Overview

EN 622-4:2024 is a European standard published by CEN that specifies the requirements for softboards-a type of fibreboard with densities ranging from 230 kg/m³ to 400 kg/m³. These softboards are defined in EN 316 and are primarily used in various building and construction applications. The standard focuses on product properties such as swelling, bending strength, and modulus of elasticity, but clarifies these values are not intended for design calculations.

This updated 2024 edition supersedes EN 622-4:2019 and introduces revisions to load duration classifications and board type denominations. It applies across the European Economic Area (EEA) and sets out compliance and marking requirements ensuring quality and traceability.

Key Topics

  • Scope and Definitions:
    EN 622-4 covers softboards with nominal densities between 230–400 kg/m³. It excludes fibreboards solely designed for thermal insulation, which fall under EN 13171. Key terms such as dry, humid, and external conditions define the environmental suitability categories based on moisture exposure and service class.

  • Requirements:
    The standard classifies softboards into general purpose and load-bearing types, with specific property requirements for dry, humid, and external conditions. Essential measured properties include:

    • Swelling in thickness after 2 hours immersion (per EN 317)
    • Bending strength (per EN 310)
    • Modulus of elasticity in bending (for load-bearing boards, per EN 310)

    These properties vary depending on nominal thickness and intended use, ensuring the softboards can withstand expected environmental and mechanical stresses.

  • Verification and Control:
    Compliance is verified through factory production control and external inspections using established sampling and testing methods (EN 326 series). Testing intervals and sampling procedures ensure ongoing product quality during manufacturing.

  • Marking & Traceability:
    For construction market boards under the EU Construction Products Regulation, marking must meet EN 13986 requirements. Other softboards require manufacturer identification, batch numbers, nominal thickness, and board type markings. A standardized colour coding system facilitates quick identification of board type and intended usage.

Applications

EN 622-4 certified softboards are widely utilized in building and furniture manufacturing where fibreboards must meet specific performance criteria for moisture resistance and load-bearing capacity. Typical applications include:

  • Interior wall and ceiling linings
  • Flooring underlays and substrates
  • Non-load-bearing fitments
  • Load-bearing structural elements in dry or humid conditions
  • Certain external applications where moisture exposure is limited

This standard ensures the softboards perform reliably in these contexts, maintaining dimensional stability and mechanical strength to support usage over the product life cycle.

Le document standard SIST EN 622-4:2024 présente des spécifications fondamentales pour les panneaux de fibres, avec un accent particulier sur les exigences relatives aux softboards. Ce standard s'inscrit dans le cadre défini par la norme EN 316 et porte sur des panneaux ayant une densité variant de 230 kg/m3 à 400 kg/m3. L'un des points forts de ce standard réside dans sa précision et sa clarté concernant les exigences des softboards. Il offre un cadre détaillé qui permet aux fabricants et aux utilisateurs de comprendre exactement ce qui est requis en matière de qualité et de performance. Ce niveau de spécification contribue à garantir que les produits répondent aux normes de sécurité et de durabilité, éléments cruciaux dans de nombreuses applications commerciales et industrielles. De plus, la norme précise que les valeurs listées ne doivent pas être considérées comme des valeurs caractéristiques à utiliser dans les calculs de conception. Cette distinction est essentielle, car elle guide les concepteurs et les ingénieurs vers une utilisation appropriée des propriétés des produits, évitant ainsi les erreurs de conception qui pourraient compromettre la performance des projets. La pertinence de ce standard est d'autant plus renforcée par le fait qu'il s'intègre harmonieusement dans le paysage normatif existant, notamment avec des références à d'autres normes comme la EN 13171, qui traite des panneaux destinés à un usage exclusif en tant que produits isolants thermiques. Cette interconnexion des normes souligne l'importance d'adopter une approche cohérente dans l'utilisation des matériaux en fibre, contribuant à une évolutivité et une interopérabilité dans l'industrie. En somme, le SIST EN 622-4:2024 se présente comme un document standard essentiel qui fournit des directives claires et précises pour les softboards, tout en soulignant leur application et leur intégration dans des systèmes plus larges, garantissant ainsi une performance adéquate et conforme aux attentes du marché.
