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."

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

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.

5.1 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.

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

EN 17353:2020+A1:2025は、中リスク状況における強化視認性装備に関する標準仕様を提供しています。この文書の主な目的は、視覚的に使用者の存在を示すことができる衣料品またはデバイスの要件を明確にすることです。特に、この標準は、日光条件下および車両のヘッドライトや捜索灯による照明下での着用者の目立ちを確保することに重点を置いています。 この基準の大きな強みは、色彩および再帰反射に関するパフォーマンス要件を含み、保護具の材料の最小面積や配置についても具体的に規定している点です。これにより、使用者が安全に視認されることが保証され、特に中リスクの環境での事故を防ぐための重要な役割を果たします。 なお、EN 17353は高リスク状況における高視認性装備に適用されるものではなく、これに関してはEN ISO 20471が該当します。また、頭部、手、足用の特定の視認性装備（ヘルメット、グローブ、シューズなど）や、アクティブな照明を統合した装備（LEDなど）、低リスク状況における視認性については適用されないことも明確にされています。 全体として、EN 17353:2020+A1:2025は、強化視認性装備に関する詳細かつ実用的な基準を提供しており、中リスク状況の安全性向上に寄与する内容となっています。これは、関係者が安全基準を遵守し、適切な保護具を選択するための貴重な指針となるでしょう。
The EN 17353:2020+A1:2025 standard offers a comprehensive framework for protective clothing designed to enhance visibility for users in medium risk situations. Its scope is clearly delineated, focusing on garments and devices that visually signal the presence of the wearer under various daylight conditions and through vehicle headlights or searchlights at night. This specificity ensures that users in environments with medium risk can be adequately protected. One of the standard's significant strengths lies in its detailed performance requirements. It specifies criteria for colour and retroreflection, which are crucial for ensuring that the enhanced visibility equipment maintains its effectiveness in different lighting conditions. The prescribed minimum areas for reflective materials and their strategic placement on the garments enhance the overall safety and visibility of the wearer. This ensures that individuals are noticeable and can be safely identified in potentially hazardous situations. The standard's relevance is underscored by its targeted application; it explicitly excludes high visibility equipment for high-risk situations, which is governed by EN ISO 20471. This allows stakeholders to easily differentiate between standards based on risk levels, thus streamlining compliance and safety measures. Additionally, by excluding visibility equipment for specific body parts like the head, hands, and feet, as well as equipment integrating active lighting, the standard maintains focus on the overall effectiveness of general apparel in medium risk contexts. Overall, the EN 17353:2020+A1:2025 standard effectively addresses the need for enhanced visibility in protective clothing. Its well-defined requirements and scope make it a critical resource for manufacturers and users alike, ensuring safety and compliance in medium risk environments while giving prominence to the essential aspects of visibility and signalling.
