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

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
