Overview
ISO 633:2019, "Cork - Vocabulary", provides an authoritative, international glossary for cork as an industrial raw material. The standard defines the terms used to describe the different forms of cork, the main cork products and by‑products, common preparation and shaping operations, and anomalies that can occur. Prepared by ISO/TC 87 (Cork), this third edition updates and clarifies terminology widely used by producers, manufacturers, inspectors and technical writers.
Why it matters: consistent terminology improves communication across the cork value chain, supports quality control, regulatory compliance and clear technical documentation for manufacturing and trade.
Key Topics
- Definitions of cork and its constitution - terms for the cork layer and annual veins as raw material.
- Forms and types - terminology for cork resulting from stripping and subsequent preparation.
- Products and by‑products - naming conventions for shaped products, granulated materials and agglomerates.
- Operations - standard terms for common manufacturing steps applied to cork (preparation, shaping, granulation, agglomeration).
- Cork stoppers and discs - specific terms for stopper parts, characteristics, types (by constitution and shape), and manufacturing practices.
- Anomalies - agreed vocabulary for visual and material defects that may affect performance or appearance.
Included features: the document contains a structured table of contents covering constitution, products, operations, stopper terminology, granulation/agglomeration products and related by‑products.
Applications
ISO 633:2019 is designed for practical use by:
- Manufacturers and converters of cork products who need a common terminology for production and specifications.
- Quality assurance and inspection teams documenting defects, acceptance criteria and corrective actions.
- Product development and R&D teams defining material inputs, product families and processing steps.
- Technical writers, procurement and legal teams preparing contracts, standards references and documentation for international trade.
Benefits include improved clarity in product specifications, reduced misunderstandings between suppliers and customers, and easier integration with other standards and testing protocols.
Related Standards
- ISO/TC 87 (Cork) - technical committee responsible for cork standardization.
- ISO/IEC Directives, Part 1 and Part 2 - editorial and development rules referenced in the foreword.
- ISO Online Browsing Platform and IEC Electropedia - for terminological resources used alongside ISO 633.
Using ISO 633:2019 as the authoritative vocabulary helps organizations harmonize terminology across manufacturing, quality control and documentation workflows for cork products, including stoppers, agglomerates and other cork‑based materials.
