BS EN 14978:2016EN 14978:2016 (E) 4 1 Scope This European Standard specifies characteristics, req
19、uirements and test methods for laminate floor coverings with acrylic based surface layer, electron beam cured as defined in 3.1 and 3.2. It includes a classification system based on EN ISO 10874, giving practical requirements for areas of use and levels of use, to indicate where laminate floor cover
20、ings will give satisfactory service and to encourage the 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, e.g. for use in domestic kitchens. This standard does not specify
21、 requirements related to areas that are subject to frequent wetting, such as bathrooms, laundry rooms or saunas. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

27、nd definitions given in EN 13329:2016 and the following apply. 3.1 laminate floor covering rigid floor covering, typically in a plank or tile format, with a multiple layer structure: e.g. backer, substrate and dcor Note 1 to entry: The planks/tiles have worked edges that allow the product to be join
28、ed together to form a larger integral unit. The product may vary in surface texture and gloss level. Note 2 to entry: Laminate flooring does not include products having a resilient, stone, textile, wood, leather or metal top surfacing material(s). 3.2 acrylic based surface layer upper decorative lay
29、er intended to be the visible side when the floor is installed consisting of resins which are hardened using beams (normally acrylate, methacrylate or similar) and impregnated and surfaced decorative materials (normally paper), which all together are hardened through the application of a sufficient
30、dose of electron beams and constant pressure Note 1 to entry: The surface layer produced with this technique is called electron-beam pressed laminate (EPL). The surface layer is bonded to a substrate (usually a wood-based panel). 3.3 substrate core material of the laminate floor covering Note 1 to e
31、ntry: It is generally a particleboard, as defined in EN 309, or a dry process fibreboard (MDF) as defined in EN 316 or a so called High Density Fibreboard (HDF) which is a MDF-board with a density 800 kg/m3. 3.4backer layer opposite to the surface layer used to balance and stabilize the product Note
32、 1 to entry: The backer is generally made of impregnated papers. 3.5 underlay layer placed between the laminate floor covering and the subfloor to impart specific properties Note 1 to entry: Some laminate floor covering products have the underlay pre-attached directly to the backer.

34、racteristics Laminate floor coverings according to this standard shall conform to the general requirements given in EN 13329:2016, Table 1, with the following modifications: For special applications, such as decorative pattern effects, tighter tolerances shall be permitted if necessary. Tolerances o
35、f 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 humidity variations, a la
36、boratory test in controlled conditions shall be made. 5 Classification 5.1 General Prior to classification testing, the specular gloss level of the laminate floor covering shall be determined in accordance with EN ISO 2813, with a detection angle of 60. A distinction shall be made between two specul
37、ar gloss levels of the surface layer: common 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 shall be classified as being suitable
38、 for different levels of use according to the requirements specified in EN 13329:2016, Table 2, when tested by the methods given therein.
