TS EN 923

TS EN 923 is a terminology and definitions standard for adhesives. Standards of this kind help manufacturers, users, laboratories, purchasers, and quality teams use the same technical language for the same concepts, supporting consistent communication about bonding, surface preparation, curing, and performance assessment. Because the official scope text is unavailable, this page introduces the subject through general technical context rather than unverified clause-level detail.

Why adhesive terminology matters

Adhesives are not a single class of material but a broad family of systems differentiated by chemistry, application method, curing behavior, and the substrates they are intended to join. A terms-and-definitions standard helps distinguish concepts such as adhesive, adhesion, cohesion, tack, open time, and cure. Those distinctions are important because the same product may be described differently depending on whether the focus is on initial grab, final bond strength, or the mechanism by which the joint develops strength.

General technical background on adhesive systems

Adhesive technology includes resin-based formulations, water-based products, solvent-based systems, hot melts, and reactive adhesives. These materials may form a bond by drying, cooling, chemical reaction, or a combination of processes. Some create flexible joints, while others produce rigid structural bonds. Clear terminology is especially useful when comparing product families, specifying application conditions, or discussing surface treatment and compatibility with different materials.

• Supports consistent use of technical vocabulary.
• Clarifies distinctions between adhesive families and bonding concepts.
• Helps align product data, test reports, and technical communication.
• Provides a common language for selection, quality control, and procurement.
