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 d
