EN 14221:2006 (E) 3 Foreword This document (EN 14221:2006) has been prepared by Technical Committee CEN/TC 175 “Round and sawn timber”, the secretariat of which is held by AFNOR. 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of an identical text or by endorsement, at the latest by May 2007, and conflicting national standards shall be withdrawn at the latest by October 2007.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
Explanation Standards 3 and 4 rely on both Standards 1 and 2, and Standard 2 relies on 1. The revised prEN 942 contains changes which directly affect Standards 2, 3 and 4 and therefore shall be available before they can be used effectively. NOTE Following the completion of the Technical Enquiry for prEN 13307-2 Timber blanks and semi-finished profiles for non-structural uses – Part 2: Production control, it has been agreed to remove this Standard form the package.
As a result of the necessary changes it has been agreed to offer prEN 13307-2 as a CEN/TS. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.



EN 14221:2006 (E) 4 Introduction The classification method given 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 wood-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 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 stairs.



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 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. 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 204, Classification of thermoplastic wood adhesives for non-structural applications EN 335-2, Durability of wood and wood-based products - Definition of use classes - Part 2: Application to solid wood EN 844-3:1995, Round and sawn timber - Terminology - Part 3: General terms relating to sawn timber prEN 942:2006, Timber in joinery

EN 14221:2006 (E) 6 3 Terms and definitions For the purposes of this document, the terms and definitions given in EN 844-3:1995, 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 appearance class any surface in joinery classified according to shakes, resin pockets, bark pockets, discoloration, sapwood, exposed pith, ambrosia 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 internal 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 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.
