(Main)Adhesives - Classification of thermoplastic wood adhesives for non-structural applications
Adhesives - Classification of thermoplastic wood adhesives for non-structural applications
ISO 19209:2017 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 ISO 19209:2017 can be applicable. The adhesives specified in ISO 19209:2017 are suitable for the bonding of furniture and interior structures, panelling, doors, windows, stairs, etc. made of wood or derived timber products. ISO 19209:2017 does not specify the temperature resistance of bond lines.

Overview
ISO 19209:2017 - "Adhesives - Classification of thermoplastic wood adhesives for non-structural applications" defines a durability classification system (D1 to D4) for thermoplastic resin–based wood adhesives used in non‑structural woodworking. The standard classifies adhesives according to measured dry and wet bond‑line strength after specified conditioning sequences and references ISO 19210 for the tensile shear strength test of lap joints. ISO 19209:2017 applies to bonding of furniture and interior structures, panelling, doors, windows, stairs and other timber products, and explicitly does not specify bond‑line temperature resistance.
Key topics and technical requirements
- Durability classes D1–D4: Class assignments are based on performance after defined conditioning (dry, wet and boiling exposures) that simulate climatic and service conditions.
- Test method: Bond‑line strength is measured following ISO 19210 (tensile shear strength of lap joints). Results use the mean of 20 test pieces per conditioning sequence; detailed reporting of valid and invalid results is required.
- Conditioning sequences: Tests include exposure to a standard atmosphere ((20 ± 2) °C/65 % RH or (23 ± 2) °C/50 % RH), short and long water immersion, and boiling water in prescribed sequences. Specific minimum strength values per durability class are given in Table 2 of the standard.
- Acceptance rules: Results where failure occurs in the wood below specified minima are invalid. Specimens with form irregularities are accepted only if they meet requirements; otherwise they are reported as invalid.
- Scope limits: The standard covers thermoplastic wood adhesives for non‑structural applications; special or more demanding applications may require additional testing beyond ISO 19209:2017.
Applications and users
ISO 19209:2017 is intended for:
- Adhesive manufacturers and R&D labs - to classify thermoplastic wood adhesives and publish durability claims.
- Quality and test laboratories - to perform standardized tensile shear and conditioning tests referenced by the standard.
- Furniture, joinery and timber product manufacturers - to select adhesives appropriate for interior, humid or exposed but protected installations.
- Specifiers, procurement and regulators - to compare adhesive durability classes (D1–D4) when writing specifications or verifying compliance.
Typical use cases: furniture assembly, interior panelling, doors and window joinery, stair construction, and other non‑structural timber bonding where moisture exposure is a concern.

ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
