Modular mechanical locked floor coverings (MMF) - Determination of geometrical characteristics

This document specifies test methods for the determination of geometrical characteristics of modular mechanical locked floor covering panels in respect of thickness, length, width, squareness, straightness, width flatness, length flatness, openings between assembled elements and height differences between assembled elements.
The geometrical characteristics of modular mechanical locked panels are important considerations because installed flooring will have an objectionable appearance if these performance criteria are not followed. This can cause the installed panels to line up unevenly, producing unsightly seams, uneven surfaces and corners that do not match.

Modulare mechanisch verriegelnde Fußbodenbeläge (MMF) - Bestimmung der geometrischen Eigenschaften

Dieses Dokument legt Prüfverfahren zur Bestimmung geometrischer Eigenschaften von modularen mechanisch verriegelnden Fußbodenpaneelen in Bezug auf die Dicke, Länge, Breite, Rechtwinkligkeit, Geradheit, Ebenheit in der Breite, Ebenheit in der Länge, Fugenöffnungen zwischen montierten Elementen und Höhenunterschiede zwischen montierten Elementen fest.
Die geometrischen Eigenschaften von modularen mechanisch verriegelnden Fußbodenpaneelen sind wichtige Faktoren, da verlegter Bodenbelag ein störendes Erscheinungsbild haben kann, wenn diese Leistungskriterien nicht erfüllt werden. Das kann dazu führen, dass die verlegten Paneele nicht gleichmäßig ausgerichtet sind, was zu unansehnlichen Fugen, unebenen Oberflächen und nicht aufeinander passenden Ecken führt.

Revêtements de sol modulaires à verrouillage mécanique (MMF) - Détermination des caractéristiques géométriques

Le présent document spécifie les méthodes d'essai pour déterminer les caractéristiques géométriques des panneaux de revêtements de sol modulaires à verrouillage mécanique par rapport à l'épaisseur, la longueur, la largeur, l'équerrage, la rectitude, la planéité en largeur, la planéité en longueur et les ouvertures ainsi que les différences de hauteur entre les éléments assemblés.
Les caractéristiques géométriques des panneaux modulaires à verrouillage mécanique sont des facteurs importants à prendre en compte car il en va de la bonne apparence du sol installé si ces critères de performance ne sont pas respectés. Les panneaux installés peuvent, le cas échéant, être alignés de façon désordonnée, ce qui entraîne des raccords disgracieux, des surfaces irrégulières et des angles non concordants.

Overview

EN 17539:2021 is a CEN European standard that defines test methods for determining the geometrical characteristics of modular mechanical locked floor coverings (MMF). It covers dimension and form measurements that influence the visual appearance and jointing behaviour of plank- or tile-format floating floors. Key measured properties include thickness, length, width, squareness, straightness, width flatness, length flatness, gaps between assembled elements and height differences between assembled panels.

Key topics and technical requirements

• Scope: Test methods for MMF panels covering thickness, surface dimensions, edge straightness, corner squareness, flatness and assembly openings/height differences.
• Sampling: Typical sample set = five panels for dimensional tests; add three more (eight total) for openings and height-difference testing. Avoid using the first and last panels from a pack.
• Conditioning: Example conditioning given - 24 h at (23 ± 2) °C and (50 ± 5) % RH for resilient/textile surfaces without moisture-sensitive substrates.
• Principles & procedures:
  • Thickness measurement between parallel plates using a dial gauge (uncertainty 0.01 mm; 0.1 mm over 25 mm for textiles).
  • Length/width by contact measurement (permissible error 0.05 mm up to 610 mm; 0.1 mm over 610 mm).
  • Squareness measured using a precision “L” square (90° ± 0.01° tolerance).
  • Straightness assessed with a calibrated straight edge (max deviation 0.05 mm per 1 000 mm) and thickness gauges.
  • Width flatness measured with a dial gauge arrangement featuring three supports and a rounded tip (gauge accuracy ±0.01 mm).
  • Openings and height differences measured on assembled specimens using thickness gauges (0.05–0.50 mm steps), callipers or depth gauges (scale interval 0.05 mm).
• Apparatus tolerances: Several instrument accuracy and straightness limits are specified to ensure repeatability and precision.

Applications and who uses this standard

EN 17539:2021 is used to:

• Support product specification standards and component conformity assessments (CEN/TC 134 common test methods).
• Guide manufacturers in quality control and dimensional tolerancing for MMF products.
• Provide test laboratories with harmonized procedures for inter-lab comparability.
• Help architects, specifiers and procurement teams evaluate aesthetic and installation risks related to panel geometry.
• Inform installers about expected joint/gap and alignment behaviour to avoid objectionable appearance after installation.

Related standards

• Developed by CEN/TC 134, EN 17539 is intended as a generic set of test methods to be referenced in the common part of product-specific floor covering standards. National adopters must implement this European Standard as a national standard.

Introduction
The technical committee CEN/TC 134 decided to develop a series of generic test methods able to
demonstrate the characteristics of modular mechanical locked floor covering panels. This series of test
methods will be used in the common part of individual product specification standards.
1 Scope
This document specifies test methods for the determination of geometrical characteristics of modular
mechanical locked floor covering panels in respect of thickness, length, width, squareness, straightness,
width flatness, length flatness, openings between assembled elements and height differences between
assembled elements.
The geometrical characteristics of modular mechanical locked panels are important considerations
because installed flooring will have an objectionable appearance if these performance criteria are not
followed. This can cause the installed panels to line up unevenly, producing unsightly seams, uneven
surfaces and corners that do not match.
