TS EN 520+A1

TS EN 520+A1 is the standard that sets out the definitions, characteristics, performance requirements and test methods for gypsum plasterboards used in building works and, in some cases, as an intermediate product for further manufacturing. It also covers boards intended to form decorative surfaces or to receive gypsum plaster. In practical terms, it places gypsum plasterboard within the technical framework of drylining and interior finishing, rather than treating it as a generic panel material.

Where gypsum plasterboard fits in construction

Gypsum plasterboard is typically a factory-made board with a gypsum core and facings, used in partitions, linings, ceilings and other internal building applications. The standard’s scope links the product’s intended use to its technical characterization: boards for direct decoration, boards for subsequent processing, and boards prepared for gypsum plaster all belong to the same product family, but their expected performance and handling may differ in practice.

Why requirements and test methods matter

For gypsum boards, performance is usually discussed in relation to properties such as reaction to fire, mechanical resistance, dimensional stability and surface quality. General technical understanding matters because the board’s behavior depends not only on the gypsum core but also on facing papers, thickness, edge profile and the intended service environment. Test methods provide a consistent way to verify these characteristics so that product declarations can be compared on a common basis.

• The standard covers definitions and the basic classification logic for gypsum plasterboards.
• It applies to boards used in building construction works and boards intended for further manufacturing operations.
• It includes boards intended for direct decorative finishes or for receiving gypsum plaster.
• It brings requirements and test methods together to support consistent performance assessment.
