13、echnical 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
14、 be withdrawn at the latest by September 2017.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
15、to CEN by the European Commission and the European Free Trade Association. This document supersedes EN 14322:2004. Compared to EN 14322:2004 the following modifications have been made: a) extension of the scope to extruded particleboards and sandwich boards for furniture; b) classification by resist
16、ance to abrasion only linked to initial wear point; c) deletion of resistance to cigarette burns in Table A.1;and addition of resistance to axial withdrawal of screws; d) modification in Annex B for formaldehyde release with replacement of EN 717-2 by EN ISO 12460-3. According to the CEN-CENELEC Int
17、ernal 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,

BS EN 14322:2017EN 14322:2017 (E) 4 1 Scope This European Standard specifies the surface requirements and dimen
19、sional tolerances for decorative melamine faced boards for interior use which are common for particleboards, extruded particleboards fibreboards and sandwich boards for furniture. This standard does not apply to boards laminated with so called priming foils or finish foils and laminates according to
20、 EN 438-1. This standard does not apply to laminate floor coverings. Melamine faced wood-based boards in accordance with this standard may be referred to as MFB. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for
21、 its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

NOTE 4 Numerous factors including changes in temperature and relative humidity in storage and fabrication areas at building sites may cause boards and panels to bow or twist irreversibly. 5 Appearance 5.1 Colou
31、r matching Where colour matching is required by the purchaser there shall be only slight deviation (rating 4) between the reference sample and test piece under examination when inspected according to test method given in EN 14323. For mother of pearl and metallic finishes a rating 3 is permitted. BS
32、 EN 14322:2017EN 14322:2017 (E) 6 Since slight variations in colour will occur due to inherent variation in the surfacing papers and the core board, it is recommended that boards or panels to be used side by side should be selected from the same production batch where possible and matched to ensure
33、colour compatibility before fabrication or installation. 5.2 Surface texture Where matching of surface texture is required by purchaser there shall be only slight deviation (rating 4) between the reference sample and test piece under examination when inspected according to test method given in EN 14
