EN 13307-1:2006 (E) 4 Introduction This European Standard relates to semi-finished products intended to be used in a wide range of joinery products, including

20、 windows, doors and stairs. It provides a basis for contracts between the sellers of these semi-finished products and manufacturers of the end products. The specifier should be aware that not all of the characteristics defined and/or classified by this standard may be relevant in any given applicati

21、on, especially if those characteristics are subsequently made good by the manufacturer of the end product. At the time of publication, no relevant test standard for delamination or for temperature stability of adhesives exists. EN 13307-1:2006 (E) 5 1 Scope This European Standard specifies requireme

22、nts 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. Produ

23、ction control requirements and tests are given in prCEN/TS 13307-2. 2 Normative references The following referenced documents are indispensable for the application of this document.

29、solid timber piece, usually of a thickness of more than 7 mm, glued lengthways to create thicker sections NOTE 1 the piece may include finger joints and/or butt joints NOTE 2 Thicknesses of not more than 7mm are called veneers and are defined in EN 313-2. 3.6 service class 1 characterised by a moist

31、 of the surrounding air only exceeding 85 % for a few weeks of the year 3.8 service class 3 climatic conditions leading to a higher moisture content than in Service class 2 4 Requirements 4.1 Species The manufacturer shall identify the species used in the production of the blank or semi-finished pro

32、file. NOTE It is common and accepted practice in laminated profiles to mix certain species (e.g. spruce and fir). 4.2 Dimensions, geometrical characteristics 4.2.1 General Geometrical and physical characteristics shall be related to a reference moisture content of 12 %. The limits specified in this

33、standard shall apply at the time of delivery. EN 13307-1:2006 (E) 7 4.2.2 Cross-sectional dimensions Tolerances on cross sectional sizes shall be +2 mm to 1 mm on sawn sections and +0,5 mm to 0 mm on planed profiles. These tolerances apply at a moisture content of 12 %. For tolerances at other moist

34、ure contents the following formula shall apply to correct the tolerance to a 12 % value: = 1000t12w3 (1) where : is the calculated tolerance; w is the face dimension in millimetres at a moisture content of t; t is the moisture content in %. 4.2.3 Tolerances on length Specified lengths shall not have

35、 any minus tolerance. 4.2.4 Warp 4.2.4.1 General If the tolerance on warp is not specified, the following limits for warp in all classes, measured in accordance with EN 1310, shall apply. Bow, spring or twist for planed and unplaned pieces shall be limited to the following. Where twist appears to be

36、 combined with bow or spring the permissible values shall be halved. 4.2.4.2 Bow Sawn timber F = (L / 1000)2,or 2mm, whichever is the greater. Planed F = (L / 1000)2 / 2 or 1mm, whichever is the greater. Where F is the bow and L is the length of the piece, in millimetres. 4.2.4.3 Spring Sawn timber

37、V = (L / 1000) x b / 50, or 2 mm, whichever is the greater. Planed timber V = (L / 1000) x b / 100, or 1 mm, whichever is the greater. Where V is the spring, b is the width of the piece and L is the length of the piece, in millimetres. 4.2.4.4 Cup Sawn timber limited to b/100 or 1 mm, whichever is t

38、he greater, Planed timber limited to b/200 or 0,2 mm, whichever is the greater Where b is the width of the piece in millimetres. EN 13307-1:2006 (E) 8 4.3 Condition of surface Blanks and semi-finished profiles shall, according to the contract, be supplied planed or unplaned. Any defect of flatness s

39、hall be compatible with the relevant tolerances for cross-sectional dimensions. 4.4 Moisture content 4.4.1 General The moisture content of any piece or parcel shall be estimated using the method described in EN 13183-2 or EN 131833. In the event of a dispute, the method to be used shall be the metho

40、d described in EN 13183-1. NOTE The more accurate method described in EN 13183-1 is a Destructive method and may not always be appropriate. 4.4.2 Moisture content at delivery The average moisture content at delivery and permitted deviation shall be specified by the buyer. NOTE Guidance on the moistu

41、re content of timber for any particular end application is given in prCEN/TS 13307-2. 4.5 Timber quality 4.5.1 General requirements The quality of each face of a piece shall comply with the requirements of one of the classes given in prEN 942. In the event of a dispute the quality of a lot or batch

42、shall be assessed using the selection process given in ENV 12169 using an AQL of 10. 4.5.2 Growth rings The relationship between the angle of the growth rings in adjacent lamella has a significant affect on the stability and performance of the laminated profile and shall be considered by the manufac

43、turer. Advice on methods of reducing problems is given in Annex A. 4.6 End joints 4.6.1 Finger joints Finger joints in outer layers shall comply with the requirements of prEN 942. Finger joints in laminated profiles shall be permitted in inner layers. The individual parts of jointed members shall be

44、 of similar wood structure in respect to width and slope of the growth rings. A gap between the finger and root of a cut is not allowed, nor are cracks radiating from the fingers or roots of a cut permitted. Glue lines shall be uninterrupted. Where a weather tightness performance is required the fin

45、ger joint tightness test in prCEN/TS 13307-2 shall be applied to a selected sample. NOTE Finger joints may be manufactured in such a way that the fingers are visible on the broader or narrower face of the blank or the lamella. Where a wind load performance is required the distance between two adjace

46、nt finger joints shall be greater than 150 mm. EN 13307-1:2006 (E) 9 4.6.2 Butt joints Butt joints are only permitted to the inner layers of laminated profiles. A butt joint shall not occur within 150 mm of another butt joint in an adjacent lamella. 4.7 Lamination 4.7.1 Thickness of lamella There is

47、 no general limitation on the thickness of lamella. NOTE In laminated cross-sections intended for external use, the thickness of outer layer should not be less than 18 mm. For some applications (e.g. door stiles) thinner outer laminations may be acceptable. 4.7.2 Mixing of species The mixing of spec

48、ies is allowed if the following conditions are fulfilled, and proven by testing in accordance with prCEN/TS 13307-2: compatibility of bond strength; compatibility of the stability of the species. 4.7.3 Glue line bonding The thickness of the glueline shall be within the limits recommended for the typ

49、e and end use condition as specified by the adhesive manufacturer. NOTE 1 The thickness of the glueline depends on the type of glue used and the end use specification provided by the manufacturer. NOTE 2 Edge to edge gluing is not recommended in the outer layers of a glued laminated product. NOTE 3 Special care has to be taken when laminating some species, particularly with regard to density, wettability and pre-treatment processes. 5 Marking and labelling Blanks and semi-finished profiles for joinery
