards describing a qualitative classification or as guideline for contracts describing qualities for round timber of larches and douglas firs where the intended use is known.

This standard specifies the qualitative classification for the roundwood of pines. It applies to scots pine (Pinus sylvestris), Corsican or Austrian pine (Pinus nigra), maritime pine (Pinus pinaster) and radiata pine (Pinus radiata). The classification is made either using clauses 4 and 5 or using clause 6. Clauses 4 and 5 describe the qualitative classification of round timber for which the intended use is unknown.
