tekstuuriluokka

Tekstuuriluokka is a classification system used primarily in the fields of material science, construction, and textile production to describe and compare the surface characteristics of finished products such as flooring, wallcoverings, paints, and fabrics. The system assigns each material a numerical or alphanumerical code that indicates its perceived roughness, pattern, and tactile quality.

In flooring and carpet production, tekstuuriluokka ranges are often defined by industry groups such as the European Committee for Standardization (CEN) and the Finnish standard organization (SAI). Materials are tested for their tactile response to hands or tools, their abrasion resistance, and their visual grain or weave pattern. Texturiluokat may be grouped into categories such as smooth, lightly textured, medium textured, and heavily textured, with additional subcategories for specific applications like high-traffic commercial areas or residential use.

The classification assists manufacturers, architects, and consumers in making informed decisions. For instance, a high tekstuuriluokka in a commercial space can reduce slip hazards, whereas a low tekstuuriluokka in a decorative wallcovering may be preferred for its sleek appearance. In textiles, the same principles apply; the texture class can indicate a fabric’s suitability for upholstery versus high-durability garments.

Internationally, tekstuuriluokka is aligned with related systems such as the American Society for Testing and Materials (ASTM) texture scales and the International Organization for Standardization (ISO) surface roughness conventions. While the specific parameters and decimal values may differ, the underlying goal remains the same: a standardized, objective description of material texture for use in design, specification, and safety compliance.
