ISO Online browsing platform: available at http://www.iso.org/obp 3.1 modular multilayer floor covering floor covering, typically in a plank or tile format, having a multiple layer product structure: e.g. backer, substrate and surface layer 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 can vary in thickness, format, surface texture, gloss level and colour. 3.2 modular multilayer floor covering with wood powder based surface layer upper decorative layer consisting of one or more wood powder based layers which consists of a minimum 20% w/w of wood particles, together with aminoplastic, thermosetting resins (usually melamine), additives, pigments and any corundum and these components are dry mixed and scattered in layers on the substrate Note 1 to entry: By the simultaneous action of heat and pressure, these powder layers are either pressed as such or are directly pressed on a substrate (usually wood-based panels). The product is usually fitted with a backer (powder backer or impregnated papers), primarily used as a balancing material. In case of individually pressed layers, such layers can be fitted on substrates by, for example, a gluing operation. 3.3 substrate core material of the powder based floor covering Note 1 to entry: It is generally a particleboard, as defined in EN 309, or a Plywood board or an OSB board or a Medium Density 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 stabilise the product Note 1 to entry: The backer is generally made of wood powder or impregnated papers. 3.5 underlay layer placed between the powder based floor covering and the subfloor to impart specific properties Note 1 to entry: Some powder based floor covering products have the underlay pre-attached directly to the backer.
