Classification of thermoplastic wood adhesives for non-structural applications

This European Standard classifies thermoplastic resin based wood adhesives for non-structural applications into durability classes D1 to D4 based on the dry and wet strengths of bond-lines measured under specified conditions after various conditioning treatments.
For special applications, further tests that do not fall within the scope of this European standard can be applicable.
The adhesives specified in this European standard are suitable for the bonding of furniture and interior structures, panelling, doors, windows, stairs etc. made of wood or derived timber products.
This European Standard does not specify the temperature resistance of bond-lines.

Klassifizierung von thermoplastischen Holzklebstoffen für nicht tragende Anwendungen

Diese Europäische Norm stellt ein Klassifizierungssystem für thermoplastische Holzklebstoffe für nichttragende Anwendungen auf. Die Klassifizierung in die Beanspruchungsgruppen D1 bis D4 erfolgt auf der Grundlage von Messungen der Festigkeit von Klebstofffugen im nassen und trockenen Zustand unter festgelegten Bedingungen im Anschluss an unterschiedliche Lagerungsfolgen.
Für spezielle Anwendungen können weitere Prüfungen erforderlich sein, die nicht in den Anwendungsbereich dieser Norm fallen.
Die in dieser Norm behandelten Klebstoffe können für das Verkleben von Möbeln und im Innenausbau sowie bei Bekleidungen, Türen, Fenstern, Treppen usw. angewendet werden, wenn diese aus Holz oder Holzprodukten bestehen.
Die Temperatur-Beständigkeit von Klebstofffugen wird in dieser Europäischen Norm nicht behandelt.

Classification des colles thermoplastiques pour bois à usages non structuraux

La présente Norme européenne spécifie une classification des colles à bois à résine thermoplastique destinées à des usages non structuraux ; ces colles sont réparties dans les classes de sollicitation D1 à D4, en fonction de la résistance à sec et de la résistance à l'état humide des joints de colle mesurées dans des conditions spécifiées, après différents traitements de conditionnement.
Pour certaines utilisations particulières, des essais complémentaires ne relevant pas du domaine d’application de la présente Norme européenne peuvent être applicables.
Les colles spécifiées dans la présente Norme européenne conviennent pour le collage de meubles, menuiseries, revêtements de murs, portes, fenêtres, escaliers, etc., en bois ou en matériaux dérivés du bois.
La présente Norme européenne ne spécifie pas la résistance à la température des joints de colle.

Razvrstitev plastomernih lepil za les za nekonstrukcijsko uporabo

Ta evropski standard določa razvrstitev plastomernih lepil za les na osnovi smole za nekonstrukcijsko uporabo v razrede trajnosti od D1 do D4 na podlagi mokre in suhe trdnosti veznih linij, izmerjene pod določenimi pogoji po različnih načinih priprave.
Za posebne načine uporabe se lahko uporabljajo dodatni preskusi, ki ne spadajo na področje uporabe tega standarda.
Lepila, opredeljena v tem standardu, so primerna za vezavo pohištva in notranjih konstrukcij, opažev, vrat, oken, stopnic itd., izdelanih iz lesa ali lesnih proizvodov.
Ta evropski standard ne določa temperaturne odpornosti veznih linij.

Overview

EN 204:2016 is the CEN European Standard that classifies thermoplastic resin based wood adhesives for non-structural applications. The standard assigns adhesives to durability classes D1 to D4 based on measured dry and wet bond strength of thin bond-lines after specified conditioning sequences. EN 204:2016 supports consistent product selection, quality control and regulatory compliance for interior and some exterior timber applications.

Key Topics

  • Durability classes (D1–D4): Defined by typical climatic conditions and fields of application (for example interiors with limited moisture exposure through to exterior applications with protective coating).
  • Test basis: Classification is based on tensile shear strength tests carried out to EN 205:2016 for thin bond-lines and evaluated as mean values from 20 test pieces.
  • Conditioning sequences: The standard prescribes conditioning steps (standard atmosphere, water immersion, boiling water in some sequences) and specifies whether specimens are tested wet or after reconditioning.
  • Standard atmospheres: Control climates are (20 ± 2) °C / (65 ± 5) % RH (20/65) or (23 ± 2) °C / (50 ± 5) % RH (23/50).
  • Scope limits: EN 204:2016 applies to thermoplastic wood adhesives for non-structural uses and does not specify temperature resistance of bond-lines. Special applications may require additional testing outside this standard.

Applications

EN 204:2016 is intended to help manufacturers, specifiers and end-users choose adhesives appropriate to service conditions. Typical applications include:

  • Furniture manufacture and assembly
  • Interior joinery, panelling and stair components
  • Doors, window frames and internal fittings

Practical benefits:

  • Enables consistent comparison of thermoplastic adhesives based on durability class
  • Reduces risk by matching adhesive performance to expected moisture exposure
  • Facilitates manufacturer declarations and product liability clarity

Related Standards

  • EN 205:2016 - Test method for determination of tensile shear strength of lap joints; normative for EN 204 testing.
  • EN 923 - Terms and definitions for adhesives relevant to EN 204.
  • EN 12765 - Classification of thermosetting wood adhesives for non-structural applications (related classification approach).

Notes on Use

  • Classification requires meeting the minimum mean strength values given in EN 204:2016 Table 2 for the conditioning sequences relevant to the assigned durability class.
  • Results from tests where failure occurs in the wood below specified minima are invalid and must be reported with explanation.
  • For special or extreme service conditions (e.g., temperature resistance or unusual exposure), additional tests beyond EN 204:2016 may be necessary.

This summary highlights how EN 204:2016 applies to selection, testing and documentation of thermoplastic wood adhesives for non-structural timber applications.
