TS EN ISO 12543-1

TS EN ISO 12543-1 is the part of the laminated-glass series that sets out the terms used for laminated glass and laminated safety glass in buildings and explains how the component parts of these products are described. It provides the common technical language for the series, helping distinguish the glass sheets themselves, the interlayer, and the layered assembly as a whole.

The structure of laminated glass

From a general technical perspective, laminated glass consists of two or more glass plies bonded together with an interlayer. That layered construction is important because it affects how the product behaves after breakage and how the assembly is discussed in design and specification work. The term “laminated safety glass” refers to the safety-oriented end of this product family, while this document itself focuses on definitions and component descriptions rather than setting performance limits or test methods.

Why component terminology matters

In building glass applications, each element of the assembly has a distinct technical role: the glass plies, the interlayer, the bond between them, and the finished laminated unit are not interchangeable concepts. Clear terminology supports consistent product descriptions, drawings, specifications, and references to later test or product standards. This part of the series helps align that vocabulary so users can describe multi-layer glazing systems without ambiguity.

• Defines the terms used for laminated glass and laminated safety glass in buildings.
• Describes the component parts of these products and how they are identified.
• Supports the shared vocabulary used across the rest of the series.
• Helps clarify the terminology of layered glazing systems in building applications.
