TS EN 13279-1

TS EN 13279-1 is the first part of the standard for gypsum binders and gypsum plasters, focusing on gypsum-based powder products used in building applications. It establishes the technical framework for how these materials are defined, characterised and assessed in terms of performance, creating a common basis for comparing product types.

The technical framework for gypsum binders and plaster products

Gypsum-based binders are mineral materials that set and harden when mixed with water. In plaster products, they are used for surface levelling, coating, filling and finishing layers. In general technical terms, this standard organises how such powder products are identified and what performance aspects they belong to; the brief scope alone does not allow any claim about detailed test procedures or numerical limits.

Characteristics that matter in building use

For gypsum-based building products, the key technical considerations typically include workability, behaviour during mixing with water, hardened strength and surface properties suited to the intended application. In indoor building work, gypsum products are valued for helping create smooth surfaces and suitable substrates for subsequent finishes. The scope of this standard is limited to defining the characteristics and performance of powder products for building purposes; it is not a substitute for project-specific design or application instructions.

In broader construction practice, gypsum materials may also be considered in relation to fire behaviour, thermal performance and acoustic use. Here, however, the essential value of TS EN 13279-1 is to provide a clear product-level reference so gypsum-based building products can be discussed and evaluated using the same technical terminology across manufacturing, quality control and product comparison contexts.
