3 Terms and definitions
For the purposes of this document, the following terms and definitions 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, décor and worked edges that allow the product to be joined together to form a larger integral
unit
Note 1 to entry: Laminate flooring does not include products having a resilient, stone, textile, wood, leather or
metal top surfacing material(s).
3.2
surface layer based on aminoplastic thermosetting resins
upper decorative layer, which may vary in surface texture and gloss level, consisting of one or more thin
sheets of a fibrous material (usually paper), impregnated with aminoplastic, thermosetting resins
(usually melamine)
Note 1 to entry: By the simultaneous action of heat and pressure, these sheets are either pressed as such (HPL,
CPL, Compact), and in the case of HPL and CPL bonded on a substrate (usually wood-based panels), or in the case
of DPL directly pressed on a substrate (usually wood-based panels). The product is usually finished with a backer
(e.g. HPL, CPL, impregnated papers), primarily used as a balancing material.
3.3
substrate
#core material of the laminate floor covering containing wood for at least 65 % in mass$
Note 1 to entry: 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/m .
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 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.
3.6
laminate floor covering element
piece of the floor covering with profiled edges to facilitate assembly at installation
Note 1 to entry: See Figure 1.

A.4 Procedure
A.4.1 Determination of thickness (t)
A.4.1.1 Determination of thickness (t) of an element without pre-attached underlay
Using the micrometre, calliper gauge or any other equivalent tool, measure the thickness t at a distance
of 20 mm from the edges of the surface layer, at points located in each corner and in the middle of each
long side (only four corner points if length < 600 mm) (see Figure A.3).
Dimensions in millimetres

A.4.1.2 Determination of thickness (t) of an element with pre-attached underlay
Take one laminate floor-covering element. Take from this element three test specimens measuring
approximately 100 mm x 100 mm, two centred 10 mm in from the short edges and one exactly in the
centre of the element (see Figure A.4).
If the elements measure less than 100 mm, cut a square sample with the actual width of the element.
Measure in the middle of each sample with an apparatus according to A.3.7 (see Figure A.2) and
calculate the average of the three samples.

A.4.2 Determination of length (l)
Using the appropriate calliper gauge or any other equivalent tool, measure the length l of the surface
layer along two lines parallel to the axis of the test specimen, at a distance of 20 mm from the long sides
(see Figure A.5).

A.4.3 Determination of width (w)
Using the appropriate calliper gauge or any other equivalent tool, measure the width w, along two lines
parallel to the sides of the surface layer, at a distance of 20 mm from the sides, and in the middle for
elements with a length greater than 600 mm (see Figure A.6).
