TS EN 633

TS EN 633 is a terminology and classification standard for cement-bonded particleboards. Standards of this type establish a common technical language for the product family: they define what the material is called, how it is identified, and how it is grouped. Cement-bonded particleboard is a composite board made from wood particles bonded with a cement-based binder, which distinguishes it from ordinary particleboards made with organic resin systems.

What the terminology and classification are meant to organise

The focus of this standard is the conceptual boundary of cement-bonded particleboards. In general technical terms, cement-bonded boards belong to a broader group of mineral-bonded wood composites, where the cementitious matrix gives them a different profile of dimensional stability, surface behaviour, and often improved suitability for demanding service conditions compared with resin-bonded boards. Because this is a definition-and-classification document, it supports consistent naming, product grouping, and technical communication; it should not be read as a performance test standard unless separately stated.

Explicit scope limits

• Particleboards manufactured with organic binders are excluded.
• Particleboards manufactured with a gypsum binder are excluded.
• The document covers the definition and classification of cement-bonded particleboards.
• Its practical value is to separate this board type from other particleboard families by binder system.

For manufacturers, specifiers, and technical writers, TS EN 633 is mainly useful as a vocabulary reference and a product-family classifier. It helps ensure that cement-bonded particleboards are discussed with consistent terminology and not confused with particleboards based on different binders or different composite-board technologies.
