Warnkleidung - Prüfverfahren und Anforderungen
Diese Europäische 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 Mindestflächen und die Anordnung der Materialien in der Schutzkleidung.
Vetements de signalisation a haute visibilité pour usage professionnel - Méthodes d'essai et exigences
Le présent document norme spécifie les caractéristiques que doivent avoir les vetements ayant pour but de signaler visuellement la présence de l'utilisateur, afin de le détecter et de bien le voir dans des situations dangereuses, dans toutes les conditions de luminosité, de jour, et la nuit dans la lumiere des phares.
Les exigences de performance sont indiquées pour la couleur et la rétroréflexion ainsi que pour les surfaces minimales et le positionnement des matériaux utilisés.

EN 471:2003 (E)5IntroductionThis European Standard provides a solution that enables the major issues to be resolved. The performance ofthe conspicuous materials to be used in "high visibility clothing" is specified together with minimum areas andplacement of the materials.Conspicuity is enhanced by high contrast between the clothing and the ambient background against which it isseen; and by larger areas of the conspicuous materials specified.Three areas of background and combined performance material colours are defined in an appropriate mannerfor clothing material, all of which will confer conspicuity against most backgrounds found in urban and ruralsituations in daylight. However users should consider the prevailing ambient background in which protection isrequired and select the colour that provides the preferred contrast.Two levels of separate performance retroreflective materials are included. Higher levels of retroreflectionprovide greater contrast and visibility of warning clothing when seen in headlights during darkness. Whengreater conspicuity is required the higher level of retroreflecting material should be used.Design requirements illustrating the disposition of retroreflective materials are included within the standard.The ergonomics of the wearer should be considered when selecting the most appropriate configuration ofretroreflective materials within the garment.Three classes of warning clothing are specified in terms of the minimum areas of the materials to beincorporated. Whilst the area comprising clothing is obviously dictated by the type of clothing and also the sizeof the wearer, it should be noted that class 3 clothing offers greater conspicuity against most urban and ruralbackgrounds than class 2 garments which in turn are significantly superior to class 1 clothing.Selection and use of high-visibility warning clothing can vary among European countries. It should be basedon a risk assessment of the condition in which the warning clothing is to be used. This will involveconsideration of the requirements necessary for an observer to understand that a wearer is present. Theobserver needs both to perceive and to recognise the wearer and then to decide to take appropriateavoidance action. The wearing of a high-visibility garment does not guarantee that the wearer will be visibleunder all conditions.Test methods ensure that a minimum level of protection is maintained when the garments are subjected tocare procedures. Test methods detailed in this standard are for new materials and not intended for products inuse.Attention is drawn to EN 1150, which specifies characteristics and properties for visibility clothing for non-professional use.
