TS EN 16572

TS EN 16572 is a terminology standard for mortars used in the conservation of cultural heritage, bringing together the technical terms and definitions used around masonry mortars, renders and plasters. Standards of this kind do not prescribe a performance test or material formulation; instead, they establish a shared language so that conservation teams, specifiers, researchers and suppliers can describe the same material and intervention consistently across documents and languages.

Where the terms are used

In general technical practice, masonry mortars are the jointing or bedding materials used with stone, brick or other units, while renders and plasters are coating layers applied to surfaces for protection, levelling or finishing. In cultural heritage work, those distinctions matter because compatibility with historic substrates, reversibility of interventions and accurate documentation depend on using the right term for the right material and function. A glossary standard supports that precision by defining the vocabulary rather than the repair method.

Language coverage and practical value

The standard gives the terms and definitions in the official CEN languages, and also provides equivalents in Dutch, Italian, Greek, Swedish and Spanish for information only. In broader professional use, multilingual terminology helps reduce ambiguity in conservation reports, tender documents, training materials and cross-border projects, especially where historic fabric, lime-based materials and surface finishes are discussed. The result is clearer communication around what kind of mortar or coating is meant, without implying a specific recipe or test requirement.

• Defines terminology for mortars used in cultural heritage conservation.
• Centers on masonry mortars, renders and plasters as technical categories.
• Uses the official CEN language versions as the authoritative terms and definitions.
• Includes additional language equivalents for information only.
