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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
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.
ISO 22653 was prepared by CEN (as EN 12826:2000) and was adopted, under a special “fast-track
procedure”, by Technical Committee ISO/TC 216, Footwear, in parallel with its approval by the ISO member
bodies.
For the purposes of international standardization, a list of corresponding International and European
Standards for which equivalents are not given in EN 12826 has been added as Annex ZZ.

for footwear.
3 Definitions
For the purposes of this standard the following definitions apply:

perpendicular force acting upon the two surfaces
3.3
kinetic angle of surface drag (D )
k

initiated by a standard impulse
3.4
static angle of surface drag (D )
s

mass and momentum
4 Apparatus and material
The following apparatus and material shall be used:
4.1 Method A
4.1.1 A sled, (150 mm ± 1 mm) long x (100 mm ± 1 mm) wide having a mass of 700 g ± 15 g to which
a lining or insock test specimen is attached (see 5.1.1) and a test specimen support of cellular rubber, or
plastics material, 3 mm thick and of medium apparent density. The surface of the sled is flat and smooth
or polished. The edges of the sled do not contain any burrs or roughness.

included in the circuit in series with the electric motor (4.2.1.4) and is positioned at
4.2.1.5 Microswitch
the top end of the platform (4.2.1.1) so that the actuating lever of the switch may be depressed by the
back edge of the specimen carrier (4.2.1.3) resting on the melton cloth. A suitable stop shall be provided
such that the distance of travel of the specimen carrier between the stop and the contact breaking
position of the switch is 4,5 mm ± 0,5 mm.
The force required to depress the actuating lever of the microswitch shall be between 40 mN and 80 mN.
A suitable apparatus is shown schematically in figure 2.
