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 13287 was prepared by the European Committee for Standardization (CEN) Technical Committee

CEN/TC 161, Foot and leg protectors, in collaboration with ISO Technical Committee ISO/TC 94, Personal

safety — Protective clothing and equipment, Subcommittee SC 3, Foot protection, in accordance with the

agreement on technical cooperation between ISO and CEN (Vienna Agreement).

This second edition cancels and replaces the first edition (ISO 13287:2006), which has been restructured for

ease of use, more precisely specified in many areas and technically revised. The main technical revisions are:

— Subclause 4.1.2 and Clause 6 allow the use of the footwear manufacturer’s shoemaking last;

— Subclauses 4.5 and 8.9 and Annexes B and D introduce ceramic tile Eurotile 2 as a replacement for

Eurotile 1 (Annex C);
— Subclause 6.2.4 changes a timing parameter in the test;

— Subclauses 7.1.6 and 7.2.4 limit the amount of use of footwear and floor specimens before requiring

re-preparation;

— Annex E has been added, which amends and supersedes ISO 20344:2011, 5.11.2, including a technical

change in E.4.6.

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 from all

10 locations shall be for R between 1,6 μm and 2,5 µm.

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 succession of reducing grit sizes. The polishing

direction of each operation shall be perpendicular to the preceding operation with the final direction being in the

test direction. The preparation shall continue until the roughness parameter falls within the above specifications.

NOTE 2 Grit sizes 100 to 600 can be suitable.

4.5 Pressed ceramic tile floor, as specified in either Annex C or Annex D. The tiles shall not be modified in

any way, for example, by mechanical or chemical treatment.

4.6 Other floors, for example, wood, concrete, stone, polymeric flooring. The floor shall be characterized by

determining the coefficient of friction in accordance with Annex E.

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 as a suitable means of setting the contact angle. The tip of the

wedge shall be truncated so that it is no more than 0,5 mm in height as judged by a graduated eyepiece. 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 1a)]. For the forepart test, the length of the wedge shall be sufficient

to support the whole of the heel and forepart of the shoe [see Figure 1b)].

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.

4.13 Ethanol solution, containing a mass fraction of (50 ± 5) % ethanol GPR (CAS 64-17-5), which may be

prepared from industrial methylated spirits GPR containing minimum 90 % ethanol, in demineralized water.

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.

NOTE The uncertainty of measurement may be assessed by one of the two following approaches:

— a statistical method, e.g. that given in ISO 5725-2;
— a mathematical method, e.g. that given in ENV 13005.
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 48 h.

If necessary, the sample may be removed from this standard atmosphere provided that its temperature is

© ISO 2012 – All rights reserved 3
---------------------- Page: 13 ----------------------
SIST EN ISO 13287:2013
ISO 13287:2012(E)

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.
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 1):

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 2), shall be aligned parallel to the direction of sliding

movement (see Figure 2).

In the heel test mode the footwear moves forward in the heel to toe direction. The contact angle between the

bottom of the heel and the floor shall be (7,0 ± 0,5)° [see Figure 1a)], determined using a rigid wedge (4.10)

placed on the floor. 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 2 mm

to 3 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 1b)] 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

2mm to 3 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 3). 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.

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 1a)]. No

additional force should be applied.

---------------------- Page: 14 ----------------------
SIST EN ISO 13287:2013
ISO 13287:2012(E)

In the forepart test mode, the line of action of the normal force shall be aligned through a point approximately

onethird of the length of the outsole measured back from the end of the toe [see Figure 1b)].

In the flat mode, the mechanical foot (4.1.3) determines the line of action of the normal force [see Figure 1c)].

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 4).

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 4).
