4 Test pieces
The test pieces for the following tests shall be taken at least 150 mm from the edge of the product.
When needed, the longitudinal or transverse direction of the decorative surface shall be specified by the
manufacturer for the tests on the products.
5 Conditioning of test pieces
Unless specified otherwise for the individual tests, the test pieces shall be tested in the received state.
In cases of dispute or for type approval, the test pieces shall be conditioned for one week in an
atmosphere of (23 ± 2) °C and (50 ± 5) % relative humidity prior to testing.
6 Test methods
6.1 Dimensions (thickness, length and width)
These properties shall be determined in accordance with EN 324-1.
6.2 Flatness
6.2.1 Principle
Flatness is determined by measuring the maximal deviation of the board surface from a metal straight
edge placed at two selected positions parallel to the long and short edges of the board or panel.
6.2.2 Apparatus
Straight edge, of (1 000 ± 1) mm length, with dial indicator gauge (comparator) graduated to permit a
reading accuracy of 0,1 mm.
6.2.3 Test pieces
The test piece shall be the complete board under test, as received, stored in the conditions
recommended by the manufacturer.
6.2.4 Procedure
Place the board in a vertical position free from restraint with one long edge resting on an essentially
horizontal floor. Place the flatness gauge on the concave surface at various positions. At each position,
measure the greatest distance between board surface and the flatness gauge with an accuracy of
0,1 mm.
6.2.5 Expression of results
The result of the test is the highest recorded reading on the dial gauge in millimetres to the nearest
0,1 mm.
6.3 Edge damage
6.3.1 Principle
Edge damage is determined by placing a graduated mask or tape measure on the board or panel under
test and measuring the size of chips of paper removed from the edges.
6.3.2 Apparatus
A metal tape measure or mask graduated in divisions of 1 mm.
6.3.3 Test pieces
The test piece is the board or panel as received.
6.3.4 Procedure
The test piece is laid level on a protective surface. Loose surface contamination is to be removed using a
soft brush. Using the metal tape measure or the mask the size of the chip is measured at right angles to
the board edge, across the chip towards the centre of the board.
6.3.5 Expression of results
Record the dimensions of the largest chip of paper removed to the nearest millimetre (mm).
6.4 Surface defects
6.4.1 Principle
Inspection of boards for surface appearance under standardized conditions of lighting and viewing.
Surface defects are > 0,8 mm and those that are identified when the surface texture is viewed from a
distance of 0,7 m and at an angle about of 45°.
6.4.2 Apparatus
The light source shall provide a diffused illumination of (1 200 ± 400) lx over the whole area. This shall
either be diffused daylight or be diffused artificial light. The daylight shall be unaffected by surrounding
trees, etc. When artificial daylight is used, it shall have a correlated colour temperature of (5 000 to
6 500) K and a Ra > 92, by using a colour matching booth in accordance with EN ISO 3668.
A convenient distance of the lights from the inspection table is approximately 1,5 m.
6.4.3 Test pieces
The test piece shall be the board under test, as received.
6.4.4 Procedure
Place the board, decorative face uppermost, on the inspection table and wipe it free of any loose
contamination, if necessary, with a soft cloth and any suitable cleaning agent if necessary. Inspect it
from the distance required (specified in 6.4.1) for defects such as smudges, smears, finger-prints,
scratches, foreign particles, damage or any other form of blemish evident within the decorative surface.
In case of cut to size panels the inspection shall be performed on the edges too.
The evaluation of the total area of spot-type defects in square millimetres and of the total length of hair-
like defects in millimetres shall be carried out with the help of a Size Estimation Chart . In case of
dispute the inspection shall be carried out by three observers using a Chart.
The tester shall have normal eyesight, corrected if necessary No magnifying glass shall be used in
viewing the sheet. In cases of doubt or dispute, three observers are required for the visual assessment.
All observers shall not have any colour perception impediment. In case of three observers, the reported
rating for the test surface shall be the average to the nearest nomin
