14、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of an identical text or by endorsement, at the latest by May 2007, and conflicting national standards shall be withdrawn at the latest by October 2007.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 t
15、o 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 i

17、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-
18、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
19、 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, S
20、weden, Switzerland and United Kingdom. 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 p
21、rinciple 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
22、 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 standa
23、rd 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),
24、 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
25、 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 th

These definitions shall take into consideration the situation after installation of the product. Where there is a conflict between th
33、e 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
34、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-conc
35、ealed 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
36、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 c
37、ondensation 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 h
38、ave 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
39、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
40、 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
41、 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 a
42、re to be used. The appropriate timber classes are as specified in prEN 942.

When classifying a face as concealed, the grade selected shall not impair the serviceability of the product. 5.2.2 Finger jointing, end jointing
45、, 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 spe
46、cified. 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 requirem
47、ents 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 b
48、e 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 com
49、pounds 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 m
