Wood and parquet flooring - Determination of bending strength under static load - Test methods

This European Standard specifies methods of determining the bending strength of wood and parquet flooring under static loads: a method with a static line load and a method with a static point load.
The methods apply to wood and parquet flooring installed on a non-continuous support and thus assuming static load-bearing conditions.

Parkett und Holzfußböden - Bestimmung der Biegefestigkeit unter statischer Beanspruchung - Prüfmethoden

Diese Europäische Norm legt Verfahren fest, mit denen die Biegefestigkeit von Holzfußböden unter statischen Belastungen bestimmt wird: ein Verfahren mit einer statischen linearen Kraft und ein Verfahren mit einer statischen Einzelkraft.
Die Verfahren werden bei Holzfußböden angewendet, die auf einer nicht durchgehenden Unterlage an-gebracht sind und folglich tragende Funktion haben.

Parquets et planchers en bois - Détermination de la flexion sous charges statiques - Méthodes d'essais

La présente norme européenne définit des méthodes de détermination des propriétés de flexion des parquets et planchers en bois : une méthode avec une charge linéaire statique et une méthode avec une charge ponctuelle statique.
Les méthodes s’appliquent aux planchers en bois mis en oeuvre sur un support discontinu et par conséquent travaillant sous charge statique.

Lesene in parketne talne obloge - Ugotavljanje upogibnih lastnosti pri statičnih obremenitvah - Preskusne metode

Ta mednarodni standard določa metodi ugotavljanja upogibnih lastnosti lesenih talnih oblog pri statičnih obremenitvah: metodo s statično linijsko obremenitvijo in metodo s statično točkovno obremenitvijo. Metodi veljata za lesene talne obloge, nameščene na prekinjeno podporo, s čimer se predvidijo pogoji statične nosilnosti.

Overview

EN 1533:2010 (CEN) defines standardized test methods for determining bending strength of wood and parquet flooring under static loads. It covers two laboratory procedures - a static line load and a static point load - applied to floor assemblies installed on a non‑continuous support (battens or joists) and assuming static load‑bearing conditions. The standard is intended for reproducible measurement of maximum load leading to failure and for reporting bending strength results.

Key topics and technical requirements

• Test scope: Applies to wood and parquet flooring assembled into test assemblies (typically four elements) fixed to battens or joists.
• Loading methods:
  • Static line load: steel loading head with a rounded contact radius of (15 ± 0.05) mm; axis parallel to support.
  • Static point load: steel loading head with (50 × 50) mm square contact face, edges rounded/bevelled; axis perpendicular to specimen.
• Measurement accuracy:
  • Dimensional instruments: ±1 mm for lengths/spans; ±0.5 mm for widths/thicknesses.
  • Load measurement: accuracy of ±1 %.
• Support and assembly:
  • Rigid support table with adjustable span; support deflection under test < 0.1 mm.
  • Battens: timber density ≥ 400 kg/m³, width (45 ± 1) mm, depth ≥ 45 mm.
  • Assemblies may have ends supported or unsupported by battens, per clause details.
• Conditioning: Two climate options - Climate A (65 ± 5 % RH, 20 ± 2 °C) or Climate B (50 ± 5 % RH, 23 ± 2 °C).
• Test procedure:
  • Alignment tolerances: loading head positioned within ±1 mm of mid‑span/mid‑width as required.
  • Loading rate chosen so failure occurs in (300 ± 120) s.
  • Record Fmax (maximum load) to 1 % accuracy and describe failure mode.
• Results & statistics:
  • Compute mean, standard deviation and characteristic values (5th or 95th percentile) using Student t coefficients.
  • Express results to three significant figures.
• Test report: Specifies required report items (laboratory, sample ID, conditioning, assembly description, dates, results, failure mode, etc.).

Applications and users

• Flooring manufacturers validating product bending strength and durability.
• Independent testing laboratories performing conformity or performance tests.
• Product engineers and R&D teams developing parquet and engineered wood flooring.
• Specifiers, architects and structural engineers requiring verified strength data for design decisions.
• Quality assurance and compliance professionals preparing technical documentation for markets that adopt CEN standards.
