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
Note 1 to entry: Part of the Earth is considered as conductive, the electric potential of which is
conventionally taken as zero.
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 a grounded metal base
plate (resilient and MMF floor coverings) or over a PE-foam/PE-foil situated over a grounded 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 approximately (100 × 200) cm 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 × 120) cm and (3 ± 0,5) mm thick, with a vertical
resistance ≥ 10 Ω (measured at 500 V DC according to EN 61340-4-1) shall be used. This PE foam sheet
is laid on a grounded 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 × 120) cm and (0,2 ± 0,1) mm thick is laid on a
earthed metal base plate, as specified in 5.2.

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
NOTE For guidance on the possible effect of the operator’s clothing and other factors on test results, see
informative Annex B.
