— the categories and requirements of non-planar laminate floor coverings and laminate floor coverings for ground with heating system are added (see Clauses 4, 5 and 6);
— commercial laminate floor coverings are modified to commercial levels I and II (see 4.1; 4.1 of Edition 2007);
— Classification by abrasion resistance (see 4.5 of Edition 2007) and classification by formaldehyde emission (see 4.6 of Edition 2007) are deleted;
— the requirements and inspection methods of locking force and surface resistance to water vapour are added to the requirements of planar laminate floor coverings (see 5.4.1, 6.3.15 and 6.3.18);
— the index of density, and the class and index of formaldehyde emission are modified (see 5.4.1; 5.4 of Edition 2007);
— in the provisions of planar laminate floor coverings, the thickness swelling rate of water absorption is adjusted, the performance indexes of surface bonding strength and abrasion resistance are set according to the purpose, and the corresponding indexes are modified (see 5.4.1; 5.4 of Edition 2007);
— the requirements of static bending strength of planar laminate floor coverings are deleted (see 5.4 of Edition 2007).
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. The issuing body of this document shall not be held responsible for identifying any or all such patent rights.
