CEN/TC 175/WG 1 - General matters, definitions, measurement methods

This European Standard defines general terms relating to sawn timber and round timber used in European Standards.

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.

This Technical Specification defines a destructive method of assessing the case-hardening of a piece of sawn timber with reference to the distortion measured in a slice taken from the piece.
This Technical Specification is applicable to sawn timber and timber which has been planed or surfaced by other means. It applies to both hardwood and softwood with a thickness not greater than 100 mm.

This European Standard lists commercial hardwood and softwood timbers used in Europe.

This European Standard defines the method for determining the moisture content of a piece of sawn timber.
This method is considered as the reference method.
This standard applies to sawn timber, and timber which has been planed or surfaced by other means.

This European Standard defines a non-destructive method for estimating the moisture content of a piece of sawn timber using an electrical resistance moisture meter.
This standard applies to sawn timber, and timber which has been planed or surfaced by other means.

This European Standard specifies the methods of measuring dimensions of sawn timber. This standard applies to hardwood and softwood sawn timber, both square edged and unedged. This standard does not apply to tropical timber.

This European Standard defines additional terms relating to round and sawn timber used in European Standards and contains the general index. NOTE The numbering of the terms is based on the number of this standard and is independent of the clause number.

This part of this standard defines terms relating to degrade by insects used in European Standards. The definitions in this part standard are for general commercial use. NOTE: In case of dispute, attention is drawn to the definitions given in standards prepared by CEN/TC 38 "Durability of wood and derived materials".

This part of this standard defines terms relating to stain and fungal attack used in European Standards. The definitions in this part standard are intended for general commercial use. NOTE: In case of dispute, attention is drawn to the definitions given in standards prepared by CEN/TC 38 "Durability of wood and derived materials".

This part of the standard defines terms relating to features of round timber used in European Standards.

This part of standard contains general terms relating to sawn timber used in European Standards and the definitions of these terms.

This part of standard contains general terms relating to sawntimber used in European Standards and defintions of these terms.

This standard specifies the methods of measuring features taken into account in the visual grading of sawn, processed and round timber for appearance or to assess its mechanical properties.  It does not apply to the strength grading of structural timber (see EN 518 and EN 519). This standard applies to hardwood and  softwood sawn timber, both square edged and unedged, to processed timber and to round timber. This standard does not apply to tropical timber.

This European Standard specifies the methods of measuring biological degradations (insect, fungi, etc.) taken into account in the visual grading of sawn and round timber for appearance or to assess its mechanical properties. It does not apply to the strength grading of structural timber (see EN 518 and EN 519). This standard applies to hardwood and softwood sawn timber, both squareedged and unedged, to processed timber and to round timber. This standard does not apply to tropical timber.

This European standard defines a destructive method of assessing the case hardening of a piece of timber with reference to the distorsion measured in a slice taken from the piece. This standard applies to sawn timber and timber which has been planed or surfaced by other means. It applies to both hardwood and softwood with a thickness not greater than 100 mm.
