ISO and IEC maintain terminological databases for use in standardization at the following addresses:
IEC Electropedia: available at http://www.electropedia.org/
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.

1 Scope
This European Standard specifies characteristics,; states requirements and gives test methods for
modular multilayer floor coverings with an surface layer based on wood powder (as defined in 3.1).
It includes a classification system, based on EN ISO 10874, giving practical requirements for areas of
use and levels of use, to indicate where powder based floor coverings will give satisfactory service and
to encourage the consumer to make an informed choice. It also specifies requirements for marking and
packaging.
Powder based floor coverings are considered for domestic and commercial levels of use.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
ISO and IEC maintain terminological databases for use in standardization at the following addresses:
• IEC Electropedia: available at http://www.electropedia.org/
• 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 may vary in thickness, format, surface texture, gloss level and colour.
3.2
wood powder based surface layer
upper decorative layer consisting of one or more powder based layers, comprising resins such as amino
plastic, thermosetting resins (usually melamine)
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 may be fitted on substrates by for example a gluing operation.
3.3
powder based layer
wood powder particles, aminoplastic powder binder, additives; pigments and any corundum is mixed
together as a dry powder composite and scattered in layers
3.4
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
3
MDF-board with a density ≥ 800 kg/m .

3.5
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.
3.6
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.

A.2 Conditioning
Test specimens are measured in the received state. For type approval or verification purposes, the test
specimens shall be stabilized to a constant mass in an atmosphere of (23 ± 2) °C and (50 ± 5) % relative
humidity. Constant mass is considered to be reached when the results of two successive weighing
operations, carried out at an interval of 24 h, do not differ by more than 0,1 % of the mass of the test
specimens.
A.3 Apparatus
A.3.1 Micrometre, calliper gauge or any other equivalent tool, having flat and parallel circular
measuring surfaces of at least 16 mm diameter and an operating force of (4 ± 1) N, with an accuracy
of ± 0,05 mm, for thickness measurements.
A.3.2 Calliper gauge or any other equivalent tools with an accuracy of ± 0,05 mm for width
measurements, and ± 0,1 mm for length measurements.
A.3.3 Square with arms of at least 300 mm and having a maximum angular deviation of 0,02 mm over
300 mm.
A.3.4 Set of thickness gauges ranging from 0,05 mm to 0,10 mm in steps of 0,01 mm, and from
0,10 mm to 0,50 mm in steps of 0,05 mm.
A.3.5 Steel ruler of length at least equal to the length of the test specimen, and having a maximum
straightness deviation of 0,05 mm over 1 000 mm.
A.3.6 Apparatus for measuring width flatness consisting of a dial gauge accurate to ± 0,01 mm with a
rounded tip of radius ≤ 5,5 mm, installed centrally in relation to three rounded supports with
radii ≥ 5 mm. The supports shall be adjustable along a T-shaped assembly of bars to provide the
required gauge length. The measurement d shall not be less than the width w of the test specimen
minus 10 mm. The tip of the gauge in contact with the face of the test specimen shall apply a force of
(1,0 ± 0,5) N. The mass of the apparatus shall not affect the flatness of the test specimen beyond the
limit of the accuracy of the gauge. See Figure A.1 for illustration. The instrument shall be set to zero
against a suitable reference plate.
