4 Types and minimum area requirements
4.1 Types
The enhanced visibility equipment is grouped into three types based on the foreseeable conditions of
use:
— Type A
Equipment worn by users where the risk of not being seen exists only at daylight conditions. This
equipment uses only the fluorescent material as enhanced visibility component.
— Type B
Equipment worn by users where risk of not being seen exists only at dark conditions. This
equipment uses only the retroreflective material as enhanced visibility component.
Type B is subdivided in 3 levels, as below. The classification depends on the total area worn or on
placement of the device on user’s torso and limbs:
— Type B1 includes free hanging retroreflective devices only; these devices are designed for
movement recognition.
— Type B2 includes retroreflective devices or retroreflective material either temporarily or
permanently placed on limbs only; these products are designed for movement recognition. As a
minimum, the retroreflective material shall be positioned on the limbs as a separate removable
device or shall be incorporated into clothing design on a permanent basis as a retroreflective
element.
— Type B3 includes retroreflective material placed on torso or torso and limbs. These products
are designed for form recognition, or form and movement recognition. Type B3 items shall not
be a combination of permanently attached reflective material and removable reflective devices.
NOTE 1 Additional retroreflective or combined-performance materials can be incorporated into garments.
— Type AB
Equipment worn by users where risk of not being seen exists during daylight, twilight and dark
conditions. This equipment uses the fluorescent as well as the retroreflective and/or combined
performance materials as enhanced visibility components.
!There are two types of AB equipment. Both types cover the risk of not being seen during
daylight and dark conditions. Type AB2 is designed for movement recognition in dark conditions
and follows the requirements of Type A and B2. Type AB3 is intended for form recognition in dark
conditions and follows the requirements of Type A and Type B3."
Table 1 shows the different types.

NOTE 2 See Annex B for examples and drawings.
For each type, the relevant material requirements in Clause 6 shall be fulfilled in accordance to Clause 7.
4.2 Minimum area requirements
Each type shall have minimum areas of materials incorporated in the garment or equipment in
accordance with:

If the height range (interval figures as described in EN ISO 13688:2013 includes 140 cm (e.g. garment
designed for height range from 138 cm to 142 cm), then the requirements as stated in the column “h > 140”
apply.
"
Additional fluorescent, retroreflective or combined-performance materials may be incorporated into
garments.
NOTE The area of visibility material shown in Table 3 cannot be reduced below the minimum requirements
by the application of logos, lettering, labels, etc.
5 Design requirements
5.1 Size designation
The size designation for garments shall be in accordance with the requirements of
1)
!EN ISO 13688:2013 ".
5.2 Type A
5.2.1 General
Type A garments (including partial body protective clothing) shall in their design use at least the
minimum amount of fluorescent material according to Table 3.
NOTE 1 Protective clothing items are worn to cover one or more parts of the body, examples of partial body
protection are sleeves, aprons and chaps.
The areas shall be measured on the smallest garment size intended to be supplied, in each of the two
height ranges specified in Table 3, with all fasteners adjusted to the smallest configuration possible and
with the garment laying flat on a table.
Fluorescent material areas covered by any logos, lettering, labels etc., are not counted towards the total
area.
NOTE 2 Conspicuity is best achieved by having well defined areas of fluorescent material. Fragmented or highly
patterned areas are unsuitable.
5.2.2 Visibility from all sides
Type A garments shall be made up of fluorescent material on all sides to ensure 360° visibility (visibility
from all sides). For upper body garments fluorescent material shall be evenly distributed around the
torso and/or upper arms and/or limbs, if any.
For lower body garments, fluorescent material shall be evenly distributed around the legs.
Visibility from all sides shall be reached as follows:
— not less than 40 % of the minimum required amount of fluorescent material specified in Table 3 is
present on both the front and the back when laid flat, and
— not less than 10 % of the minimum required amount of fluorescent material specified in Table 3 is
present on both the right and left sides when laid flat on the back (respectively on the front).
Annexes C and D show examples of designs and how to measure visibility from all sides.
5.3 Type B
5.3.1 General
These garments or devices shall in their design use at least the minimum amount of retroreflective
material according to Table 2 or Table 3.
5.3.2 Type B1 – Free hanging devices
The devices shall be removable.
The total area of the devices in use shall meet the requirements in Table 2.
A Type B1 device shall be retroreflective from both sides.
2 2
Its optical active area shall be a minimum 15 cm per side. The total area shall be maximum 50 cm per
side. In order to achieve 360° visibility (visibility from all sides) at least two devices shall be used, these
shall be used on the left and the right side of the torso. This shall be specified in the user information.
The device shall be flat and its maximum thickness shall be 10 mm.
The means of attachment (string, ribbon, cord, spiral, etc.) shall be a minimum 10 cm, in length between
the points of attachment on the garment and that on the reflector to enable free movement of the device
around its vertical axis and allow a pendulum effect.
NOTE Consider additional requirements applicable for children’s products.
5.3.3 Type B2 – Equipment for limbs
The minimum area of retroreflective material shall fulfil the requirements in Table 2.
To ensure 360° visibility (visibility from all sides), one or more devices shall be applied to each upper
and/or each lower limb.
When retroreflective material is applied to a garment it shall also be positioned to achieve 360°
visibility (visibility from all sides). The material shall be placed on the limbs so as to ensure a minimum
width of 20 mm encircling each limb.
Any gap in the lengthwise continuity of the retroreflective material shall not be greater than 50 mm,
measured parallel to the direction of the material, and the total of such gaps shall not be greater than
50 mm around the limbs. Any offset not greater than the width of the material plus 5 mm is allowed.
Additionally, separate retroreflective elements may form part of an applied design in conjunction with
the above. The retroreflective elements shall have a minimum area of 25 cm each.
In the case of B2 garments covering upper and lower limbs, the retroreflective material can be applied
on the upper limbs only, on the lower limbs only or on both the upper and lower limbs. In the latter
case, the minimum amount of Table 2 shall be used for upper limbs and also for the lower limbs.
NOTE An example of a B2 garment is shown in Annex E.
5.3.4 Type B3 – Equipment for the torso or the torso and limbs
The minimum area of retroreflective material shall fulfil the requirements in Table 3. Garments and
devices shall be measured flat and in their smallest configuration.
Retroreflective material shall be placed on the torso so as to ensure a minimum width of 20 mm
encircling the torso. Alternatively, retroreflective materials may be placed to encircle the upper arms.
If a B3 garment covers limbs below the elbows or knees, then retroreflective material on the limbs is
required. In this case, Type B2 requirements (see 5.3.3) for the limbs shall be fulfilled whilst the
remainder of the material shall be placed on the torso. !It is not necessary for a minimum 20 mm
wide band to be applied on the limbs in this case, retroreflect
