This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by May 2007, and conflicting national standards shall be withdrawn at the latest by October 2007. This Standard is one of a package to be implemented by 2007.10.31.
The Standards included in the Package are:
Standard Number Title 1 prEN 942 Revised Timber in joinery - General requirements 2 EN 13307-1 Timber blanks and semi-finished profiles for non-structural uses – Part 1: Requirements 3 EN 14220 Timber and wood-based materials in external windows, external door leaves and external doorframes – Requirements and specifications 4 EN 14221 Timber and wood-based materials in internal windows, internal door leaves and internal doorframes – Requirements and specifications

EN 14220:2006 (E) 4 Introduction The classification method given in this standard is applicable to timber and wood-based products after they have been incorporated into complete windows, external door leaves and external doorframes.
This standard contains the principle material requirements of timber in wood-based products, the processing of this timber 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 in Annex A. This standard contains two annexes, Annex A "National requirements" and Annex B "Weather exposed faces". 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 stairs.
EN 14220:2006 (E) 5 1 Scope 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. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

EN 14220:2006 (E) 6 3 Terms and definitions For the purposes of this document, the terms and definitions given in EN 844-3:1995 and prEN 942:2006 and the following apply. These definitions shall take into consideration the situation after installation of the product. Where there is a conflict between the definitions 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 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 face 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 constitute 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 weather exposed face face of a joinery part, which is directly subjected to driving rain or running water or permanent or intermittent condensation NOTE For examples see Annex B. 3.6 appearance class any surface in joinery classified according to shakes, resin pockets, bark pockets, discoloration, sapwood, exposed pith, ambrosia beetle damage and knots
3.7 coating system combination of coating materials, which are to be applied or have been applied to the face of a joinery part
EN 14220:2006 (E) 7 4 General requirements The following requirements for the characteristics of the timber and wood-based materials used in windows, external door leaves and external 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 known 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 accordance 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 requirements 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.

See Table A.1 for default values.
Where products are subject to wind load, consideration shall be given to the use of a higher grade. When classifying a face as concealed, the grade selected shall not impair the serviceability of the product. 5.2.2 Finger jointing, end jointing, edge jointing and laminating Specific national requirements are given in Annex A.
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.
Infill 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 13307-1. 5.3 Adhesives and repair compounds Adhesives in timber joints, profiles or repairs which are in a weather exposed position shall be of a durability not inferior to D4 as specified in EN 204 or C4 as specified in EN 12765.
Adhesives in any other joints, profiles or repairs shall be of a durability not inferior to D3 as specified in EN 204 or C3 as specified in EN 12765. If a lower class of adhesive is used its use shall be declared and justified.
EN 14220:2006 (E) 9 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 with non-timber components may need special consideration. 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 exceed 0,5m or 20 % of the length of the piece, whichever is the shorter. NOTE Slope of grain may also have an effect on the stability of the product. 5.5 Repair 5.5.1 Features Where indicated in prEN 942 the following features shall be improved, using a repair compound or wooden plugs secured with adhesive, unless specifically excluded by the specification/ - Loose or unsound knots; - Shakes; - Resin pockets and other areas of resin exudation; - Bark pockets; - Exposed pith; - Amb
