High-pressure decorative (HPL) - Sheets based on thermosetting resins (Usually called Laminates) - Part 6: Classification and specifications for exterior-grade compact laminates of thickness 2 mm and greater

This European Standard applies to Exterior-grade Compact laminates of thickness 2 mm and greater produced by using a high pressure process. It specifies requirements for standard and flame-retardant laminates intended for use under outdoor weather conditions such as direct sunlight rain and frost. Two levels of performance are specified; one for moderate exterior conditions, and the other for severe exterior conditions.
Laminates complying with this European Standard are referred to as Exterior-grade Compact laminates, and are characterized by their high tensile strength, high impact resistance, thermal shock resistance, and resistance to weather and corrosion. They are available in a variety of decorative colours, with high resistance to colour change and aging in outdoor applications. When they are self-supporting Exterior-grade Compact laminates are ready for installation, and only require cutting to size, drilling, etc. to suit the application. EN 438-2 specifies the methods of test relevant to this part of EN 438.

Dekorative Hochdruck-Schichtpressstoffplatten (HPL) - Platten auf Basis härtbarer Harze (Schichtpressstoffe) - Teil 6: Klassifizierung und Spezifikationen für Kompakt-Schichtpressstoffe für die Anwendung im Freien mit einer Dicke von 2 mm und größer

Diese Europäische Norm gilt für Kompakt Schichtpressstoffe für die Anwendung im Freien mit einer Dicke von 2 mm und größer, die mit einem Hochdruckverfahren hergestellt wurden. Die Norm legt die An¬for¬de-rungen an Standardqualität und flammenhemmende Schichtpressstoffe zur Anwendung unter Witterungs-bedingungen im Freien, wie direktes Sonnenlicht, Regen und Frost, fest. Zwei Leistungsqualitäten wer¬den festgelegt; eine für mäßige Beanspruchungen und die andere für starke Beanspruchungen im Außenbereich.
Schicht¬pressstoffe, die dieser Europäischen Norm entsprechen, werden als Außen-Kompakt-Schicht¬press-stoffe (en: Exterior Grade Compact Laminates) bezeichnet und sind charakterisiert durch hohe Zug-festigkeit, hohe Sto߬festigkeit, Beständigkeit gegen schnelle Temperaturwechsel und die Beständigkeit gegen Witterung und Korrosion. Sie sind in einer Vielzahl dekorativer Farben mit einer hohen Beständigkeit gegen Farb¬ver¬änderungen und Alterung bei Anwendungen im Freien erhältlich. Selbsttragende Außen-Kompakt-Schicht¬press¬¬stoffe sind verlegefertig vorgerichtet, so dass es bei der vorgesehenen Anwendung nur erforderlich ist, sie zu¬zu¬schneiden, zu bohren usw. Die für diesen Teil von EN 438 zutreffenden Prüf¬ver¬fahren sind in EN 438-2 festgelegt.

Stratifiés décoratifs haute pression (HPL) - Plaques à base de résines thermodurcissables (communément appelées stratifiés) - Partie 6: Classification et spécifications des stratifiés compacts pour usage en extérieur d'épaisseur égale ou supérieure à 2 mm

La présente Norme européenne s’applique stratifiés compacts pour usage en extérieur d’épaisseur égale ou supérieure à 2 mm produits en utilisant un procédé haute pression. Elle spécifie les exigences pour les stratifiés standard et avec retardateurs de flamme destinés à être exposés à des conditions atmosphériques extérieures tels que le rayonnement solaire direct, la pluie et le gel. Deux niveaux de performance sont spécifiés, l’un pour les conditions extérieures modérées et l’autre pour des conditions extérieures rigoureuses.
Les stratifiés conformes à la présente Norme européenne sont désignés comme des stratifiés compacts pour usage en extérieur et se caractérisent par leur résistance élevée à la traction leur résistance élevée au choc, leur résistance au choc thermique et leur résistance aux intempéries et à la corrosion. Ils sont disponibles en diverses couleurs décoratives et présentent une résistance élevée à la décoloration et au vieillissement dans les applications à l’extérieur. Lorsqu’ils sont autoporteurs, les stratifiés compacts pour usage en extérieur sont prêts à être mis en oeuvre et n’ont plus qu’à être découpés, percés, etc., en fonction de leur utilisation. L’EN 438-2 spécifie les méthodes d’essai correspondant à la présente partie de l’EN 438.

Dekorativni visokotlačni laminati (HPL) - Plošče na osnovi duromernih smol - 6. del: Razvrstitev in specifikacije za 2 mm in več debele laminate za zunanjo uporabo

Ta del standarda EN 438 se uporablja za kompaktne laminate za zunanjo uporabo z debelino vsaj 2 mm, ki so izdelani z visokotlačnim postopkom. Določa zahteve za standardne in negorljive laminate, namenjene za uporabo pri zunanjih vremenskih pogojih, kot je neposredna sončna svetloba, dež ali zmrzal. Določeni sta dve ravni učinkovitosti: prva za zmerne zunanje pogoje in druga za izredne zunanje pogoje. Laminati v skladu s tem delom standarda EN 438 se imenujejo kompaktni laminati za zunanjo uporabo, zanje pa so značilni izredna natezna trdnost, izredna odpornost proti udarcem, odpornost na toplotne udare ter odpornost na vremenske pogoje in korozijo. Na voljo so v številnih dekorativnih barvah z izredno odpornostjo na spremembe barve in obrabo pri uporabi na prostem. Samonosilni kompaktni laminati za zunanjo uporabo so pripravljeni za namestitev in zahtevajo zgolj obrezovanje, vrtanje itd. v skladu z načinom uporabe. EN 438-2 določa preskusne metode, ustrezne za ta del standarda EN 438.

Overview

EN 438-6:2016 specifies classification and performance requirements for Exterior-grade Compact high‑pressure laminates (HPL) of nominal thickness 2 mm and greater. It applies to standard and flame‑retardant compact laminates manufactured by a high‑pressure process and intended for outdoor exposure (sunlight, rain, frost). The standard defines two performance levels - moderate and severe exterior conditions - and sets inspection, dimensional, mechanical and weathering criteria for sheets that can be self‑supporting and ready for installation.

Key topics and technical requirements

• Classification: Three‑letter system: first letter E (exterior), second G (moderate) or D (severe), third S (standard) or F (flame‑retardant) - e.g., EDF = exterior, severe, flame‑retardant.
• Test methods referenced: EN 438-2 (determination of properties), EN 13722 (gloss), EN ISO 178 (flexural tests), EN ISO 1183-1 (density), EN ISO 11664-2 (illuminants), EN 13501-1 (fire classification).
• Visual & surface inspection: Colour and pattern assessed under daylight (D65) and illuminant A; gloss tolerances specified in gloss units (GU):

  • 70 GU: ±15 GU

  • 30–70 GU: ±10 GU
  • 10–30 GU: ±5 GU
  • <10 GU: ±3 GU
• Dimensional tolerances: Thickness tolerances depend on nominal thickness (t); tolerances increase with thicker sheets (for the thinnest range the tolerance is about ±0.20 mm, rising for larger t). Flatness, edge straightness and squareness tolerances are defined; edge chipping up to 3 mm is permissible.
• Mechanical and physical properties: Minimum performance thresholds include flexural modulus (9 000 MPa), flexural strength (80 MPa), and minimum density (~1.35 g/cm3). Impact (large‑diameter ball) and resistance to wet conditions (mass increase limits and surface/edge ratings) are specified.
• Weathering & UV resistance: Separate requirements for moderate (G) and severe (D) grades. Climatic shock, UV and artificial weathering tests set minimum appearance/grey‑scale and retention indices (severe grades require higher exposure and better retention).

Applications and users

• Typical applications: external cladding, façades, balconies, kiosks, signage, shelters, exterior furniture and other outdoor architectural elements where high tensile strength, impact resistance, thermal‑shock resistance and weather durability are required.
• Primary users: architects, specifiers, façade engineers, HPL manufacturers, fabricators, building product certifiers and procurement teams who need to select, test or certify exterior HPL panels for construction projects.
