LES - Round and sawn timber

TC - Modification to Table 1.

This European Standard specifies the rules determining the quality of appearance graded sawn timber. It describes various grades of temperate hardwood rough sawn timber and regularized timber for which it lays down denominations and definitions. It also gives rules for composition and acceptance of batches. This standard gives minimum requirements for each grade classification. Sawn timber not included within limits given in this standard may be defined, if necessary, by contract specifications established on the basis of this standard. This standard applies to grading of green and dried timber. Characteristics apply at the time of grading. This standard does not apply to the strength grading of structural timber or to sawn timber for pallets. This standard is applicable to the following products: a) Oak sawn timber, in the following categories: 1) Un-edged boards: individual selected pieces and boules; 2) Square edged timber and strips (not exceeding 41 mm thickness); 3) Baulks (sum of thickness + width ≥ 200 mm and thickness ≥ 80 mm). b) Beech sawn timber, in the following categories: 1) Un-edged boards: individual selected pieces and boules; 2) Square edged timber and strips; 3) Prepared timber (dried timber).

This European Standard gives specifications and requirements for prefabricated stairs made of solid wood, i.e. where the components contributing to the fulfilment of mechanical resistance and stability characteristics are made of solid wood. These stairs are traditionally designed. This European Standard covers: stairs either pre-assembled, partly pre-assembled or in component form including balustrades and handrails for internal or external use. This European Standard does not consider the contribution of these elements to the overall structure design. The ability of a stair to contribute to the overall stability of the works or to the strength of the structure is not covered by this standard.
Carpets on stairs are not covered by this Standard. The surfaces of the wooden elements may be exposed or covered by finishes. Where stairs are supplied with a finish or covering, aesthetic or visual characteristics will not be covered by this Standard and references shall be made to the appropriate product standard (e.g. colour fastness of carpet finishes).

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 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 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 Standard defines the sampling plans and procedures for inspection by attributes of sawn timber lots exhibiting a homogenous distribution of properties.It also gives control regulations and conditions for conformity or non conformity of a lot in view of the agreed specification. This document applies to any sawn timber products claimed to comply with specifications defined in the sales contract. It does not cover the spread of different qualities within a grade or between the contracted grades. In case of a dispute, a sampling carried out only by customer or supplier is not valid as it cannot be guaranteed to be free from manipulation. Furthermore parties are free to enlarge the sampling or make use of another method provided an agreement is made between the interested parties.

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 Technical Specification gives definitions and characteristics for Thermally Modified Timber. TMT is used in interior (dry, humid) and exterior conditions.
NOTE 1   TMT is usually a semi-finished product ;  applications are e.g. flooring, panelling, cladding, decking, windows, doors,  furniture and other internal and external joinery. Their product standards give requirements and  test methods which are to be taken into consideration.
NOTE 2   Usage in load bearing applications - reference to relevant EN standards should be made.

This Technical Specification gives test methods for prefabricated timber stairs. These stairs are  made from timber and/or wood-based materials.
The methods included in this document can also be used for single components used in stairs (e.g. steps, handrails, balusters, …).
This document  does not consider the overall structure design of these elements. Stairs that are designed to contribute to the overall stability of the works or to the strength of the structure are not covered by this standard.
The surfaces of the timber elements may be exposed or covered by finishes.
NOTE 1   Where stairs are supplied with a finish or covering, some basic characteristics will not be covered by this standard and references should be made to the appropriate product standard (e.g. colour fastness of carpet finishes)
NOTE 2   Where the term "stair" is used in this document, it may also apply to individual element or component where appropriate
Tests can be carried out on a complete fully assembled system according to manufacturer installation instructions or on individual components.
A fully assembled stair test cannot be used to evaluate individual components.
There is no particular hierarchy of sequences or the need to carry out all the tests.
