EN 14221:2006 (E) 4 Introduction The classification method gi

20、ven in this standard is applicable to timber and wood-based products after it has been incorporated into internal windows, doors and doorframes. This standard contains the principle material requirements of timber in windows, internal door leaves and doorframes. This standard applies to timber and w

21、ood-based products, the processing and the components in the final products. Requirements for mechanical aspects are indirectly considered by appearance and density selection. Characteristics and principles are listed in Table 1 and clauses 5, 6, 7, 8 and 9. Specific national requirements are given

22、in Annex A. This standard includes a Normative Annex A providing guidance on National grading requirements. Tables A.1 and A.2 of Annex A provide default tables for circumstances where a National Annex is not available. This standard is part of a series of standards on timber in windows, doors and s

23、tairs. EN 14221:2006 (E) 5 1 Scope 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

24、 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 a

25、nd 5, and ENV 635-4. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies.

These definitions shall take into consideration the situation after installation of the product. Where there is a conflict between the defin

30、itions in the Standards referenced and those given below, the definitions given below shall apply. 3.1 profile planed piece of solid or glue-laminated wood, finger-jointed or not, with a cross-section complying with the window, door leaf or doorframe requirements 3.2 concealed face face of a joinery

31、 part which, after installation of the joinery is completed, is permanently concealed by other parts of the joinery product or by other parts or other elements, including materials such as veneer, plastic or metal NOTE These faces may be visible before the product is installed. 3.3 semi-concealed fa

32、ce visible face of a joinery part, which cannot be viewed when the window or door is in the closed position 3.4 visible face face of a joinery part which, after installation of the joinery is completed, is not permanently concealed or semi-concealed NOTE 1 An opaque coating system does not constitut

33、e concealment. NOTE 2 Faces which are visible only when moving parts (e.g. window casements or door leaves) are open are classified as semi-concealed. 3.5 appearance class any surface in joinery classified according to shakes, resin pockets, bark pockets, discoloration, sapwood, exposed pith, ambros

34、ia beetle damage and knots 3.6 coating system combination of coating materials, which are to be applied or have been applied to the face of a joinery part EN 14221:2006 (E) 7 4 General requirements The following requirements for the characteristics of the timber and wood-based products used in inter

35、nal windows, doors and doorframes shall apply: requirements for appearance, which are given in Clause 5; requirements for biological durability, which are given in Clause 6; requirements for physical properties, which are given in Clauses 7, 8 and 9. For products where the ultimate location is not k

36、nown at the time of manufacture, sufficient information shall be provided to enable possible limitations for the product end use to be identified. 5 Appearance 5.1 Characteristics The characteristics of the profiles that are applicable to the finished product are measured and classified in accordanc

37、e with the requirements of prEN 942. 5.2 Appearance classes 5.2.1 General Table 1 identifies the elements for which characteristics shall be assigned and is a template to indicate the form in which the requirements are to be presented. National requirements are presented in Annex A. Where national r

38、equirements have not been indicated in Annex A then the values given in Tables A.1 and A.2 are to be used. The appropriate timber classes are as specified in prEN 942.

Where specific national requirements are not available the following restrictions shall apply: Finger jointing, end jointing, edge jointing and laminating is permitted in all elements of Table 1 unless otherwise specified. In

42、fill panels produced from finger jointed pieces shall be manufactured so that when assembled only the fingers of the finger joint are visible. Finger jointing is not permitted where a translucent coating system is applied except where agreed. Laminated timber shall comply with the requirements of EN

43、 13307-1. 5.3 Adhesives and repair compounds Glued timber joints or repairs shall be of durability class D2 as specified in EN 204 or C2 as specified in EN 12765. Any glued timber joints or elements which are in a special condition of high humidity shall use an adhesive of durability not inferior to

44、 class D3 as specified in EN 204 or C3 as specified in EN 12765. At the time of publication no European tests or classifications are available for repair compounds. Repair compounds shall therefore have a similar durability class as the appropriate adhesive. NOTE Adhesives used to connect timber wit

45、h non-timber components may need special consideration. EN 14221:2006 (E) 9 5.4 Slope of grain The slope of grain of timber used shall not exceed 1:10 (10 %), except in knot areas. In addition, the cumulative length of areas with sloped grain, evaluated along the axis of the timber member, shall not

46、 exceed 0,5 m or 20 % of the length of the piece, whichever is shorter. NOTE Slope of grain may also have an effect on the stability of the product. 5.5 Repairs 5.5.1 Features Where indicated in prEN 942 the following features shall be improved, using a repair compound or wooden plugs secured with a

47、dhesive, unless specifically excluded by the specification: - Loose or unsound knots; - Shakes; - Resin pockets and other areas of resin exudation; - Bark pockets; - Exposed pith; - Ambrosia beetle attack. 5.5.2 Plugs Any plug shall: a) be of the same species or species with similar characteristics

48、as the surrounding timber; b) be secured with an appropriate adhesive (see Clause 5.3); c) whenever possible lie with its grain direction in the same general direction as the grain of the piece in which it is inserted; d) be of a width (i.e. the lesser dimension) not greater than 6 mm above the maxi

49、mum limit of knot size for the specified class (the width of a non-cylindrical plug shall be not more than 30 mm); NOTE It is possible that a plug may be produced from branch material to create the appearance of a knot. e) be within (+ 0, -2) percentage points of the moisture content of the timber; f) be within the moisture content range recommended by the adhesive manufacturer; g) have at least 2/3 of its diameter within the face when occurring at an arris. Only one plug shall be used for a single repa
