IS 15401 categorizes wall coverings in roll form primarily by material composition and surface features. It recognizes types such as paper-based, vinyl, and plastic coverings. Subtypes include plain, embossed, printed, foil-backed, fabric-backed, and specialized functional variants like washable or fire-retardant coverings. The standard focuses on defining terminology and symbols to describe these types without prescribing performance specifications.
The standard uses specific symbols to represent installation techniques. For example, Symbol 7.1 identifies the method involving overlap and double cutting, while Symbol 5.3 indicates a wall covering that is prepasted. These symbols aid in communicating application instructions clearly on product labels and installation guidelines.
IS 15401 classifies cleanability into levels such as Superior Cleanability, where dirt and most water-based stains can be removed with mild cleaning agents, and Basic Cleanability, which allows adhesive removal during hanging but no further washability. It also aligns with IS 15418 for washability standards. Textured coverings with materials like grass or cork are also noted as affecting cleanability.
Removal methods are represented with specific symbols: 'IV' denotes strippable coverings, 'Ik' indicates peelable types, and 'R' signifies wet removable varieties. These symbols clarify the recommended removal process and are used on product specifications to guide users.
Colour fastness to light is rated on a scale aligned with IS 15418, with ratings ranging typically from moderate (rating 3) to excellent (rating 7). Symbols associated with these levels, often sun or light bulb icons, are used to mark products, helping to communicate resistance to fading when exposed to light.
