European Standard the status of a national standard without any alteration. Up-to-date lists and bibliographical references
concerning such national standards may be obtained on application to the CEN-CENELEC Management Centre or to any CEN
member.
This European Standard exists in three official versions (English, French, German). A version in any other language made by
translation under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC Management
Centre has the same status as the official versions.

3.1
vertical resistance R1
electrical resistance measured between a tripod electrode on the surface of a test piece and an electrode
attached to the underside of the test piece
Note 1 to entry: See Figure 1 for tripod electrode and see Figure 2 for testing of vertical resistance.
3.2
resistance to earth R2
electrical resistance measured between a loaded tripod electrode on the surface of a laid floor covering
and earth
3.3
surface resistance R3
electrical resistance measured between two tripod electrodes set up at a fixed distance of 100 mm apart
on a laid floor covering
Note 1 to entry: See Figure 4 for the electrical resistance measured between two tripod electrodes and see
Figure 3 for distance of 100 mm apart on a laid floor covering.
4 Sampling
For method A or when measurements are done in laboratory, take a representative sample from the
whole of the available material. In the case of rolls, take approximately a third of the test pieces from
the area close to the edges, the distance between the outer edge of the sample and the nearest edge of
the roll being between 50 mm and 100 mm.
5 Apparatus and reagents
5.1 Tripod electrode
The tripod electrode (Figure 1) shall be capable of comprising a triangular aluminium plate with an
insulating layer on the upper surface and three cylindrical feet of conductive rubber on the underside at
a distance of 180 mm apart.
The rubber feet shall have a hardness in accordance with ISO 48 of 50 IRHD to 70 IRHD, and the
electrical resistance of each rubber foot shall be less than 10 Ohm when t
