EN 14323:2017 4 European foreword This document (EN 14323:2017) has been prepared by Technical Committee CEN/TC 112 “Wood-based panels”, the secretariat of which is held by DIN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by September 2017, and conflicting national standards shall be withdrawn at the latest by September 2017. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN shall not be held responsible for identifying any or all such patent rights. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association. This document supersedes EN 14323:2004. Compared to EN 14323:2004 the following modifications have been made: a) reference to new EN 438-2:2016; b) change for light source in 5.4.2 and 5.6.3; c) to principle of resistance to scratching in 5.5.1; d) deletion of wear point for resistance to abrasion in 5.9; e) deletion of resistance to cigarette burn in 5.10. According to the CEN-CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom. SIST EN 14323:2017

EN 14323:2017 5 1 Scope This European Standard specifies test methods for the determination of characteristics of melamine faced boards (MFB) as defined in EN 14322. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 324-1, Wood-based panels — Determination of dimensions of boards — Part 1: Determination of thickness, width and length EN 438-2:2016, High-pressure decorative laminates (HPL) — Sheets based on thermosetting resins (usually called laminates) — Part 2: Determination of properties EN ISO 2813, Paints and varnishes — Determination of gloss value at 20°, 60° and 85° (ISO 2813) EN ISO 3668, Paints and varnishes — Visual comparison of the colour of paints (ISO 3668) EN ISO 4892-2:2013, Plastics — Methods of exposure to laboratory light sources — Part 2: Xenon-arc lamps (ISO 4892-2:2013) ISO 9352, Plastics — Determination of resistance to wear by abrasive wheels 3 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. 4 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 in an atmosphere of (23 ± 2) °C and (50 ± 5) % relative humidity to constant mass prior to testing. 5 Test methods 5.1 Dimensions (thickness, length and width) These properties shall be determined in accordance with EN 324-1. 5.2 Flatness 5.2.1 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. 5.2.2 Apparatus Straight edge, of (1 000 ± 1) mm length, with dial indicator gauge (comparator) graduated to permit a reading accuracy of 0,1 mm. SIST EN 14323:2017

EN 14323:2017 6 5.2.3 Test pieces The test piece shall be the complete board under test, as received, stored in the conditions recommended by the manufacturer. 5.2.4 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. 5.2.5 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. 5.3 Edge damage 5.3.1 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. 5.3.2 Apparatus A metal tape measure or mask graduated in divisions of 1 mm. 5.3.3 Test pieces The test piece is the board or panel as received. 5.3.4 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. 5.3.5 Expression of results Record the dimensions of the largest chip of paper removed to the nearest millimetre (mm). 5.4 Surface defects 5.4.1 Principle Inspection of boards for surface appearance under standardized conditions of lighting and viewing. Surface defects are larger than 0,8 mm2 and those that can be identified when the surface texture is viewed from a distance of 0,7 m and at an angle about of 45°. 5.4.2 Apparatus The light source shall provide a diffused illumination of (1 200 ± 400) lx over the whole area. This may either be diffused daylight or be diffused artificial light
