TS 6308

TS 6308 is a terminology standard for cork stoppers made from Quercus suber L., covering their types and general definitions. Standards of this kind do not define product performance in the way a product specification does; instead, they establish the common technical language used to identify and classify the product family. In practical use, cork stoppers are valued for sealing containers, helping protect the contents, and providing a closure that can be removed and, in some cases, resealed; this document focuses on naming and definition.

The technical background of cork oak and stopper types

Cork oak bark is a natural material known for being light, elastic, and compressible, which makes it suitable for stopper manufacture. Different stopper types may be distinguished by size, appearance, manufacturing route, and intended use. From a general technical perspective, that distinction matters because the way a natural cork stopper recovers after compression affects how it fits and seals the bottle neck. A terminology standard helps keep these distinctions clear across manufacturing, purchasing, and technical communication.

What this standard contributes

• It provides a framework for types and general definitions for cork stoppers made from Quercus suber L.
• It supports consistent use of terminology between manufacturers, suppliers, and users.
• It helps keep naming aligned when referring to natural cork stopper categories.
• It is focused on terminology and definitions, not on prescribing production methods or product tests.
