4.9 Silicon carbide paper, 400 grit size, mounted on a rigid block with a flat face measuring
100 mm × 70 mm and mass (1 200 ± 120) g.
NOTE This can be achieved using steel to make a block 22 mm thick.
4.10 Rigid wedges having a (7,0 ± 0,5)° angle for setting the contact angle. The tip of each wedge
(Figure 1) shall be truncated to a maximum height of 0,5 mm as judged by graduated eyepiece or
equivalent means. The width of the wedge should be sufficient to ensure that the full width of the heel
or forepart shall be fully supported by the wedge. For the heel test, the length shall be sufficient to
support the full length of the heel but shall not make contact with the forepart [see Figure 2 a)]. For
the forepart test, the length of the wedge shall be sufficient to support the heel and forepart of the shoe
[see Figure 2 b)].
The purpose of the wedge when used in 6.2.2 and C.4.3 is to ensure that the test footwear or specimen
S96 is elevated by no more than ≈1 mm above the test surface when the contact angle is being set. To
facilitate this, the wedge may be marked with a line parallel to, and ≈4 mm from, the truncated edge at
the position where the wedge has a height of ≈1 mm, as shown in Figure 1.

5 Sampling and conditioning
5.1 Sampling
Unless otherwise specified, use a minimum of two samples, one left and one right, of the same type of
footwear of the same size.
5.2 Conditioning
The test items shall be conditioned prior to the test at (23 ± 2) °C and (50 ± 5) % RH for a minimum
of 24 h. If necessary, the sample may be removed from this standard atmosphere provided that its
temperature is maintained at (23 ± 2) °C, that testing starts within 30 min after removal from this
standard atmosphere and that the testing is carried out at (23 ± 2) °C.
6 Test method
6.1 Principle
The item of footwear to be tested is put on a surface, subjected to a given normal force, and moved
horizontally relative to the surface (or the surface is moved horizontally relative to the item of
footwear). Both the frictional force and normal force are measured and the dynamic CoF is calculated.
For each of the required measurements performed in accordance with this document, a corresponding
estimate of the uncertainty of measurement should be evaluated. One of the following approaches shall
be used:
[2]
— a statistical method, e.g. that given in ISO 5725-2 ;
[3]
— a mathematical method, e.g. that given in ISO/IEC Guide 98-3 ;

— JCGM 100:2008 .
6.2 Test modes and test conditions
6.2.1 The footwear shall be tested in one or more of the following modes (see Figure 2):
a) forward heel slip at angled contact;
b) backward slip on the forepart;
c) forward flat slip.
NOTE The heel test mode is considered the most important test mode in relation to reducing the risk of
pedestrian slip.

In the heel test mode the footwear moves forward in the heel to toe direction. The contact angle
between the bottom of the main area of the heel, not including any profile or chamfer at the rear edge of
the heel, and the floor shall be (7,0 ± 0,5)° [see Figure 2 a)], determined using a rigid wedge (4.10) placed
on the floor, the leading edge of the wedge shall be orthogonal to the direction of sliding movement.
The shoemaking last, with the footwear mounted on it, shall be lowered onto the wedge under its own
weight and adjusted until the footwear heel sits flat on the angled face of the wedge with ≈4 mm of
the wedge extending beyond the rearmost contact point of the heel with the face of the wedge. The
footwear forepart shall not contact the surface or the rigid wedge.
In the forepart test mode the footwear moves backwards in the toe to heel direction. The contact angle
between the bottom of the shoe and the floor shall be (7,0 ± 0,5)° [see Figure 2 b)] determined using a
rigid wedge (4.10) placed on the floor. The shoemaking last (4.1.1 or 4.1.2), with the footwear mounted
on it, shall be lowered onto the wedge under its own weight and adjusted until the footwear bottom sits
flat on the angled face of the wedge with ≈4 mm of the wedge extending beyond the foremost contact
point of the forepart with the face of the wedge.
For the flat test mode, the footwear shall be fitted onto the mechanical foot (4.1.3) or the manufacturer's
shoemaking last (4.1.2). The mechanical foot shall be orientated such that the longitudinal axis of the
mechanical foot is aligned parallel to the direction of sliding movement. The footwear shall be fitted onto
the mechanical foot with the heel contact plate placed centrally in the heel seat with a small gap between
the back edge and sides of the insole and with the forepart contact plate positioned approximately central
to the forepart (see Figure 4). If using a manufacturer's shoemaking last in place of the mechanical foot,
then the last shall be aligned such that the footwear attains the same orientation of the outsole tread
pattern relative to the direction of slip as would be achieved if using a mechanical foot.

4.4 Steel floor, consisting of a stainless steel plate.
NOTE 1 For example, steel Number 1.4301, Type 2G (cold rolled, ground) conforming to EN 10088-2:2005.
Surface roughness shall be measured in the area where the slip measurements are actually made.
Measurements shall be made at 10 locations within this area and in the direction parallel to the sliding
movement. At each location, measurements shall be made with a sampling length of 0,8 mm, taking five
sampling lengths per location (evaluation length 4,0 mm).
The average roughness, R , shall be measured in accordance with ISO 4287. The overall mean value
z
from all 10 locations shall be for R between 1,6 μm and 2,5 µm.
z
When the roughness parameter does not conform to the above specifications, the steel shall be
prepared using silicon carbide abrasive paper or cloth for polishing in a backwards and forwards,
linear motion, using a succession of reducing grit sizes. The polishing direction of each operation shall
be perpendicular to the preceding operation with the final direction being parallel to the test direction.
The preparation shall continue until the roughness parameter falls within the above specifications.
New steel floor plates shall also be prepared by this method.
NOTE 2 Grit sizes 100 to 600 can be suitable.
4.5 Pressed ceramic tile floor, as specified in Annex B. The tiles shall not be modified in any way, for
example, by mechanical or chemical treatment other than as allowed in Annex B.2.

4.6 Other floors-lubricant conditions, for example, wood, concrete, stone and polymeric flooring,
and lubricants may be used. The floor/lubricant combination used shall be characterized by determining
the coefficient of friction in accordance with Annex C.
4.7 Mechanism for inducing movement between the footwear and the surface at a time and speed as
specified in Clause 6.
4.8 Device for measuring the frictional force between the footwear and surface during the
measurement period to an accuracy of 2 % or better.
4.9 Silicon carbide paper, 400 grit size, mounted on a rigid block with a flat face measuring
100 mm × 70 mm and mass (1 200 ± 120) g.
NOTE This can be achieved using steel to make a block 22 mm thick.
4.10 Rigid wedges having a (7,0 ± 0,5)° angle for setting the contact angle. The tip of the wedge (Figure
1) shall be truncated to a maximum height of 0.5 mm as judged by graduated eyepiece or equivalent
means. The width of the wedge should be sufficient to ensure that the full width of the heel or forepart
shall be fully supported by the wedge. For the heel test, the length shall be sufficient to support the full
length of the heel but shall not make contact with the forepart [see Figure 3a)]. For the forepart test, the
length of the wedge shall be sufficient to support the heel and forepart of the shoe [see Figure 3b)].
The purpose of the wedge when used in 6.2.2 and C.4.3 is to ensure that the test footwear or specimen
S96 is elevated by no more than approximately 1 mm above the test surface when the contact angle is
being set. To further facilitate this, the wedge may be marked with a line parallel to, and approximately
4 mm from, the truncated edge at the position where the wedge has a height of 1 mm, as shown in
Figure 1.

4.11 Glycerol aqueous solution with a viscosity of (0,2 ± 0,1) Pa·s. At 23 °C this corresponds to an
aqueous solution containing a mass fraction of approximately 85,6 % to 92,8 % glycerol. For other
temperatures, see Table 1 (values for temperatures in the range given in Table 1 may be interpolated).
The solution shall be replaced 30 min after exposure to the ambient atmosphere unless it can be shown
to still comply with Table 1.
NOTE As a solution containing a mass fraction of approximately 90 % glycerol is hygroscopic in air with a
relative humidity of more than 32 %, it is advisable to use solutions with a mass fraction of approximately 90,0 %
to 92,5 % glycerol.

5 Sampling and conditioning
5.1 Sampling
Unless otherwise specified, use a minimum of two samples of the same type of footwear of the same size.
5.2 Conditioning
The test items shall be conditioned prior to the test at (23 ± 2) °C and (50 ± 5) % RH for a minimum
of 24 h. If necessary, the sample may be removed from this standard atmosphere provided that its
temperature is maintained at (23 ± 2) °C, that testing starts within 30 min after removal from this
standard atmosphere and that the testing is carried out at (23 ± 2) °C.
6 Test method
6.1 Principle
The item of footwear to be tested is put on a surface, subjected to a given normal force, and moved
horizontally relative to the surface (or the surface is moved horizontally relative to the item of
footwear). Both the frictional force and normal force are measured and the dynamic CoF is calculated.
For each of the required measurements performed in accordance with this standard, a corresponding
estimate of the uncertainty of measurement should be evaluated. One of the following approaches shall
be used:
— a statistical method, e.g. that given in ISO 5725-2 [2];
— a mathematical method, e.g. that given in ISO/IEC Guide 98-3 [3];
— uncertainty and conformity assessment as given in ISO/IEC Guide 98-4 [4];
— JCGM 100:2008[5]

6.2 Test modes and test conditions
6.2.1 The footwear shall be tested in one or more of the following modes (see Figure 3):
a) forward heel slip at angled contact;
b) backward slip on the forepart;
c) forward flat slip.
NOTE The heel test mode is considered the most important test mode in relation to reducing the risk of
pedestrian slip.
6.2.2 For the heel and forepart test modes, the footwear shall be fitted onto a shoemaking last (4.1.1
or 4.1.2). The inside tangent of the shoemaking last, as defined by a straight line placed against the heel
and joint swell on the inside of the shoemaking last (line A-B in Figure 4), shall be aligned parallel to the
direction of sliding movement (see Figure 4).
In the heel test mode the footwear moves forward in the heel to toe direction. The contact angle between
the bottom of the main area of the heel, not including the any profile or chamfer at the rear edge of the
heel, and the floor shall be (7,0 ± 0,5)° (see Figure 3a), determined using a rigid wedge (4.10) placed
on the floor, the leading edge of the wedge shall be orthogonal to the direction of sliding movement.
The shoemaking last, with the footwear mounted on it, shall be lowered onto the wedge under its own
weight and adjusted until the footwear heel sits flat on the angled face of the wedge with approximately
4 mm of the wedge extending beyond the rearmost contact point of the heel with the face of the wedge.
The footwear forepart shall not contact the surface or the rigid wedge.
NOTE For footwear with curved outsoles, set the angle of the shoemaking last such that the vertex is
approximately the foremost point of contact between the outsole and the floor under full vertical load, see
Figure 2. The vertex is the central point of contact between the outsole and floor when the footwear is rested
horizontally on the floor without additional load (i.e. without last).

In the forepart test mode the footwear moves backwards in the toe to heel direction. The contact angle
between the bottom of the shoe and the floor shall be (7,0 ± 0,5)° (see Figure 3b) determined using a
rigid wedge (4.10) placed on the floor. The shoemaking last (4.1.1 or 4.1.2), with the footwear mounted
on it, shall be lowered onto the wedge under its own weight and adjusted until the footwear bottom
sits flat on the angled face of the wedge with approximately 4 mm of the wedge extending beyond the
foremost contact point of the forepart with the face of the wedge.

For the flat test mode, the footwear shall be fitted onto the mechanical foot (4.1.3) or the manufacturer's
shoemaking last (4.1.2). The mechanical foot shall be orientated such that the longitudinal axis of the
mechanical foot is aligned parallel to the direction of sliding movement. The footwear shall be fitted
onto the mechanical foot with the heel contact plate placed centrally in the heel seat with a small
gap between the back edge and sides of the insole and with the forepart contact plate positioned
approximately central to the forepart (see Figure 9). If using a manufacturer's shoemaking last (4.1.2)
in place of the mechanical foot (4.1.3), then the last shall be aligned such that the footwear attains the
same orientation of the outsole tread pattern relative to the direction of slip as would be achieved if
using a mechanical foot (4.1.3).
6.2.3 The normal force (3.1) for footwear of European size 40 (UK size 6,5, Mondopoint 255) and above
shall be (500 ± 25) N. For footwear of European size below 40, the normal force shall be (400 ± 20) N.
Once achieved, the required normal force shall be maintained throughout the measurement period of the
test (6.2.6).
In the heel test mode, the line of action of the normal force shall be aligned approximately through the
rear edge of the heel-floor contact area determined under the weight of the shoe, last and mounting [see
Figure 3a)]. No additional force should be applied.
In the forepart test mode, the line of action of the normal force shall be aligned through a point at
the approximate centre of the forepart region or approximately one third of the length of the outsole
measured back from the end of the toe (see Figure 3b).
In the flat mode, the mechanical foot (4.1.3) determines the line of action of the normal force (see Figure
3c). If the manufacturer's shoemaking last (4.1.2) is used, the line of action of the normal force shall be
through the approximate mid-point of the length of the footwear.
6.2.4 The static contact time shall be a maximum of 1,0 s from an initial contact force of 50 N to
achieving full normal force and initiation of sliding movement. Sliding movement shall start within 0,3 s
of achieving the full normal force (see Figure 6).
6.2.5 The sliding velocity during the measurement period shall be (0,3 ± 0,03) m/s.
6.2.6 The mean frictional force shall be measured over the measurement period between (0,30 ± 0,02) s
and (0,60 ± 0,02) s after the start of sliding movement, during which the full normal force (6.2.3) and
sliding speed is maintained (see Figure 6).

7.1.3 Wash the outsole (all parts that will be in contact with the surface during the test, including the
heel and forepart) using an ethanol solution (4.13) and scrubbing with a clean medium stiff brush. Rinse
with demineralized water. Dry using clean, dry compressed air and then at ambient temperature.
Certain types of polyurethane (PU) soling may also be tested after solvent wiping the surface in order
to remove mould release agent which may be present (a greasy residue transferred to the outsole from
the inside of the metal mould). Solvent wiping is mainly applicable to reaction moulded PU outsoles
which have been direct moulded to the shoe upper. Such outsoles shall first be tested after washing
using an ethanol solution (4.13) and then again not less than 16 hours after thoroughly wiping with
grease-free cotton wool wetted with propanone (4.14). At the end of 16 hours and before the test, the
outsole shall be again washed using ethanol solution (4.13).
7.1.4 Preparation of the outsole: the following abrasion shall be carried out with the footwear mounted
on an appropriate last.
Prepare the outsole (all parts that will be in contact with the surface during the test, including the
heel and forepart) of the footwear by lightly abrading it with silicon carbide paper affixed to a rigid
block (4.9). No significant additional pressure shall be applied other than by the weight of the block (see
Figure 7). Use linear or circular abrasion but with the final abrasion being linear and in the direction
parallel to the direction of sliding movement in the test. Only superficial abrasion shall be applied that
does not significantly change the tread pattern or the
