DIN EN 14978:2016-08EN 14978:2016 (E) 4 1 Scope This European Standard specifies characteristics, requirements and test methods for laminate
23、 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 coverings will give satisfactory service and
24、 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 requirements related to areas that are
25、 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.

32、al 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 layer intended to be the visible side
33、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 dose of electron beams and constant
34、 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 entry: It is generally a particleboa
35、rd, 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. 3.4 backer layer opposite to the surface layer used to balance and stabilize the product Note 1 to entry: The backer is general
36、ly 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.
