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.

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.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
ISO and IEC maintain terminological databases for use in standardization at the following addresses:
• IEC Electropedia: available at https://www.electropedia.org/
• ISO Online browsing platform: available at https://www.iso.org/obp
3.1
floor covering panel with mechanical locking system
rigid or semi-rigid floor covering, typically in a plank or tile format, consisting of a compact layer of a
substrate and a decorative surface layer for floating installation
3.2
decorative layer
layer providing visual and aesthetic properties, intended to be the visible side when the floor is
installed
Note 1 to entry: Decorative layers can consist of resilient layers including cork, layers with aminoplastic
thermosetting resins and wood veneer layers with a thickness < 2,5 mm and textile surfaces.
3.3
squareness
measurement of the amount each corner of the tile deviates from 90°
3.4
straightness
property of an edge to be straight, unbent
4 Principles
4.1 Thickness
The test piece is placed between two parallel plates, and the distance between them is measured.
4.2 Length and width
The surface dimensions of a modular mechanical locked floor covering panel are measured by a contact
method at defined positions in each direction. The measurement is taken at the edges of the surface
layer.
4.3 Squareness
To assess the squareness, each corner of a right-angled panel is fitted into the dihedral angle of a
precision square and the maximum gap between the arm of the square and the ends of the panel is
measured.
4.4 Straightness
To assess the straightness, the maximum opening between the panel and the straight edge is measured
on the concave side using a suitable gauge.
4.5 Flatness
To assess width flatness the deviation in height is measured by direct contact with a dial gauge
maintained at constant height. To
