Bibliography

Specifies requirements for high visibility warning clothing. Includes performance requirements for colour and retroflection as well as for the minimum areas and for the disposition of the materials. Coverage includes care labelling, marking, instructions for use, and photometric and physical performance requirements for the retroreflective material and combined performance material. Also gives definitions, tables, diagrams and annexes.
