TS ISO 633

TS ISO 633 is a terminology standard for cork used as an industrial raw material. It also systematises the terms used to describe the different forms in which cork may appear, together with the main products, certain operations, and anomalies associated with cork. As a vocabulary standard, it helps manufacturers, laboratories, buyers, and technical documentation use the same terms for the same concepts.

Naming the different forms of cork

The focus of this standard is that cork from the cork oak is not treated as a single uniform item but as a material that can appear in multiple forms and conditions. In general technical context, cork may be encountered as bark, sheets, granules, cuttings, or processed products. Clarifying the vocabulary helps distinguish raw material from finished or semi-finished forms, and separates a product’s physical form from its quality or intended use.

Main products, operations and anomalies

The standard also covers the terms and definitions relating to cork’s main products and to some of the operations to which cork may be submitted. In general terms, this supports consistent wording for concepts within the production chain such as cutting, shaping, preparation, sorting, or grading. It also addresses anomalies that may be associated with cork, which is important for consistent technical descriptions and quality reporting; however, the exact limits, test methods, or acceptance criteria of this document cannot be inferred from the title and abstract alone.

Terminology standards regulate how a subject is described rather than how the material itself is manufactured. TS ISO 633 therefore serves as a reference framework that improves clarity in cork industry communication and reduces ambiguity in commercial and technical usage.
