Overview
EN 383:2007 - Timber Structures: Test methods for determination of embedment strength and foundation values for dowel type fasteners is a CEN laboratory standard that specifies how to measure the local compressive capacity of timber, glued laminated timber and wood‑based sheet products when loaded by dowel‑type fasteners (bolts, nails, dowels). The standard defines specimen geometry, environmental conditioning, apparatus calibration, loading procedures and the basic calculation of embedment strength (fh) and related foundation moduli from load–deformation data.
Key topics and requirements
- Scope & materials: Applies to solid timber, glued laminated timber and wood‑based panels with dowel type fasteners (plain or patterned surfaces).
- Test pieces: Rectangular prism specimens with fastener axis perpendicular to the surface. Specimen dimensions depend on fastener section dimension d (guidance: thickness t ≈ 1.5d to 4d; panel thickness = produced thickness).
- Conditioning: Specimens must be conditioned to constant mass at (65 ± 5) % RH and (20 ± 2) °C; constant mass = two weightings 6 h apart within 0.1 %.
- Apparatus & calibration: Calibration using a steel specimen with a tight-fitting pin of the same diameter as the fastener to remove apparatus deformation from results. Load and displacement measurement accuracies are specified (load ±1 %, displacement ±1 % or 0.02 mm for small displacements).
- Loading procedure: Includes a preload cycle to 0.4·Fmax,est (hold 30 s), reduction to 0.1·Fmax,est (30 s), then monotonically increase to Fmax within (300 ± 120) s. Tests stop at maximum load or deformation limit.
- Measurements & calculations: Embedment strength is calculated from measured maximum load: fh = Fmax / (d · t). The standard also defines initial, modified and elastic foundation moduli (derived from corrected load–deformation curves) and prescribes corrections for apparatus stiffness.
- Reporting: Test reports must record sampling, species, density, moisture content, fastener type and surface treatment, specimen geometry, conditioning, results, means, standard deviations and failure modes.
Applications and who uses it
- Structural timber test laboratories performing product qualification and research.
- Fastener manufacturers validating dowels, nails and bolts for timber connections.
- Structural engineers and designers needing validated embedment data for connection design and numerical models.
- Certification bodies and standards committees referencing laboratory values for national codes and design guidelines.
Related standards (if applicable)
- EN standards and national timber design standards that use embedment strength and foundation modulus data for connection design (refer to applicable national annexes and timber design codes).
Keywords: EN 383:2007, embedment strength, foundation values, dowel type fasteners, timber structures, test methods, load–deformation, foundation modulus, specimen conditioning.
