22、m. DIN EN 14322:2017-07 EN 14322:2017 (E) 4 1 Scope This European Standard specifies the surface requirements and dimensional tolerances for decorative melamine faced boards for interior use which are common for particleboards, extruded particleboards fibreboards and sandwich boards for furniture. T
23、his standard does not apply to boards laminated with so called priming foils or finish foils and laminates according to 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 referen

NOTE 2 Normally, unless otherwise specified, the particleboard grade used will be as required in EN 312 (P2), the MDF grade will be as d
33、escribed in EN 6225 (MDF) and the hardboard grade will be as described in EN 6222 (HB) the extruded particleboards will be as described in EN 14755. NOTE 3 On request of the customer other values can be specified. NOTE 4 Numerous factors including changes in temperature and relative humidity in stor
34、age and fabrication areas at building sites may cause boards and panels to bow or twist irreversibly. 5 Appearance 5.1 Colour 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
35、 inspected according to test method given in EN 14323. For mother of pearl and metallic finishes a rating 3 is permitted. DIN EN 14322:2017-07 EN 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
36、 boards or panels to be used side by side should be selected from the same production batch where possible and matched to ensure colour compatibility before fabrication or installation. 5.2 Surface texture Where matching of surface texture is required by purchaser there shall be only slight deviatio
