Overview

EN ISO 13287:2019 - Personal protective equipment - Footwear - Test method for slip resistance (ISO 13287:2019) specifies a laboratory test method to assess the slip resistance of PPE footwear and related soling components. The standard defines how to measure the coefficient of friction (CoF) between footwear and test surfaces, required apparatus, sampling and conditioning, test modes and reporting. Footwear marketed as “slip resistant” is treated as personal protective equipment under this standard. It is not applicable to special-purpose footwear fitted with spikes, metal studs or similar.

Key topics and technical requirements

• Scope and status: Third edition (2019); endorsed by CEN as EN ISO 13287:2019 and supersedes the 2012 edition.
• Fundamental principles: Measurement of frictional force and normal force to calculate CoF; terms such as static contact time and measurement period are defined.
• Apparatus:
  • Standard shoemaking lasts or a specified mechanical foot to mount samples (Annex A).
  • Mechanisms to apply the normal force and induce relative motion.
  • Force measurement devices with ±2% accuracy for both normal and frictional forces.
  • Specified test surfaces: stainless steel plate (prepared to a roughness Rz ≈ 1.6–2.5 µm), pressed ceramic tile (Eurotile 2) (Annex B), and other characterized floors.
  • Reference slider (Slider 96) or equivalent for calibration (Annex C).
• Sampling & conditioning: Requires representative left and right samples; conditioning procedures (conditioning time reduced to 24 h in this edition).
• Test modes and calibration: Defines test speeds, contact conditions, curved outsole handling, and calibration procedures for test surfaces and tiles.
• Reporting: Specifies required test report information including CoF values, test surface, footwear preparation and any deviations.

Practical applications

• Product evaluation and R&D: footwear designers and manufacturers use EN ISO 13287:2019 during development to quantify slip performance of outsoles and sole units.
• Certification and compliance: test laboratories and conformity assessment bodies rely on the method for supplier claims of “slip resistance.”
• Procurement and safety: safety officers, specifiers and buyers use CoF data to compare PPE footwear for workplaces with slip hazards (wet, oily or contaminated floors).
• Quality control: production and QA teams use the method to monitor consistency of soling materials and manufacturing processes.

Who uses this standard

• PPE footwear manufacturers and designers
• Accredited testing laboratories and certification bodies
• Occupational health & safety professionals and procurement teams
• Standards organizations and regulatory authorities

Related standards

• ISO 4287 - surface texture/profile (referenced for steel plate roughness)
• ISO 4662 - rubber rebound resilience (referenced)
• Annexes in EN ISO 13287:2019: A (last/mechanical foot), B (Eurotile 2 specification), C (calibration procedure)

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 ;

— uncertainty and conformity assessment as given in ISO/IEC Guide 98-4 ;
[5]
— 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.
