The measurement of the minimum initial coefficient of retroreflection R shall be made using CIE

illuminant A (EN ISO 11664-2) in accordance with the procedures defined in CIE 54.2:2001.

The test measurements shall be performed on a production representative sample of retroreflective

material measuring an area of at least 30 cm mounted according to the manufacturer's instructions

onto a flat support sheet.

SIST EN 13422:2020
EN 13422:2019 (E)

5.2.2 Determination of the coefficient of retroreflected luminance R for retroreflective traffic

cones or traffic cylinders

The coefficient of retroreflected luminance R shall be measured using the apparatus shown in Figure 1.

The traffic cone or traffic cylinder to be tested shall be a representative manufacturing sample. A traffic

cone shall be mounted on a support such that the base plate is aligned horizontally. A traffic cylinder

shall be mounted with the cylinder body in a vertical position in the manner required by the

manufacturer. The test shall be repeated from 4 sides, by rotating the cone around its axis by 90° steps

(typically starting with the overlap of the retroreflective material as 0°). All 4 measurements shall be

evaluated.

Figure 1 — Side view of the equipment for testing the coefficient of retroreflected luminance

The distance between the test sample, traffic cone or traffic cylinder, and the photometer/ light source

arrangement shall be not less than 10 000 mm. The photometer shall have an aperture of between 2'

and 6' (minutes of arc), and the aperture of the light source shall not exceed 10' (minutes of arc), in both

cases as seen from the location of the test sample. The observation angle α, i.e. the angle between the

photometer and the light source as seen from the location of the test sample, is adjusted to the desired

value. The light source shall have a spectral distribution according to CIE standard illuminant A (EN ISO

11664-2:2011) and the photometer shall have spectral sensitivity according to the V(λ) distribution.

Refer to CIE publication No. 54, including suitable methods of calibration and suppression of ambient

signal.

A measurement field on the test sample is defined by means of a circular aperture of 40 mm in a mask.

The distance between mask and test sample should be minimized. For traffic cones, position the mask

tilted back (following the angle of the cone) and place it directly on the cone surface. In case of traffic

cylinders, the mask shall be placed in a vertical position just in front of the test sample.

Alternatively, when the photometer has optics to define a circular measurement field on the test

sample, as with a luminance meter, the mask may be omitted. The diameter of the measured field shall

not exceed 20 % of the diameter of the test sample at the elevation on the test sample where the

measurement takes place.

The measurement field is placed on the vertical centre line of the test sample at such a height that a

single colour of retroreflective surface is fully included within the measurement field.

---------------------- Page: 12 ----------------------
SIST EN 13422:2020
EN 13422:2019 (E)

When using a mask, the intensity of retroreflected light I through the aperture of the mask is measured

by means of the photometer and used to derive the luminance L by means of L = I/(A × cos β ), where A

is the area of the aperture and β is the angle between the sides of the cone body and the cone's vertical

axis. When the photometer defines the measurement field, the luminance L is measured directly.

Measurements shall be performed for each colour of retroreflective surface on the test sample.

In either case, the illuminance E at the location of the test sample on a plane perpendicular to the

direction of illumination is measured, and the coefficient of retroreflected luminance R is determined

by means of its definition:
−2 −1
RL = L/ E⊥ in cd⋅m ⋅lx
5.2.3 Determination of relative distribution of retroreflective performance

Using the same method described in 5.2.2, set the observation angle at 20’, the measurement field is

moved in ten uniform steps from the vertical centre line of the test sample to each side outwards to the

left or to the right edge of the retroreflective surface of the test sample. The measurement field is moved

by moving the mask, when a mask is used to define the measurement field, or by aiming the

photometer, when the photometer is a luminance meter used to define the measurement field. The

measurement fields may overlap. The measurement field should not extend beyond the edge of the

retroreflective surface. Refer to Figures 2 and 3.

The light source remains in a fixed position. For all locations of the measurement field, a single colour of

retroreflective surface shall be fully included within the measurement field.

5.3 Test for determination of stability of traffic cones

The equipment illustrated in Figure 4 shall be used to determine the stability of traffic cones.

The test sample shall be conditioned at (20 ± 2) °C for two hours before testing.

A horizontal reference surface is provided with a step having a vertical height of (12 ± 2) mm.

The test sample cone is placed on the reference surface so that part of the base plate is in contact with

the vertical face of the step.

The equipment may employ a pulley system and weight as illustrated or a calibrated force meter as

suitable. In both cases, movement of the top of the traffic cone of at least 1,5 H of the test sample shall

be provided in the arrangement.

A horizontal force as given in Table 12 is applied to the top of the traffic cone parallel to the reference

surface. The force exerted shall be appropriate to the weight class of the test sample according to

Table 1.

Traffic cones and traffic cylinders shall be conditioned for a minimum of 2 h at the required

temperatures and the test completed within one minute of removing the traffic cone or traffic cylinder

from its conditioning environment.

twisting. The wires shall have a maximum thickness of 1 mm and the ball shall have a mass of

(0,9 ± 0,045) kg. It shall move in an arc having a radius R of (1 750 ± 10) mm. The impact point of the

steel ball on the sample shall be vertically beneath the mid-point between the ball suspension points at

a distance of H/3 to H/2 above the reference surface.

Before the impact test, the position of the highest R at the height of the intended impact point shall be

found by turning the test sample round its vertical axis using the test equipment described in 5.2.2.

Then the test sample conditioned at a temperature of (–18 ± 2) °C shall be secured on the test area in

such a way that the steel ball of the test equipment will strike the test sample in the area where the

highest coefficient of retroreflection was found. The steel ball shall be released from its highest point.

The test shall be performed separately on each colour present in the retroreflective surfaces.

5.5 Drop test for traffic cones

The drop test shall be performed on test samples conditioned at a temperature of (32 ± 2) °C and at

(−18 ± 2) °C. Traffic cones shall be conditioned for a minimum of 2 h and the test completed within one

minute of removing the traffic cone from its conditioning environment.

The test sample shall be suspended with its vertical axis horizontal. The lowest part of the test sample

in this position shall be (1 500 ± 5) mm above a fixed horizontal reference surface. The test sample shall

then be dropped onto the reference surface.

5.6 Measurement of coefficient of retroreflection of wet retroreflective surfaces

5.6.1 Principle

To measure the coefficient of retroreflection of wet retroreflective traffic cones and cylinders by the

procedures and instructions given in 5.2.1 or 5.2.2.
5.6.2 Apparatus

The apparatus consists of a means of spraying distilled water onto the retroreflective surface. The

apparatus is shown in Figure 7.
