DIN EN 438-5:2016-06 EN 438-5:2016 (E) 4 1 Scope This European Standard applies to six classes of flooring grade laminates less than 2 mm thick produced by using a high pressure process, intended for bonding to supporting substrates, to produce HPL flooring el
29、ements. For laminate floor covering applications they meet the surface property requirements specified in EN 13329. High-pressure decorative flooring laminates are characterised by their high resistance to abrasion, aesthetic qualities and durability. They have good hygienic and anti-static properti
30、es and are easy to clean and maintain. The requirements in this document apply only to the high-pressure laminate, and additional properties will need to be specified in order to define the functional performance of the finished flooring product. This European Standard applies only to decorative lam
31、inates as defined in Clause 3. EN 438-2 specifies the methods of test relevant to this European Standard. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

39、re of 5 MPa. 3.1.2 surface layer upper decorative layer consisting in one or more sheets of fibrous material (usually paper) impregnated with aminoplastic thermosetting resins (usually melamine based resins) Note 1 to entry: The surface layer(s) on one side, having decorative colours or designs, are
40、 impregnated typically with melamine based resins and may contain special surface additives to improve abrasion resistance. Note 2 to entry: The back of the sheet(s) is made suitable for adhesive bonding to a substrate. 3.1.3 core layer fibrous material (usually paper) impregnated with thermosetting
41、 resins (usually phenolic based resins) 3.2 Symbols For the purpose of this document, the following symbol applies. t nominal thickness 4 Classification system The classification system makes reference to EN ISO 10874 (level of use) in combination with the abrasion class (AC) given by a numerical ra
