Full title and description

ISO 19210:2017 — Adhesives — Wood adhesives for non-structural applications — Determination of tensile shear strength of lap joints. Method for preparing, conditioning and testing single‑lap bonded wood assemblies to assess tensile shear strength and resistance of thin bond‑line adhesives to hot and cold water exposure. The standard is intended for comparative testing of wood adhesives used in non‑structural applications and does not replace tests on finished products.

Abstract

ISO 19210:2017 specifies a standardized tensile shear (single‑lap joint) test for adhesives used with wood and derived timber products to assess bond strength and resistance to hot and cold water. The method is suitable for comparative assessment of thin bond lines. It excludes adhesives for structural use and tests related to the manufacture of particleboards, fibreboards and plywood. The document defines specimen preparation, conditioning, test procedure, expression of results and reporting requirements.

Scope

Defines a laboratory test method to determine tensile shear strength of lap joints made with adhesives for wood and derived timber products in non‑structural applications. The scope covers preparation of bonded assemblies, specimen dimensions and cutting, conditioning sequences (including hot and cold water treatments), the tensile shear test itself, calculation and expression of results, and test reporting. The standard is intended for comparative assessment of thin bond lines and for evaluating adhesive resistance to water exposure. It does not apply to adhesives intended for structural use nor to routine tests during manufacture of particleboard, fibreboard or plywood, and it does not replace product‑level tests on finished items.

Key topics and requirements

• Test principle — tensile shear (single‑lap) loading of bonded wood adherends with force applied parallel to the grain until failure.
• Specimen preparation — detailed instructions for bonded assemblies and cutting of test pieces (typical test piece dimensions given in the standard for thin bond‑line specimens).
• Representative specimen dimensions — example nominal values used for thin bond‑line tests (panel thickness ≈ 5.0 mm; width ≈ 20.0 mm; total length ≈ 150 mm; overlap ≈ 10.0 mm; nominal bond‑line ≈ 0.1 mm).
• Conditioning — standard laboratory atmospheres and specified hot/cold water treatments and conditioning sequences to evaluate durability and water resistance.
• Number of tests and statistics — prescribed number of test pieces per conditioning sequence to allow meaningful comparison (standard indicates multiple pieces per sequence; typical practice is 20 specimens per sequence for comparative assessment).
• Expression of results — calculation of tensile shear strength, reporting of failure modes (adhesive, cohesive, substrate failure), and presentation of test data.
• Test report content — identification of adhesive and substrate, specimen dimensions, conditioning details, test machine and speed, individual and mean results, and observed failure types.

Typical use and users

Used by adhesive manufacturers for product development and comparative performance data; independent testing and accreditation laboratories for type‑testing and verification; furniture, joinery and panel product manufacturers for selecting appropriate non‑structural adhesives; certification bodies and regulatory organizations when assessing adhesives for specified non‑structural applications; and researchers studying bond performance and durability of wood adhesives.

Related standards

Key related documents include the European standard EN 205 (Adhesives — Wood adhesives for non‑structural applications — Determination of tensile shear strength of lap joints), and ISO 19209:2017 (Classification of thermoplastic wood adhesives for non‑structural applications), which together address classification and test methods for thermoplastic wood adhesives. Other adjacent test standards and national/adopted versions (EN/CEN adoptions) cover complementary durability and load tests for wood adhesives.

FAQ

Q: What is this standard?

A: ISO 19210:2017 is an international test method that specifies how to determine the tensile shear strength of single‑lap wood adhesive joints for non‑structural applications, with procedures for specimen preparation, conditioning and testing.

Q: What does it cover?

A: It covers laboratory procedures to prepare bonded assemblies, condition specimens (including hot and cold water treatments), perform tensile shear tests on single‑lap joints and report strength results and failure modes. It is intended for comparative assessment of adhesives with thin bond lines and for evaluating resistance to water exposure.

Q: Who typically uses it?

A: Adhesive producers, test laboratories, product manufacturers (furniture, doors, interior woodwork), certification bodies, standards committees and researchers involved with wood adhesive performance and durability.

Q: Is it current or superseded?

A: The standard was published 27 July 2017 (Edition 1) and was subject to ISO systematic review and confirmed in 2022; it remains the current ISO document for this test method.

Q: Is it part of a series?

A: Yes. ISO 19210:2017 sits with related ISO documents addressing non‑structural wood adhesives — notably ISO 19209:2017 (classification of thermoplastic wood adhesives) and corresponding European standards such as EN 205:2016; these documents together cover classification and test methods for non‑structural wood adhesives.
