CEN/TS 15717:20084 Introduction The aim of this Technical S
19、pecification is to give some principles and rules for good installation of parquet. This Technical Specification is not intended to replace the existing national guides or standards on installation or manufacturer guidelines. Its purpose is to identify a framework of good practice common to the exis
20、ting national standards and not to attribute responsibility for each stage of the work. NOTE specific national terms and definitions are included in national vocabulary. 1 Scope This Technical specification gives guidelines for installation of parquet flooring. Products which are defined in EN 13226
21、, EN 13227, EN 13228, EN 13488, EN 13489, EN 13629, and EN 14761 are concerned. This Technical specification applies for installations indoors, and does not apply to the installation of joists and sub floors. This Technical specification does not cover installations in service class 3 (see 3.4). 2 N

24、nstallation aspects of the assembly of parquet (i.e laying method, materials, requirements, etc.) 3.2 service class 1 characterized by a moisture content in the product corresponding to a temperature of 20 C and the relative humidity of the surrounding air only exceeding 65 % for a few weeks of the
25、year. 3.3 service class 2 characterized by a moisture content in the product corresponding to a temperature of 20 C and the relative humidity of the surrounding air only exceeding 85 % for a few weeks of the year. 3.4 service class 3 climatic conditions leading to a higher moisture content than in S
26、ervice class 2. 4 Exchange of information In order to install parquet in appropriate conditions, at the right time in the building process, it is essential that all parties have a clear understanding of the requirements of the project and of the implications for all concerned. To ensure that this is
27、 achieved, it is essential to have a wide consultation between all parties involved in the project, including subcontractors and material suppliers. This consultation should start early in the design stage. The consultation should go throughout the project from the design stage to the end of the bui
28、lding construction. 5 General National specifications and installation guides from the producer shall be applied, if they exist. 6 Control before installation 6.1 Storage and handling The parquet should be handled and stored according to the producers recommendation in order to maintain the technica
29、l characteristics. Parquet should be stored in a dry place (with a certain temperature). The elements should be stored and conditioned in their unopened packaging in the room in which installation is to take place (or in a room with similar climate conditions) long enough to achieve the same tempera
30、ture as the room of installation. Do not open the bundles packaging until installation commences. Open the bundles as the installation progresses. Glue and other materials shall be stored according to the producers recommendations. If no recommendation exists, glue should be stored at a minimum temp
31、erature of 15 C. CEN/TS 15717:20086 6.2 Materials and components used for installation 6.2.1 General Materials and components used for installation include parquet products, supporting components (joist, battens, wood-based panels etc.), fixation components (glue, screws, nails etc.), underlays, vap
32、our barriers, filling materials and false floors. The materials and components should comply with the technical specifications needed for the design (i.e. thickness of sub floor and parquet). 6.2.2 Parquet The properties of the wood products are defined in the product standards respectively. The woo
33、d product should have a moisture content suitable for the climate in use. In the event of persistent, prolonged extreme climatic conditions, dimensional changes and distortion may occur. The installer should check the received packages of parquet prior to installation with regard to: type, colour an
34、d pattern of the product, compared to the order; delivered quantity, compared to the order; dimensions, appearance, visible defects and possible damage, if in doubt, the moisture content of the elements, in accordance with the methods specified in the product standards. In case of dispute about the
35、conformity of the product quality and without agreement to the contrary between the parties, the customer and the supplier should perform an evaluation of conformity to EN 14762. 6.2.3 Fixation components (glue, screw, nails, etc.) Joints, such as expansion joints and joints between the parquet and
36、walls, pillars etc., should be in line with the size and geometry of the floor surface. 6.2.4 Under floor layers The appropriate underlay should be chosen according to the intended uses. Under floor layers should cover the following issues: vapour barrier A thin flexible sheet, thick enough to prote
37、ct the parquet from residual damp from below ; mass distribution; sound insulation When sound insulation is required, the underlay should be chosen in order to reach the level of insulation required for the parquet system and to maintain of this property with time. The underlay should have the appro
38、priate compressive strength. CEN/TS 15717:20087 6.3 Site conditions Parquet should be installed when all other trades have completed their work, i.e. when painting, wallpapering and tiling , are finished and the installation location has the correct relative humidity and temperature. This is a way t
39、o avoid dirt and moisture damage to the floor. The site environmental conditions should be maintained as close to end use conditions as possible during the installation and final inspection period (see clause 9). 6.4 Sub floor 6.4.1 General principles 6.4.1.1 Introduction Sub floors should be constr
40、ucted in accordance with the recommendations given in the relevant standards or national regulations. Those responsible for the design and construction of the sub floor should ensure that it meets the requirements i.e. should ensure that it has the appropriate characteristics, to allow the parquet t
41、o be installed successfully before the installer is asked to commence work. These characteristics include: Regularity (vertical deviation); Moisture content; Integrity of screeds; Cleaning. The information on moisture content of the sub floor together with guidance on damp proofing and eliminating c
42、onstruction moisture is particularly important. Some examples of sub floors are: Anhydride; Wood-based panels; Joist; Concrete screed. 6.4.1.2 Regularity of sub floors Regularity covers vertical deviations The vertical deviation of the installation surface should be determined by resting a straighte
43、dge on surface elevations and measuring the extent of the largest depression in the surface. The result of this measurement is expressed with respect to the distance between the elevations on which the straightedge rests (reference points). The tolerances for the sub floor are depending on the type
44、of parquet and the installation method. CEN/TS 15717:20088 Typical tolerances are: For two reference points 1,00 m apart, maximum permissible vertical deviation is 3 mm; For two reference points 2,00 m apart, maximum permissible vertical deviation is 5 mm; Individual sharp vertical height difference
45、s larger than 1,2 mm are not permitted. 6.4.1.3 Moisture content Before the parquet is installed, the moisture content of the sub floor should be close to the equilibrium moisture content it will have in service. Furthermore the moisture content should be measured. 6.4.1.4 Integrity of screeds The s
46、creed should not contain cracks that could decrease the technical characteristics of the product. The surface cohesion, which covers adhesive strength of the surface and the cohesiveness, should be controlled before the installation. 6.4.1.5 Cleaning The surface of the sub floor should be cleaned pr
47、ior to the installation of the parquet to ensure good adhesion when gluing, and evenness in general. 6.4.1.6 Existing floor covering If the parquet is glued to the sub floor, it should be sufficiently even and adherent. For floating and joist installation, if an existing textile floor covering is no
48、t removed, its total thickness should be less than 5 mm. 7 Installation 7.1 Glued installation (description and characteristics) Gluing of parquet elements to sub floor should be done without any gluing in interlocking system. Depending on the sub floor and glue priming might be necessary. The glue
49、chosen should give sufficient adhesion to both the parquet and the sub floor and have the ability to take up the stresses the parquet will inflict on the glue line. A gap between the parquet and the fixed installations such as walls has to be provided to allow movements of the floor. 7.2 Floating installation (description and characteristics) In a floating installation the elements are attached to each other and not to the sub floor. This can be done by gluing, mechanical or geometric jointing systems or other systems. The parque
