Diese Europäische Norm legt eine Scherprüfung zur Charakterisierung von Klebstoffen in einer Klebung fest. Das Schubspannungs-Gleitungs-Verhalten eines Klebstoffes (einschließlich des Schubmoduls) ist für die Auslegung, z. B. bei Finite-Elemente-Methoden, von Nutzen.

Overview
EN 14869-1:2011 - "Structural adhesives - Determination of shear behaviour of structural bonds - Part 1: Torsion test method using butt‑bonded hollow cylinders" (modified from ISO 11003‑1:2001) specifies a standardized torsion test to characterize the shear stress/strain behaviour of structural adhesives in bonded joints. The method yields the adhesive shear modulus and shear strength data used for advanced design and analysis, including input for finite element analysis (FEA).
Key topics and technical requirements
- Principle: Measure torque and relative displacement while twisting two butt‑bonded hollow cylinders until the joint reaches a target deformation or fails. Derive shear stress and shear strain for the adhesive layer and calculate shear modulus from the linear portion of the stress–strain curve.
- Specimen geometry: Recommended specimen sizes A, B, C with outer/inner radii (ro/ri): A (36/24 mm), B (30/20 mm), C (12/10 mm). Bond width should be ≥10 × bond thickness; preferred bond thickness 0.20 mm (range 0.05–0.5 mm for special adhesives).
- Adherend material: Aluminium alloy or steel recommended; adherend shear modulus must be ≥10× adhesive shear modulus.
- Bonding and alignment: Coaxial alignment with maximum lateral displacement ≤ 0.002·ro and bond thickness variation ≤ 5%. Use surface preparation per EN 13887 or methods to ensure cohesive adhesive failure.
- Test apparatus: Torsion machine capacity ≥ 300 N·m (preferably 1 000 N·m). Displacement sensor range 2 µm–1 000 µm, accuracy ±1 µm. Temperature chamber required for non‑ambient tests.
- Test conditions: Test temperature as per EN ISO 291 (specimen temperature measured within ±1 °C). Shear rate range 0.0005 s‑1 to 0.02 s‑1 (preferred 0.01 s‑1).
- Repetition and reporting: Minimum five specimens. Test report must reference EN 14869‑1 and include adhesive ID, adherend material, surface prep, bonding details, bond thickness, temperature, individual and averaged results (shear modulus, peak shear stress/strain), failure observations (per EN ISO 10365), and any deviations.
Applications and users
- Provides quantitative shear properties for adhesives used in structural bonding.
- Primary users:
- Adhesive manufacturers (product characterization, quality control)
- Test laboratories (type testing, certification)
- Design and simulation engineers (FEA material input)
- Aerospace, automotive, marine and construction engineers evaluating bonded joints
- Useful for R&D, material selection, failure analysis and validating adhesive models in structural simulations.
