High-pressure decorative laminates (HPL) - Sheets based on thermosetting resins (usually called laminates) - Part 4: Classification and specifications for compact laminates of thickness 2 mm and greater

This European Standard specifies performance requirements for two types of compact laminate of thickness 2 mm or greater produced by using a high pressure process intended for interior use .
High-pressure decorative Compact laminates are characterised by their aesthetic qualities, strength, durability and functional performance. Compact HPL sheets are available in a wide variety of colours, patterns and surface finishes; they are extremely strong, and resistant to wear, impact, scratching, moisture, heat and staining; and possess good hygienic and anti-static properties, being easy to clean and maintain.
EN 438-2 specifies the methods of test relevant to this European Standard.

Dekorative Hochdruck-Schichtpressstoffplatten (HPL) - Platten auf Basis härtbarer Harze (Schichtpressstoffe) - Teil 4: Klassifizierung und Spezifikationen für Kompakt-Schichtpressstoffe mit einer Dicke von 2 mm und größer

Diese Europäische Norm legt die Leistungsanforderungen für zwei Kompakt Schichtpressstofftypen mit einer Dicke von 2 mm oder größer fest, die für die Innenanwendung vorgesehen sind.
Die dekorativen Hochdruck Kompakt-Schichtpressstoffe sind charakterisiert durch ihre ästhetische Beschaf¬fenheit, ihre Festigkeit, Dauergebrauchstauglichkeit und Beanspruchungsfähigkeit. Kompakt-HPL-Platten sind in einer Vielzahl von Farben, Dekoren und Oberflächenausführungen verfügbar; sie sind äußerst robust und widerstandsfähig gegen Abrieb, Stoß, Verkratzen, Feuchtigkeit, Hitze und Fleckenbildung; sie besitzen gute hygienische und antistatische Eigenschaften und sind leicht zu reinigen und zu pflegen.
Die für diese Europäische Norm zutreffenden Prüfverfahren sind in EN 438-2 festgelegt.

Stratifiés décoratifs haute pression (HPL) - Plaques à base de résines thermodurcissables (communément appelées stratifiés) - Partie 4: Classification et spécifications des stratifiés compacts d'épaisseur égale ou supérieure à 2 mm

La présente Norme européenne spécifie les exigences de performance de deux types de stratifiés compacts d’épaisseur égale ou supérieure à 2 mm produits en utilisant un procédé haute pression destinés à être utilisés à l’intérieur.
Les stratifiés décoratifs haute pression compacts se caractérisent par leurs qualités esthétiques, leur résistance, leur durabilité et leur performance fonctionnelle. Les stratifiés HPL compacts sont disponibles dans une grande diversité de couleurs, motifs et finitions de surface ; ils sont extrêmement robustes et résistants à l'usure, au choc, à la rayure, à l'humidité, à la chaleur et aux taches et possèdent de bonnes caractéristiques hygiéniques et antistatiques, tout en étant faciles à nettoyer et à entretenir.
L’EN 438-2 spécifie les méthodes d’essai correspondant à la présente Norme européenne.
