Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

INTERNATIONAL STANDARD ISO 24334:2014(E)
Laminate floor coverings — Determination of locking
strength for mechanically assembled panels
1 Scope
This International Standard specifies a method for the determination of the locking strength of
joints between laminate floor covering panels which are assembled with both vertical and horizontal
mechanical locking systems.
2 Normative references
The following documents, in whole or in part, are normatively referenced in this document and are
indispensable for its application. For dated references, only the edition cited applies. For undated
references, the latest edition of the referenced document (including any amendments) applies.
ISO 7500-1, Metallic materials — Verification of static uniaxial testing machines — Part 1: Tension/compression
testing machines — Verification and calibration of the force-measuring system
3 Principle
Mechanically assembled panels with mechanical locking systems are pulled apart to an opening of
0,20 mm or until the lock breaks.
4 Apparatus
The following set of equipment is needed:
4.1 Tensile testing machine, verified and calibrated in accordance with ISO 7500-1 and conforming to
class 3 for the force range which is applied for the locking strength measurement.
4.2 External extensometer or optical measurement system, with an accuracy of 0,01 mm.
4.3 Two clamping devices, attached to the tensile testing machine to hold the grippers.
1)
NOTE Zwick/Roell clamps Type 8355 , 20 kN are found suitable for the purpose.
4.4 Two grippers, 50 mm × 210 mm, attached to the clamping devices to hold the specimen with an
anti-slip coating material (see Figure 6 and Figure 7).
4.5 Sliding calliper, with an accuracy of 0,1 mm, to determine the length, width, and thickness of
the specimen.
4.6 Saw, for cutting the specimen.
4.7 Balance, with an accuracy of 0,1 g.
1) Zwick/Roell clamps Type 8355 are examples of suitable products available commercially. This information
is given for the convenience of users of this document and does not constitute an endorsement by ISO of these
products. Equivalent products may be used if they can be shown to lead to the same results.

4.8 Calibration plate, iron steel 200 mm × 200 mm, (7 ± 1) mm thick, to adjust the clamping device
coplanar in the tensile testing machine.
5 Sampling and conditioning of panels
Sample five panels, preferably from the same package, for the preparation of five test specimens for the
short side locks and five for the long side locks. If panel dimensions allow it, the sampling of the short
side and the long side can come from the same panel.
