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.
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:
— Table 2 as required by Type B1 and Type B2; or
— Table 3 as required by garment Type A, Type B3 and Type AB.

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 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.
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.
NOTE Examples of Type B3 garments are reported in Annex E.
Visibility from all sides shall be reached as follows:
— not less than 40 % of the minimum required amount of retroreflective material specified in Table 3
is present on both the front and the back when laid flat, and
— not le

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.
Table 1 shows the different types.

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.
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.
NOTE Examples of Type B3 garments are reported in Annex E.
Visibility from all sides shall be reached as follows:
— not less than 40 % of the minimum required amount of retroreflective material specified in Table 3

SIST EN 17353:2020 표준 문서는 중간 위험 상황에서의 시각적 신호를 제공하는 보호 의류와 장치에 대한 요구 사항을 명확히 규정하고 있습니다. 이 표준의 주요 목적은 일조 조건이나 어두운 환경에서 차량의 헤드라이트나 탐조등에 의한 조명 아래에서도 착용자의 가시성을 보장하여, 사용자의 존재를 효과적으로 전달하는 것입니다. 이 표준의 강점은 색상 및 재귀반사성에 대한 성능 요구 사항, 보호 장비에 사용되는 재료의 최소 면적 및 배치에 관한 기준을 포함하고 있다는 점입니다. 이는 사용자가 중간 위험 상황에서도 충분히 두드러지게 보일 수 있도록 설계되어 안전성을 높이는 데 기여합니다. 또한, SIST EN 17353:2020 표준은 고위험 상황에서의 가시성 요구 사항(EN ISO 20471에 포함), 머리, 손 및 발을 위한 시각적 장비(예: 헬멧, 장갑, 신발)에 대한 요구 사항, 능동 조명을 통합한 장비(예: LED) 및 저위험 상황에 대한 가시성 장비에는 적용되지 않는다는 점을 명확히 함으로써, 특정 상황에 맞는 올바른 안전 장비 선택에 도움을 줍니다. 이러한 구체적인 범위 설정은 사용자가 필요한 보호 장비를 정확히 파악하고 선택할 수 있도록 안내하는 데 유용합니다. SIST EN 17353:2020 표준은 중간 위험 상황에서의 보호 장비에 대한 요구 사항을 체계적으로 정립하여 안전 작업 환경을 조성하는 데 큰 기여를 할 것으로 기대됩니다.
SIST EN 17353:2020は、中リスク状況における視認性の向上に特化した保護衣類および機器に関する重要な標準を提供します。このドキュメントは、ユーザーの存在を視覚的に信号することができるように設計された衣服や装置の要件を明確に示しています。この標準の適用範囲は、あらゆる昼間条件下および暗闇での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やすさを提供することにあります。 この標準の強みは、カラーや再帰反射のパフォーマンス要求に加え、保護装備内の材料の最小面積および配置に関する具体的な基準が含まれている点です。これにより、使用者が中リスク状況において効果的に視認されるための科学的根拠に基づいた要件が満たされています。 一方で、この標準は、高リスク状況における高可視性装置（EN ISO 20471に準拠）や、頭部、手、足専用の視認性機器（ヘルメット、手袋、靴など）、およびアクティブ照明を統合した機器（例えば、LED）には適用されないことが明確にされています。また、低リスク状況に対する視認性装置についても適用外であるため、使用対象が明確に絞られていることが特徴です。 この標準の関連性は、作業環境での安全性向上に寄与することにあり、特に中リスクの作業現場において、使用者が視認されやすくするための指針を提供することが評価されています。従って、SIST EN 17353:2020は、保護衣類および視認性機器の設計・製造に関わる専門家にとって、重要な基準として位置付けられています。
The EN 17353:2020 standard serves as a critical framework for the development and assessment of enhanced visibility equipment tailored for medium risk situations. Its scope clearly outlines the intended purpose of such equipment, focusing on garments and devices designed to effectively signal the wearer's presence, thereby ensuring conspicuity in varied environments. One of the strengths of this standard is its comprehensive inclusion of performance requirements related to both color and retroreflection. These specifications are essential for guaranteeing that enhanced visibility equipment maintains a high level of effectiveness under different lighting conditions, be it daylight or artificial lighting from vehicle headlights and searchlights. The standard also mandates minimum areas and specific placements of reflective materials, ensuring that the protective clothing provides optimal visibility, thereby enhancing safety. Additionally, EN 17353:2020 emphasizes applicability and limitations, which is a notable aspect of its design. By clearly stating what the document does not cover-such as high visibility equipment for high-risk situations, equipment for the head, hands, and feet, and devices with integrated active lighting-it prevents ambiguity and helps manufacturers focus on medium risk scenarios without conflating the requirements with those meant for other contexts. The relevance of EN 17353:2020 cannot be overstated, especially in environments where the risk level is moderated and the visual awareness of individuals is crucial. By adhering to this standard, manufacturers can ensure that their enhanced visibility equipment not only meets practical safety needs but also complies with recognized benchmarks, effectively contributing to the broader objectives of occupational safety and health.
