tst 7260

Tst 7260 is a terminology standard focused on the terms and definitions used to describe the color and other appearance characteristics of materials. In textiles and related material fields, concepts such as color, gloss, opacity, transparency, surface texture, and overall visual appearance are often discussed together and can easily be confused. This standard helps establish a common technical language for those appearance-related descriptions.

Why appearance characteristics are treated separately

Color is only one part of how a material is perceived. The same material may look different under different lighting, with a different surface finish, or because of its fiber structure or coating. For that reason, appearance terminology often extends beyond simple color names. In general technical context, attributes such as reflectance, dullness, gloss, translucency, and surface irregularity matter because they affect how a product is specified, compared, and communicated about across production and quality-control settings.

How to read this document in practice

• The subject of the document is the terms and definitions for color and other appearance characteristics of materials.
• It is a terminology document, not a source for test procedures or numerical compliance limits.
• It supports the use of shared terms in textile appearance evaluation.
• It helps distinguish color from other visual and surface-related attributes.

In that sense, Tst 7260 provides a useful reference framework for reducing ambiguity in textile and materials terminology. In general technical use, standards of this kind make product descriptions, catalogue language, and technical communication more precise and easier to compare.
