DIN EN 15468:2016-08 EN 15468:2016 (E) 4 1 Scope This European Standard specifies characteristics, states requirements and gives test methods for laminate floor coverings (as defined in 3.1). It includes a classification system, based on EN ISO 10874, providing practical requirements for
24、 areas of use and levels of use, to indicate where laminate floor coverings 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
25、 use, e.g. in domestic kitchens. This standard does not specify requirements relating 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 in

32、s For the purposes of this document, the following terms and definitions apply. NOTE This European Standard specifies characteristics, requirements and test methods for laminate floor coverings with directly applied printing and resin surface layer as defined in 3.1 and 3.2. 3.1 laminate floor cover
33、ing 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 joined together to form a larger integral unit. The product may vary in surface texture and
34、 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 resin based surface layer upper decorative layer intended to be the visible side when the floor is installed, consisting of resins (usu
35、ally acrylate, methacrylate or similar) which are cured using UV radiation or other curing methods Note 1 to entry: It can exhibit impregnated and coated materials (generally dcor paper), or at least one paint or varnish layer applied direct on the board using indirect printing, direct printing or d
36、igital printing. The combination of the multi-layered surface produced with this technique is called Printed Dcor Laminate (PDL). 3.3 substrate core material of the laminate floor covering Note 1 to entry: It is generally a particleboard, as defined in EN 309, or a Dry process fibreboard (MDF) as de
37、fined 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 generally made of impregnated papers 3.5 underlay layer placed between t
38、he 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. 3.6 laminate floor covering element piece of the floor covering with profiled edges to facilitate assembly at instal
39、lation Note 1 to entry: See Figure 1. DIN EN 15468:2016-08 EN 15468:2016 (E) 6 Key 1 surface layer 2 substrate 3 backer 4 underlay (optional) Figure 1 Laminate floor-covering element 4 Requirements 4.1 General requirements Laminate floor coverings according to this standard shall conform to the gene
40、ral requirements given in EN 13329:2016 when tested by the methods given therein. For special applications, such as decorative pattern effects, tighter tolerances might be required. The tolerances of the tongue and groove shall be such that when, for testing, the elements are assembled without glue,
41、 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 laboratory test in controlled conditions shall be made. 4.2 Classification requirements Laminate floor coverings using t
42、he PDL technologies, according to this standard, shall be classified as suitable for different levels of use according to the classification requirements specified in Table 1, when tested by the methods given therein. Classification shall conform to the scheme specified in EN ISO 10874. For the big
43、ball impact test a standard EPS foam of (1,8 0,2) mm thickness, with a CS value of (60 10) kPa and with PC-value of (0,9 0,1) mm shall be used. The three parameters of the foam shall be determined according to CEN/TS 16354.1)1) The product “Selitflex 1,6 mm” made by Selit Dmmtechnik GmbH is an examp
44、le of a suitable product available commercially. This information is given for the convenience of users of this European Standard and does not constitute an endorsement by CEN of this product. Equivalent products may be used if they can be shown to lead to the same results. DIN EN 15468:2016-08 EN 1
