Annex A
(normative)
Barefoot Ramp Test
A.1 Principle
Two bare-foot test persons are used to determine the acceptance angle, after the pedestrian surface
material being tested has been continuously coated with water containing a wetting agent. The test
persons, each in turn, facing downhill and with an upright posture, move forwards and backwards over
the test surface, as they increase their angle of inclination, until the safe limit of walking is reached and
a slip occurs. The mean acceptance angle obtained is used to express the degree of slip resistance.
Subjective influences on the acceptance angle are limited by means of a calibration procedure.
A.2 Test equipment
A.2.1 Test apparatus
The test device (Figure A.1) is a level and torsion-free platform of approximately 600 mm width and
2 000 mm length which can be adjusted longitudinally as a continuous movement to gradients from 0°
to approximately 45°. The lifting stroke is controlled by the test person. An angle indicator on the test
device shall show the platform tilt away from the horizontal plane at an accuracy of ± 0,2°. The test
apparatus shall be rigid such that the angle does not vary by more than ± 0,5° during the walking. The
display of the angle measurement system shall be fixed in such a way that the test person cannot read it
during the test. The test person is safeguarded by railings along the sides and protected from falling by
a safety harness which shall not cause a hindrance to the test person when walking on the pedestrian
surface material under test.

A.2.2 Test surface
The test surface area shall be approximately 100 cm × 50 cm. The test surface shall be clean. The test
surface shall be either self-supporting, or securely mounted on a suitable flat surface.
If the slip resistance differs depending on the direction of walking, then it will be necessary to
determine the direction of lowest slip resistance.
A.2.3 Contaminant
Aqueous solution of Dehypon LS45 (CAS-No. 68439-51-0) in a concentration of 1 g/l (aqueous solution:
0,1 % Dehypon LS45 in water) shall be used as the contaminant. Prior to and during testing the aqueous
solution shall be applied at (6,0 ± 1,0) l/min using appropriate jets so as to form a largely uniform spray
of contaminant across the test specimen. The temperature range of the solution shall be in between
29,0 ± 2,0 °C.
The contaminant shall run in an open circle (no recirculation).

A.3 Calibration
A.3.1 General
The inclination of the inclinable walkway surface shall be calibrated annually and checked periodically.
Verification of the data produced by test persons shall be undertaken daily prior to testing. The latter
shall be achieved by use of an appropriate set of standardized surfaces. The calibration processes as
specified below shall be used to select and familiarise the test persons.
A.3.2 Validation of the test person
Three standard surfaces, St-A, St-B and St-C, are used for the calibration process. The acceptance angle
(α) of these surfaces are given in Table A.1 and are specified as acceptance angles α , α and α
S,St-A S,St-B S,St-C
of the three standard surfaces.
On the same day, but prior to testing the test surfaces, each test person (j) shall walk on each standard
surface (i = St-A, St-B and St-C) three times (see A.4) and the mean calibration (C) values α , α
C,St-A,j C,St-B,j
and α shall be determined.
C,St-C,j
∆=αα−α
Each individual correction value (i = St-A, St-B and St-C) of the calibration prior to
ij, S ,i C ,,ij
testing shall be calculated and gives ∆∆αα, and∆α .
St−−A,,j St B j St−C , j
Each of the individual correction values shall be less than the corresponding critical differences CrD
95
that are given in Table A.1, i.e. ||∆≤α CrD . If one of the absolute values is greater, the test person in
ij, 95
question shall be excluded from the test and replaced by another test person for that day.
Table A.1 — Acceptance angle and critical difference values of the three standard surfaces
Standard surface α CrD
S,i 95
St-A 11,5° 2,1°
St-B 18,5° 2,1°
St-C 23,9° 2,1°
NOTE The critical difference of CrD indicates the spreading of measured values during measurements on
95
the same object at various test locations, or coincidental deviations during repeated measurements at the same
test location.
The critical differences of CrD are determined for the three standard surfaces for a significance level of
95
95 % from the comparison and repetition limits according to ISO 5725-2 or ISO 5725-5.

A.4 Test procedure
a) The test surface (see A.2.2) shall be clean.
b) The test person shall put on the harness (see A.2.1). The test person shall then attach to the fall
arrest system (see A.2.1).
c) The test person shall mount the ramp (which shall be set to the horizontal position) so as to stand
on the test surface.
d) Application of the aqueos Dehypon-solution
e) Facing down the ramp and looking at their feet, the test person, using a half-step gait, shall take a
minimum of four steps down the test surface (walking forwards), and then take half-steps up the
test surface (walking backwards) to return to their starting position. The test person shall walk up
and down the test surface twice before raising the ramp by a small amount. This continues until a
slip occurs.
f) It is essential to maintain a rhythm of about 144 half steps per minute. A metronome or similar
should be used to keep pace.
NOTE Above a ramp angle of 15°, the pace is less important.
g) Once a slip occurs the walk shall be repeated at the angle of slip and if a further slip occurs then this
angle is recorded.
h) If there is no second slip the test is continued, raising the angle by a small amount until two slips
occur at the same angle.
i) Record the angle, α rounded to the nearest 0,2°.
barefoot
j) Repeat the procedure from the horizontal two more times and record all three angles.

Introduction
This document describes the most commonly used test methods in Europe for the determination of the
slip resistance of floorings in the most commonly encountered situations in which pedestrians walk.
The method in Annex A describes the test method based on the ramp with contaminant water and
operator barefoot.
The method in Annex B describes the test method based on the ramp with contaminant oil and operator
wearing specified shoes.
NOTE The contaminant oil is used only to make the test more sensitive.
The method in Annex C describes the test method based on the pendulum in dry and wet conditions
using specified rubber sliders. This method can be used in situ.
The method in Annex D describes the test method based on the tribometer in dry and wet conditions
using specified rubber sliders. This method can be used in situ.
The tests described in Annexes A and B are laboratory tests. The tests described in Annexes C and D are
laboratory and in situ tests. It is recommended to use Annexes A to D in the situations described as
follows:
The method in Annex A: Floorings in wet conditions where the pedestrian is barefoot.
The method in Annex B, C and D: Floorings in private and/or public and/or work areas in wet and/or
dry conditions where the pedestrian is wearing shoes.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
pedestrian surface
surface which is designed for people to walk upon
3.2
acceptance angle
lowest angle of the inclined ramp at which the test person reaches the limit of safe walking when
slipping occurs
3.3
contaminant
material on the surface of the surface which is not an inherent part of the surface and which can affect
the frictional properties of that surface

pedestrian surface excluding road surfaces and sports surfaces
3.5
friction
resistance to relative motion between two bodies in contact, e.g. the test slider or the footwear sole and
the pedestrian surface
Note 1 to entry: The frictional force is the force acting tangentially in the contact area.
3.6
slip
loss of traction which can cause the test persons to lose their footing
3.7
slip resistance
measure of dynamic friction between two surfaces in contact and which may or may not be in the
presence of a specified contaminant
Note 1 to entry: The frictional force opposing movement of an object across a surface, usually with reference to
the sole (including the heel) of a shoe or to the barefoot contact area on a floor. Slip resistance of a pedestrian
surface is the property of the surface which limits the relative sliding movement.

pendulum test value
PTV
standardised value of the slip resistance as measure of the friction between the slider and the test
surface obtained with the pendulum friction tester which incorporates a slider manufactured of rubber

3.12
sliding friction coefficient for surfaces
μ
quotient of the horizontal frictional force and the vertically acting force between the slider and the
horizontal surface during movement at a constant speed

Annex A
(normative)
Barefoot Ramp Test
A.1 Principle
Two bare-foot test persons are used to determine the acceptance angle, after the pedestrian surface
material being tested has been continuously coated with water containing a wetting agent. The test
persons, each in turn, facing downhill and with an upright posture, move forwards and backwards over
the test surface, as they increase their angle of inclination, until the safe limit of walking is reached and
a slip occurs. The mean acceptance angle obtained is used to express the degree of slip resistance.
Subjective influences on the acceptance angle are limited by means of a calibration procedure.
A.2 Test equipment
A.2.1 Test apparatus
The test device (Figure A.1) is a level and torsion-free platform of approximately 600 mm width and
2 000 mm length which can be adjusted longitudinally as a continuous movement to gradients from 0°
to approximately 45°. The lifting stroke is controlled by the test person. An angle indicator on the test
device shall show the platform tilt away from the horizontal plane at an accuracy of ± 0,2°. The test
apparatus shall be rigid such that the angle does not vary by more than ± 0,5° during the walking. The
display of the angle measurement system shall be fixed in such a way that the test person cannot read it
during the test. The test person is safeguarded by railings along the sides and protected from falling by
a safety harness which shall not cause a hindrance to the test person when walking on the test floor.

A.2.2 Test surface
The test surface area shall be approximately 100 cm × 50 cm. The test surface shall be clean. The test
surface shall be either self-supporting, or securely mounted on a suitable flat surface.
If the slip resistance differs depending on the direction of walking, then it will be necessary to
determine the direction of lowest slip resistance.
A.2.3 Contaminant
Aqueous solution of Dehypon LS45 (CAS-No. 68439-51-0) in a concentration of 1 g/l (aqueous solution:
0,1 % Dehypon LS45 in water) shall be used as the contaminant. Prior to and during testing the aqueous
solution shall be applied at (6,0 ± 1,0) l/min using appropriate jets so as to form a largely uniform spray
