EN 13279-2 is a European Standard that specifies the reference test methods for gypsum binders and gypsum-based plasters used in building applications. It covers the determination of hardness, flexural strength, compressive strength, and adhesive strength.

These materials are commonly used for plastering walls and ceilings in interior construction, where they serve as a finishing layer. The standard applies to both manual and mechanical applications of gypsum products, including those modified with additives, admixtures, or aggregates.
