The federal government of the United States stipulates that Wallpapers must have certain weight and performance standards. This regulation was implemented until 1997. After 1997, the weight regulation was canceled, and performance became the only factor to judge the type of wallpaper. The classification of wallpapers is determined according to the standards formulated by the federal government and the American Society for testing and materials (ASTM). The federal administration stipulates the requirements for its characteristics and performance in ccc-w-408d

The classification of wallpapers is determined according to the standards formulated by the federal government and the American Society for testing and materials (ASTM). The federal administration specifies the requirements for its characteristics and performance in ccc-w-408d. (ccc-w-408d also includes the data of flame retardancy in Steiner pipe test.) All these tests are carried out by qualified institutions. The types and uses of wallpaper stipulated by the federal government are as follows:

class I - used for ceilings and surfaces in areas that are not subject to wear. Class II - used in general pedestrian flow and vulnerable areas. Class III - mainly used as the material to protect the wall or the protective surface at the lower part of the wall, used in crowded places, such as the entrance of the hospital, where people often go in and out - areas that need handling equipment or are vulnerable to serious wear and tear
