TS EN ISO 18451-1

TS EN ISO 18451-1 is a terminology standard that defines general terms used in the field of pigments, dyestuffs and extenders. Standards of this kind establish a shared technical language across related industries, supporting clearer communication, consistent product descriptions and better comparability of technical data.

The technical framework behind the terms

Pigments, dyestuffs and extenders are distinct material classes used to control colour, appearance and opacity. Pigments are typically insoluble particles that provide colour or functional effects; dyestuffs are colourants understood through their colouring role; and extenders are filler-like materials used to contribute bulk and, in some formulations, influence physical properties. Keeping these terms distinct matters in formulation work, specifications and technical documentation.

Why this part is useful in practice

• It provides a common vocabulary for terminology used in this technical field.
• It helps reduce ambiguity in laboratory, production and commercial documents.
• It supports clearer distinction between closely related terms such as pigment, dyestuff and extender.
• It improves consistency in technical communication and product descriptions.

In general, a terminology document like this is about clarifying concepts rather than prescribing how materials are made or tested. TS EN ISO 18451-1 therefore serves as a conceptual reference for engineers, formulators, quality personnel and technical writers working with colouring and extending materials.
