Licensed Copy: Wang Bin, na, Fri Sep 15 03:38:11 BST 2006, Uncontrolled Copy, (c) BSIEN 14978:2006 (E) 4 1 Scope This European Standard specifies requirements for l
20、aminate floor coverings with an acrylic based surface layer (as defined in Clause 3). It includes a classification system based on EN 685, giving practical requirements for areas of use and levels of use, to indicate where laminate floor coverings will give satisfactory service and to encourage the
21、consumer to make an informed choice. It also specifies requirements for marking and packaging. Laminate floor coverings are considered for domestic and commercial levels of use. This standard does not specify requirements related to areas that are subjected to frequent wetting, such as bathrooms, la
22、undry rooms or saunas, but the products covered by this standard are applicable for use in domestic kitchens. 2 Normative references The following referenced documents are indispensable for the application of this document.

28、N 13329:2006 and the following apply. 3.1 laminate floor covering floor covering with a surface layer consisting of one or more thin sheets of a decorative material (usually paper), impregnated with either aminoplastic, thermosetting resins (usually melamine) or impregnated and surfaced with an acry
29、late and/or metacrylate resin NOTE 1 By the simultaneous action of heat and pressure, the sheets impregnated with aminoplastic resins are either pressed as such (HPL, CPL, Compact) and in the case of HPL and CPL bonded to a substrate (usually wood-based panels), or in the case of DPL, directly press
30、ed to a substrate (usually wood-based panels). NOTE 2 When using acrylate and/or metacrylate resins the simultaneous action of electron beams and pressure are used to produce the thin sheets, which are then bonded to a substrate (usually wood-based panels). NOTE 3 The product is usually finished wit
31、h a backing (e.g. HPL, CPL, EPL, impregnated papers and veneers) primarily used as a balancing material. 3.2 acrylic based surface layer upper decorative layer intended to be the visible side when the floor is installed NOTE This layer consists of resins which are hardened using electron beams (norm
32、ally acrylate, metacrylate or similar) and impregnated and surfaced decorative materials (normally paper), which all together are hardened through the application of a sufficient dose of electron beams and constant pressure. The surface layer produced with this technique is called Electron-beam Pres
33、sed Laminates (EPL). 4 Characteristics Laminate floor coverings according to this standard shall conform to the general requirements given in EN 13329:2006, Table 1, with the following modifications: for special applications, such as decorative pattern effects, tighter tolerances shall be permitted
34、if necessary; tolerances of the tongue and groove shall be such that when, for the purposes of testing, the elements are assembled without glue, the maximum permissible opening and height difference values are not exceeded; to determine the capability of laminate floor coverings to withstand ambient
35、 humidity variations, a laboratory test in controlled conditions shall be made.

36、e two specular gloss-levels of the surface layer shall be done prior to classification testing. The specular gloss level shall be determined following testing in accordance with EN ISO 2813 with a detection angle of 60 . The distinction between the two specular gloss levels shall be as follows: comm
37、on gloss level specular gloss level 85 units high gloss level specular gloss level 85 units 5.2 Floor coverings with a common gloss level Laminate floor coverings conforming to this standard with a common gloss level as described in 5.1, shall be classified as being suitable for different levels of
38、use according to the requirements specified in EN 13329:2006, Table 2, when tested by the methods given therein. Classification shall conform to the scheme specified in EN 685. 5.3 Floor coverings with a high gloss level Laminate floor coverings conforming to this standard, with a high gloss level a
39、s described in 5.1, shall be classified as being suitable for different levels of use according to the requirements specified in Table 1, when tested by the methods given therein.
