NBN EN 685:2007

This European Standard establishes a classification system for resilient, textile and laminate floor coverings. The classification is based on practical requirements for areas of use and intensity of use and is linked to the requirements specified in the European Standard for each type of floor covering.
This European Standard is also intended to give guidance to manufacturers, specifiers and consumers to enable them to choose the appropriate class of floor covering for any given area of use or specific room.
NOTE The wear and appearance of floor coverings are influenced by standards of installation and maintenance, the condition of the sub-floor and the kind of use (type of footwear, high concentrations of localized traffic etc.). These factors should be taken into account when using this classification system.
