DIN EN 438-3:2016-06 EN 438-3:2016 (E) 4 1 Scope This European Standard applies to laminates less than 2
28、 mm thick produced by using an high pressure process, normally intended for bonding to supporting substrates to produce HPL composite panels and establishes a classification system for high-pressure decorative laminates according to their performance and main recommended fields of application, inclu
29、ding materials with special characteristics, for example formability or defined reaction to fire. This European Standard also specifies requirements for the properties of the various types of laminates covered by this classification system. High-pressure decorative laminates are characterised by the
30、ir qualities, durability and functional performance. HPL sheets are available in a wide variety of colours, patterns and surface finishes; they are resistant to wear, scratching, impact, moisture, heat and staining; and possess good hygienic and anti-static properties, being easy to clean and mainta

Type F - Decorative laminates with improved fire retardance; similar to types S or P but also meeting special requirements of specified fire tests which may vary according to the application (e.g. construction, marine, transport) and the country of use (see 6.4.
40、3 and Annex A). 5 Requirements 5.1 General Two different HPL classification systems are commonly used in Europe, and both have been included in this document as alternatives. 5.2 Numerical classification system In this system the classification of a letter denoting material type (see Clause 4) follo
