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.
