Test methods for the determination of thickness, length, width, squareness, deviation from edge straightness and cup A.1 Scope This Annex specifies methods for measuring the thickness, length, width, squareness, deviation from edge straightness and cup of wood veneer floor covering elements. A.2 Sampling Take 5 elements at random. A.3 Conditioning Elements are measured without conditioning. If requested, the test pieces 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 24h, do not differ by more than 0,1 % of the mass of the test pieces. A.4 Test equipment A.4.1 Micrometer, sliding caliper or any other equivalent tool giving an accuracy of 0,05 mm. A.4.2 Sliding caliper or any other equivalent tool giving an accuracy of 0,01 mm. A.4.3 Square arms with lengths of 300 mm and having a maximum angular distortion of 0,02 mm at 300 mm. A.4.4 Steel ruler of length at least equal to the length of test specimen and having a maximum straightness deviation of 0,05 mm over 1 000 mm. A.4.5 Apparatus (T–assembly) for measuring width flatness consisting of a dial gauge accurate to ± 0,01 mm with a rounded tip with a radius of ≤ 5,5 mm, installed centrally in relation to three rounded supports with a radius of ≥ 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. SIST EN 14354:2005

A.4.7 Thickness gauges ranging from 0,5 mm to 0,10 mm in steps of 0,01, and from 0,10 mm to 0,50 mm in steps of 0,05 mm. A.5 Procedure A.5.1 Determination of thickness t
Measure the thickness t with a micrometer, or any other device of the equipment described in A.4.1, at a distance of 20 mm from the edges of the top layer, at points located in each corner and in the middle of each long side (only four corner points if the length is ≤ 600 mm), see Figure A.2. SIST EN 14354:2005

Figure A.2 — Measuring points for determination of thickness t A.5.2 Determination of length l For decorative pattern effects, measure the length of the elements with the test equipment described in A.4.2. For non decorative pattern effects, measure the length of the elements when shorter than 500 mm with the test equipment described in A.4.2 and for lengths equal to or longer than 500 mm, with the test equipment described in A.4.6. Measure the length l of the top layer along two lines parallel to the axis of the element and at a distance of 20 mm from the edges (see Figure A.3). Dimensions in millimetres
