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.



EN 471:2003 (E)61 ScopeThis European Standard specifies requirements for protective clothing capable of signalling the user'spresence visually, intended to provide conspicuity of the user in hazardous situations under any lightconditions by day and under illumination by vehicle headlights in the dark.Performance requirements are included for colour and retroreflection as well as for the minimum areas and forthe disposition of the materials in protective clothing.2 Normative referencesThis European Standard incorporates by dated or undated reference, provisions from other publications.These normative references are cited at the appropriate places in the text, and the publications are listedhereafter.

EN 471:2003 (E)84 Design4.1 Types and classesThe warning clothing is grouped into three classes. Each class shall have minimum areas of visible materialsincorporated in the garment in accordance with Table 1. Garments shall comprise the required areas ofbackground material and retroreflective material or alternatively shall comprise the required area of combinedperformance material.
