This international standard for high-visibility clothing specifies the visibility of the user on the work floor. Everyone who works on streets, roads or building sites must wear clothing that meets the EN ISO 207471:2013 standard so the wearer is visually identifiable. The purpose of this clothing is to increase the visibility of the user both at night and during the day. Therefore, this clothing should not be covered by other outfits or have large logos printed on it that impair the reflective surface and hence the visibility. The clothing may be personalised, but this must be approved beforehand by a registered body. You can obtain advice from your safety adviser about this. The number next to the pictogram indicates the class to which the clothing belongs. This depends on the minimum surface area of the fluorescent and reflective material.
|Class||Background material m2||Reflective material m2|
The colour coordinates and the luminance factor must be within certain thresholds (before and after lighting). Requirements are also placed on the colour fastness of both the fluorescent colours and the contrasting colours. Furthermore, the clothing should have been tested by washing at least 5 times, unless specified otherwise on the clothing. The working life of the clothing not only depends on the number of times it has been washed, but also on usage, maintenance and correct storage. The clothing must be cared for correctly and it must be cleaned regularly. This is because the protective properties of the clothing are reduced when the clothing is dirty. The accompanying instructions describe how to care for the clothing. You can find the maximum number of times that the clothing can be washed next to the high-visibility symbol. However, this only refers to the highvisibility property of the clothing.
Class 1: this clothing should not be used for working on public highways. A higher class must be used here, even for brief visits. This class can be used in other situations by visitors who are accompanied by people wearing a higher class of clothing.
Class 2: this clothing can be worn during the day, provided that the good weather conditions and visibility are good. It is recommended for all types of work, irrespective of the duration of the work.
Class 3: this clothing can be worn in the same circumstances as class 2. However, it is compulsory where visibility is limited, when work is carried out at night and in poor weather conditions.
