UNE-EN 17353:2020+A1:2025. PROTECTIVE CLOTHING. ENHANCED VISIBILITY EQUIPMENT FOR MEDIUM RISK SITUATIONS. REQUIREMENTS AND TEST METHODS. Equivalence with EN 17353:2020 A1:2025.
This standard specifies visibility requirements for garments or devices that are capable of visibly signaling the wearer’s presence.
Enhanced visibility equipment is intended to provide visibility to the user in medium-risk situations, under any daylight conditions or under illumination from vehicle lights or reflectors in the dark.
Requirements include color and retroreflection, as well as the minimum area and location for protective materials.
This standard does not apply to situations with a risk of high visibility (see EN ISO 20471); visible head, hand and foot equipment; equipment with integrated active light (e.g. LEDs); low-risk visibility situations.
TYPES DEPENDING ON USE:
There are 3 types depending on the use:
Type A: Equipment for users to be seen in daylight conditions. These teams use only fluorescent materials as a component.
Type B: Equipment for users to be seen in dark conditions. These equipment use retroreflective materials as a component of improved visibility. This type has 3 levels depending on the area or location of the device on the torso and limbs:
Type B1: Includes only pendant retroreflector devices designed to be visible in motion.
Type B2: includes retroreflective devices or retroreflective material located on the extremities temporarily or permanently designed for visibility in motion. At a minimum, the retroreflective material must be positioned on the limbs as removable material or incorporated into the garment permanently.
Type B3: Includes retroreflective material on the torso and limbs designed to be visible in static and motion. A combination of removable and permanent materials cannot be used in this type.
Type AB: Equipment for users where the risk of not being seen may occur during the day, night or twilight. This equipment uses fluorescent materials and retroreflectors and their combinations as a component of improved visibility. There are two types in this category:
Type AB2: to recognize the user in motion in dark conditions with the requirements of type A and B2.
Type AB3: to recognize the user in static conditions in dark conditions with the requirements of type A and B3.

DESIGN
Size designation according to EN ISO 13688
TYPE A GARMENTS:
They must have a minimum amount of fluorescent material indicated in the table. These areas will be measured in the smallest garment size supplied in each of the two height ranges.
The fluorescent material covered by logos, letters, labels… It will not be used to determine the minimum area required.
Type A garments must provide 360 º visibility through the fluorescent material. For upper body garments, fluorescent material may be distributed around the torso and/or upper arms and/or extremities. For lower body garments, the fluorescent material should be distributed around the legs.
Visibility from anywhere shall be achieved as follows: At least 40 % of the minimum amount of fluorescent material described in the table shall be present on both sides of the garment and at least 10 % of the minimum amount required in the table shall be present on both right and left sides, when the garment is placed face up.
TYPE B GARMENTS:
They must have the minimum amount of retroreflective fabric specified in the table.
Type B1 Hanging Devices:
Devices must be detachable and must have the minimum required area specified in the table.
The device must be retroreflective on both sides. The active optical area should be at least 15 cm on each side. The maximum total area should be 50 cm2 on each side. For visibility to be 360 º, at least 2 devices must be worn on the left and right of the torso.
The device must be flat and with a maximum thickness of 10 mm.
The means of attachment (ropes, cords, straps, etc.) must have a minimum length of 10 cm between the attachment points of the garment and the reflector, allowing the device to move freely around the vertical axis and allowing a pendulum effect.
Type B2 Limb Equipment:
The minimum retroreflective area must comply with what is specified in the table.
To ensure 360 º visibility, one or more devices must be located on the arms and/or on each leg.
If the retroreflective material is part of the garment, it must be positioned to ensure visibility from all sides (360 º). The material located on the limbs must be at least 20 cm wide and must surround each limb.
Any longitudinal separation of the retroreflective material may not exceed 50 mm measured parallel to the direction of the material, and the total number of separations may not exceed 50 mm around the extremities.
The retroreflective elements must have a minimum area of 25 cm2 each.
In the event that B2 garments cover both the upper and lower extremities, the retroreflective material can be applied only to the arms, legs or arms and legs. If applied to the legs and arms, the minimum amount described in the table should be located on the arms and also on the legs.
Type B3 Torso & Torso & Limb Equipment:
The minimum required area of retroreflective material must meet the requirements of the table. Garments and equipment will be used for measurement in the smallest size.
The retroreflective material must be located on the torso ensuring a minimum width of 20 mm surrounding the torso. Alternatively, the material can also be applied to surround the upper arms.
If the garment covers the legs below the knees or the arms below the elbows, retroreflective material is required and must meet the requirements of type B2 for the extremities.
The retroreflective elements must have a minimum area of 25 cm2 each.
Visibility from all sides must comply with the following:
-At least 40 % of the minimum amount of retroreflective material must be present at the front and rear when laid flat.
-At least 10 % of the minimum amount of retroreflective material must be present on the right and left sides when placed flat on the back.
Any longitudinal gap between the retroreflective material shall not exceed 50 mm measured in parallel to the direction of the material and the total gaps shall not exceed 100 mm around the torso.
In the event that the garments cover the torso and upper and lower extremities, the retroreflective material must be located on the torso and arms or on the torso and legs or torso, legs and arms. If it is located in the torso, legs and arms, these must comply with the minimum area of the board.
Type AB:
These garments have in their design a minimum amount of fluorescent and retroreflective material or an appropriate combination following the requirements of the table. The design requirements for these garments must follow the same indications regarding the distribution of fluorescent material as type A. For retroreflective material, the same indications must be followed as type B2.
The combined performance material shall be used in such a way as to maintain the width of at least 20 mm. In these cases, the area of fluorescent material may be reduced by the amount of combined material used.
