EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of EN 438-3 testing. This European Standard applies to laminates less than 2 mm thin produced using the high pressure process, normally intended to be bonded to supporting substrates to produce HPL composite panels, and establishes a classification system for high pressure decorative laminates based on their performance and recommended main areas.

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 characterized by their qualities, durability and functional performance. HPL sheets are available in a wide variety of colours, patterns and surface finishes; resistant to abrasion, scratching, impact, moisture, heat and staining; and it has good hygienic and anti-static properties, easy to clean and maintain.
Two different HPL classification systems are commonly used in Europe and both are included as alternatives in this document. In this system, a letter denoting the material type is classified, followed by three index numbers denoting performance levels for abrasion resistance, impact resistance, and scratch resistance, respectively.
In addition to the abbreviation “HPL” and the number of this document, materials may be specified by numerical classification system or alphabetical classification system.
When viewed from different viewing angles, there should be no significant difference between the corresponding surface lacquer reference sample held by the supplier and the sample tested. The back side of the boards will be suitable for bonding (eg sanded). On sanded ridges, slight traces of creaking are allowed.
