High visibility clothing - Test methods and requirements (ISO 20471:2013)

This International Standard specifies requirements for high-visibility clothing which is capable of signalling the user's presence visually, intended to provide conspicuity of the user in high-risk situations under any light conditions by day and under illumination by vehicle headlights in the dark. For further information concerning risk situations see Annex A. This standard does not apply to medium-risk and low-risk situations Performance requirements are included for colour and retroreflection as well as for the minimum areas and for the placement of the materials in protective clothing.

Warnkleidung - Prüfverfahren und Anforderungen (ISO 20471:2013)

Diese Internationale Norm legt die Anforderungen an Schutzkleidung fest, die die Anwesenheit des Trägers visuell signalisiert, mit der Absicht, ihn in gefährlichen Situationen bei allen möglichen Lichtverhältnissen am Tage sowie beim Anstrahlen mit Fahrzeugscheinwerfern in der Dunkelheit auffällig zu machen.
Es sind Leistungsanforderungen an die Farbe und die Retroreflexion festgelegt, wie auch an die Mindest-flächen und die Anordnung der Materialien in der Schutzkleidung.
Diese Norm gilt nicht für Warnkleidung aus dem Sport- und Freizeitbereich. Für diese existieren andere Normen (siehe EN 1150:1999 und EN 13356:2001).
Diese Norm gilt nicht für die klassische Arbeiterbekleidung, für die der Hersteller den Anspruch erhebt, dass sie keine Schutzkleidung ist und sie nicht in Übereinstimmung mit den wesentlichen Anforderungen ist, selbst wenn einige kleine auffälligkeitserhöhenden Materialien für einen anderen Zweck verwendet werden.

Vêtements à haute visibilité - Méthodes d'essai et exigences (ISO 20471:2013)

L'ISO 20471:2013 spécifie les exigences que doivent respecter les vêtements à haute visibilité afin de signaler visuellement la présence de l'utilisateur. Les vêtements à haute visibilité sont destinés à offrir une perceptibilité du porteur lorsqu'il est vu par les conducteurs de véhicules ou d'autres équipements mécaniques, dans toutes les conditions de luminosité, de jour et de nuit dans la lumière des phares d'un véhicule.
Les exigences de performance sont indiquées pour la couleur et la rétroréflexion ainsi que pour les surfaces minimales et le positionnement des matières utilisées sur le vêtement de protection.

Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards

bodies (ISO member bodies). The work of preparing International Standards is normally carried out

through ISO technical committees. Each member body interested in a subject for which a technical

committee has been established has the right to be represented on that committee. International

organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of

electrotechnical standardization.

International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.

The main task of technical committees is to prepare International Standards. Draft International

Standards adopted by the technical committees are circulated to the member bodies for voting.

Publication as an International Standard requires approval by at least 75 % of the member bodies

casting a vote.

Attention is drawn to the possibility that some of the elements of this document may be the subject of

patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

ISO 20471 was prepared by Technical Committee ISO/TC 94, Personal safety — Protective clothing and

equipment, Subcommittee SC 13, Protective clothing.
This corrected version of ISO 20471:2013 incorporates the following correction:

— in the fourth paragraph of subclause 4.1 the requirement concerning the sleeves of a class 3 garment

Introduction

The performance of the conspicuity-enhancing materials to be used for high risk-related visibility clothing

is specified photometrically together with minimum areas and placement (design) requirements.

Conspicuity is the property that makes an object readily attract visual attention. This is a particularly

important feature in complex environments which have visually competing objects. Conspicuity

is determined by an object’s luminance contrast, colour contrast, pattern and design, and motion

characteristics relative to the ambient background against which it is seen.

Three classes of garment are defined based on three different minimum areas of retroreflective,

fluorescent and/or combined performance materials. Each of these classes will provide a different

level of conspicuity, class 3 being the class that provides the highest degree of conspicuity against most

backgrounds found in urban and rural situations in daylight and in night time. Users should select

the required class of performance based on a risk assessment of the location/situation in which the

protection afforded by clothing to this International Standard is required.

This International Standard contains requirements relating to risk assessment and risk analysis of

high visibility garments. Possible designs illustrating the placement of retroreflective materials are

included within the standard. Ergonomic factors such as fit/sizing, comfort, and range of motion of the

wearer should be considered when selecting the most appropriate configuration of retroreflective and

fluorescent materials within the garment.

Selection and use of high visibility clothing can vary among user countries and may be subject to local

regulations. This International Standard contains requirements relating to risk assessment of the

condition in which the high visibility clothing is to be used. This will involve consideration of the factors

which may affect an observer’s ability to detect that a person is present. The observer needs both to

perceive and to recognize the wearer and then needs to be able to take appropriate avoidance action.

The wearing of a conspicuity-enhancing high visibility garment does not guarantee that the wearer will

be visible under all conditions.

The minimum requirements given within this International Standard are determined by the specific

test methods and their assigned measuring values. The tests are partly performed on new materials

and partly on preconditioned materials. By preconditioning (e.g. folding of retroreflective material) a

load of the materials is simulated. However, it should be noted that laboratory testing may not represent

real life conditions. The conspicuity performance of a garment will depend on usage (e.g. dirt, solar

irradiation), care (e.g. cleaning agent, repair), storage (e.g. dust-free, lightproof), etc.

4.1 Types and classes

High visibility clothing is grouped into three classes related to risk assessment. Each class shall have

minimum areas of high visibility materials incorporated in the garment in accordance with Table 1. Garments

shall comprise the required areas of background material and retroreflective material or alternatively

shall comprise the required area of combined performance material. The area shall be measured on the

smallest garment size available with all fasteners adjusted to the smallest configuration possible.

The garment shall be made up of high visibility material on all sides. To ensure visibility from all sides

(360° visibility), it is important that horizontal retroreflective bands and fluorescent materials encircle

torso, trouser legs and sleeves.

The performance class can be obtained using a single garment or a clothing ensemble, e.g. jacket and

trousers. An assembly, e.g. a classified trouser and a classified jacket, can be classified as a higher class

if the assembly meets the minimum requirement achieved by the actually visible area when wearing

the garment. This higher class shall be additionally specified in both the information for use and on the

labels of both garments (see Clause 8).

Regardless of the area of materials used, a class 3 garment shall cover the torso and shall have as a

minimum either sleeves with retroreflective bands or full length trouser legs with retroreflective

bands, if not both.

SIST EN ISO 20471:2013
ISO 20471:2013(E)

At least (50 ± 10) % of the minimum area of visible background material shall be on the front part of

the garment. Only those areas of retroreflective materials that comply with the design requirements of

4.2 shall be used in the assessment of the minimum required area of retroreflective areas. When using

two or more background materials, the total area usable regardless of colour shall be measured. The

garment is to be measured flat on the table including torso, arms and legs.
NOTE For additional information on high visibility garment design, see Annex D.
4.2 Specific design requirements
4.2.1 Garments covering only the torso

The background material shall encircle the torso and shall maintain a minimum width (height) of 50 mm.

Interruptions of background material by retroreflective stripes are not counted. Bands of retroreflective

material shall be at least 50 mm wide.

Garments only covering the torso shall have one or more bands of retroreflective material encircling

the torso with a maximum inclination of ± 20° to the horizontal and bands of retroreflective material

joining the torso band from the front to the back over each shoulder. The bottom of the lowest torso

band shall be at least 50 mm above the bottom edge. If more than one horizontal band is applied the

horizontal bands shall be at least 50 mm apart.

Alternatively, garments covering only the torso shall have two bands of retroreflective material at least

50 mm apart and encircling the torso with a maximum inclination of ± 20° to the horizontal. The bottom

of the lowest torso band shall be at least 50 mm above the bottom edge.

Tabards shall be constructed so that a person of the size for which they are designed can wear the

tabard so that any gaps at the sides shall not be greater than 50 mm horizontally.

Any gap (for fastening systems and seams) in the lengthwise continuity of each band of retroreflective or

combined performance material shall not be greater than 50 mm, measured parallel to the direction of

the band, and the total of such gaps shall not be greater than 100 mm in any one band around the torso.

Examples of garments covering only the torso are given in Figure 1.
