The increasing use of retroreflectors for pedestrians in the Nordic countries has led to a need for technical requirements in order to keep the quality of manufactured retroreflectors on a level that is concordant with present-day traffic safety demands. A project group has studied the properties of retroreflectors, including their retroreflection characteristics and their degradation with use which results in finite life time. The findings of the group has resulted in a proposal for a common Nordic set of test specifications for pedestrian retroreflectors.
