European foreword
This document (EN 1815:2025) has been prepared by Technical Committee CEN/TC 134 “Resilient,
textile, laminate and modular mechanical locked floor coverings”, the secretariat of which is held by NBN.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by April 2026, and conflicting national standards shall be
withdrawn at the latest by April 2026.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document supersedes EN 1815:2016.
— modular mechanical locked floor coverings were added to the Title and Scope;
— correction of the normative references in Clause 2 related to the new technical parameter;
— the test principle description in Clause 4 was divided in method A and B;
— a description of a conditioned room was added as 5.1;
— technical parameters of the new EPDM sole in 5.5;
— Clause 6, “Preparation of test pieces for method A” was integrated;
— 8.2.2 “Discharging” was modified;
— the Annex A with the description of the test sandals was added and Figure A.1 was replaced.
Any feedback and questions on this document should be directed to the users’ national standards body.
A complete listing of these bodies can be found on the CEN website.
According to the CEN-CENELEC Internal Regulations, the national standards organisations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia,
Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland,
Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Republic of North
Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Türkiye and the United
Kingdom.
1 Scope
This document specifies a method for determining the body voltage (BV) generated when a person
wearing standardized footwear walks on a resilient, modular mechanical locked floor coverings (MMF)
or laminate floor covering. The test method can be used under laboratory conditions as well as in situ.

3.1
static electrical propensity
tendency for charge to be generated by a person walking on the floor covering
3.2
earthed
connected to a reference earth
4 Principle
4.1 Method A
A floor covering is evaluated for static electrical propensity by means of a walking test with an operator
using a pair of standard sandals, walking over the floor covering situated over an earthed metal base plate
(resilient and MMF floor coverings) or over a PE-foam/PE-foil situated over an earthed metal base plate
(laminate floor coverings).
4.2 Method B
A floor covering is evaluated for static electrical propensity by means of a walking test with an operator
using a pair of standard sandals, walking over the floor covering in in situ conditions.
5 Apparatus
5.1 Conditioned room (Method A)
Environmental conditions for conditioning before testing and the test provided in a room or a chamber
with following specifications:
a temperature of (23 ± 2) °C and relative humidity of (25 ± 5) %.
5.2 Substructure for resilient and MMF floor coverings (Method A)
An earthed metal base plate shall be used, e.g. a stainless-steel plate of at least (1,8 × 0,9) m and
approximately 1 mm thick.
5.3 Substructure for laminate floor coverings (Method A)
5.3.1 Laminate floor coverings without attached sound absorbing material
A PE foam sheet of approximately 220 cm × 120 cm and (3 ± 0,5) mm thick, with a vertical
resistance ≥ 10 Ω (measured at 500 V DC according to EN IEC 61340-4-1) shall be used. This PE foam
sheet is laid on an earthed metal base plate, as specified in 5.2.
NOTE In case of underlay material is not available in one piece, it is appropriate to use tape to create a sufficient
area from the origin foam roll material.
5.3.2 Laminate floor coverings with attached sound absorbing material
A water vapour barrier PE foil of approximately 220 cm × 120 cm and (0,2 ± 0,1) mm thick is laid on a
earthed metal base plate, as specified in 5.2.
5.4 Test sandals
The test sandals (see Annex A) shall be reserved exclusively for use in this test method. The test sandals
shall be open sandals of European size 42 (Mondopoint size 270/100) and with straps mounted to fit
various foot sizes. An EPDM sole material (5.5) shall be used. The resistance between the metal plate and
8 9
the operator standing on it wearing the sandals with the soles shall be (10 to 10 ) Ω to be measured at
a voltage of 100 V.
The PE-foam (EN 1
