BS EN 438-5:2016EN 438-5:2016 (E) 4 1 Scope This European Stand
22、ard 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 elements. For laminate floor covering applications they meet the surface property requirements specified in EN
23、 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 properties and are easy to clean and maintain. The requirements in this document apply only to the high-pressure lam
24、inate, 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 laminates as defined in Clause 3. EN 438-2 specifies the methods of test relevant to this European Standard. 2

46、. 5.2.5 Visual inspection 5.2.5.1 General The following inspection requirements are intended as a general guide, indicating the minimum acceptable quality for laminates. It should be noted that only a small percentage of sheets in a batch (the level to be agreed with the customer) should contain def
47、ects of the minimum acceptable level. 5.2.5.2 Surface quality The following surface defects are permissible: a) dirt, spots and similar surface defects. The admissible size of such defects is based on a maximum contamination area equivalent to 1,0 mm2/m2of laminate and is proportional to the sheet s
48、ize under inspection. The total admissible area of contamination may be concentrated in one spot or dispersed over an unlimited amount of smaller defects. b) fibres, hairs and scratches. The admissible size of defects is based on a maximum contamination length equivalent to 10 mm/m2of laminate and i
49、s proportional to the sheet size under inspection. The total admissible length of contamination may be concentrated in one defect or dispersed over an unlimited amount of smaller defects. 5.2.5.3 Edge quality Visual defects (e.g. moisture marks, lack of gloss, corner damage, etc.) can be present on all four edges of the laminate, providing the defect-free length and width are at least the nominal size minus 10 mm. 5.3 Dimensional tolerance requirements Dimensional tolerance requ
