Introduction
This European Standard provides a solution that enables the major issues to be resolved. The performance of
the conspicuous materials to be used in "high visibility clothing" is specified together with minimum areas and
placement of the materials.
Conspicuity is enhanced by high contrast between the clothing and the ambient background against which it is
seen; and by larger areas of the conspicuous materials specified.
Three areas of background and combined performance material colours are defined in an appropriate manner
for clothing material, all of which will confer conspicuity against most backgrounds found in urban and rural
situations in daylight. However users should consider the prevailing ambient background in which protection is
required and select the colour that provides the preferred contrast.
Two levels of separate performance retroreflective materials are included. Higher levels of retroreflection
provide greater contrast and visibility of warning clothing when seen in headlights during darkness. When
greater 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 of
retroreflective materials within the garment.
Three classes of warning clothing are specified in terms of the minimum areas of the materials to be
incorporated. Whilst the area comprising clothing is obviously dictated by the type of clothing and also the size
of the wearer, it should be noted that class 3 clothing offers greater conspicuity against most urban and rural
backgrounds 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 based
on a risk assessment of the condition in which the warning clothing is to be used. This will involve
consideration of the requirements necessary for an observer to understand that a wearer is present. The
observer needs both to perceive and to recognise the wearer and then to decide to take appropriate
avoidance action. The wearing of a high-visibility garment does not guarantee that the wearer will be visible
under all conditions.
Test methods ensure that a minimum level of protection is maintained when the garments are subjected to
care procedures. Test methods detailed in this standard are for new materials and not intended for products in
use.
Attention is drawn to EN 1150, which specifies characteristics and properties for visibility clothing for non-
professional use.

The EN 471:2003+A1:2007 standard is a comprehensive and well-structured guideline that focuses on high-visibility warning clothing designed for professional use. The scope of this European Standard is significant, as it addresses requirements essential for creating protective apparel that effectively signals the user's presence in various hazardous situations. This includes ensuring conspicuity under all light conditions during the day and under vehicle headlights in darkness, thus enhancing safety for those working in environments where visibility is critical. One of the primary strengths of this standard is its emphasis on performance requirements related to color and retroreflection. The clear specifications for the minimum areas of high-visibility materials and their strategic disposition within protective clothing ensure that users are not only easily seen but also protected from potential hazards. By establishing precise criteria for observable features, EN 471 provides manufacturers with a solid framework to produce garments that meet safety expectations. Furthermore, the relevance of EN 471:2003+A1:2007 cannot be overstated in today’s safety-conscious work environments. As industries face increasing scrutiny regarding worker safety measures, adherence to this standard can be a key differentiator for companies that prioritize the well-being of their employees. The standard directly correlates with legislative requirements and provides a benchmark that assists in meeting legal obligations concerning workplace safety. In summary, the EN 471:2003+A1:2007 standard presents a robust approach to defining high-visibility warning clothing for professional use. By incorporating rigorous test methods and requirements, it effectively enhances the visibility and safety of workers in potentially dangerous situations, fulfilling a critical need for protective clothing in various sectors.
Die Norm EN 471:2003+A1:2007 legt wesentliche Anforderungen für hochsichtbare Warnkleidung fest, die für den professionellen Gebrauch konzipiert ist. Der Anwendungsbereich dieser europäischen Norm umfasst die Schutzkleidung, die darauf abzielt, die Sichtbarkeit des Benutzers in gefährlichen Situationen zu gewährleisten, und zwar sowohl bei Tageslicht als auch bei Dunkelheit, wenn sie von Scheinwerfern von Fahrzeugen beleuchtet wird. Ein herausragender Aspekt dieser Norm ist die detaillierte Festlegung von Leistungsanforderungen hinsichtlich Farben und Retroreflexion. Diese Vorgaben stellen sicher, dass die Schutzkleidung nicht nur auffällig ist, sondern auch unter verschiedenen Lichtverhältnissen effektiv wirkt. Die Norm beschreibt zudem die Mindestflächen und die Anordnung der Materialien in der Schutzkleidung, wodurch ein hoher Sicherheitsstandard gewährleistet wird. Die Relevanz der EN 471:2003+A1:2007 liegt in ihrer Anwendung in zahlreichen beruflichen Bereichen, in denen die Sichtbarkeit eine entscheidende Rolle spielt, wie beispielsweise im Bauwesen, im Verkehrswesen und bei Notfalleinsätzen. Die Einhaltung dieser Norm fördert nicht nur die Sicherheit der Benutzer, sondern trägt auch zur Erhöhung des Bewusstseins für die Risiken in gefährlichen Arbeitsumgebungen bei. Damit bietet die Norm EN 471:2003+A1:2007 nicht nur einen klaren Rahmen für die Herstellung von hochsichtbarer Warnkleidung, sondern stellt auch sicher, dass diese Kleidungsstücke funktional und effektiv sind, um den Bedürfnissen der Nutzer gerecht zu werden. Die Standardisierung ist somit ein unverzichtbares Instrument zur Verbesserung der Sicherheit am Arbeitsplatz.
