CEN/TC 175/WG 32 - Specific user requirements - Timber in joinery

This Technical Specification specifies the method of control and tests for glue bond performance of lamination and finger jointing processes employed in the production of timber blanks and semi-finished profiles (products) for joinery applications.
The methods of control are set out to ensure the durability of the glue line according to the service class.
The specific requirements for dimensions, stability and moisture content are given in EN 13307-1.

This European Standard specifies the general requirements including in particular the grading and classification by appearance quality of timber in joinery products or individual joinery parts.
This European Standard is intended to be used at the time of manufacture of a product.  However this Standard may be used to evaluate products at a later stage, but in these situations storage and service conditions, subsequent to manufacture, shall be taken into account (surface checks).
Where European product standards exist their timber requirements shall take precedence, unless an alternative improved specification is given as identified in Annex D.  If reference to this European Standard is made the specific grade and requirements shall be identified.
This European Standard covers solid, finger-jointed, end-jointed, edge-jointed and laminated timber products.
Matters relating to the influence of timber characteristics on strength and durability are not covered in this Standard.

This European Standard specifes principle material requirements for timber and wood-based products in internal windows, doors and doorframes (with or without fixed parts), including appearance, biological durability and other physical characteristics.
This European Standard applies to factory assembled internal windows, door leaves and doorframes uncoated or intended to be coated.
If doors are covered by other decorative veneers or films the respective veneer or film Product Standard shall apply.
EXAMPLE   Timber veneers may be graded to EN 635: Parts 1, 2, 3 and 5, and ENV 635 4.

This European Standard specifies principle material requirements for timber and wood-based products in external windows, external door leaves and external doorframes (with or without fixed parts), including those relating to appearance, biological durability and other physical characteristics.
This European Standard applies to assembled windows, external door leaves and external doorframes uncoated or intended to be coated.
If windows or doors are covered by other decorative veneers or films their respective veneer of film Product Standard shall apply.
NOTE   For example: Timber veneers may be graded to EN 635: Parts 1, 2, 3 and 5, and ENV 635 4.

This European Standard specifies requirements for timber blanks and semi-finished profiles for non-structural uses, including glued laminated and glued finger jointed products.  This Standard gives specific requirements for dimensions, stability and moisture content.  This Standard applies to hardwood and to softwood for use in joinery.
Production control requirements and tests are given in prCEN/TS 13307-2.
