TSE CEN/TR 15225

TSE CEN/TR 15225 provides technical guidance on how factory production control can be organised for CE marking of designed masonry mortars under conformity attestation system 2+. The document focuses on producing the mortar consistently at the factory and on maintaining the declared performance values through controlled manufacturing practice.

Why factory production control matters

Factory production control is the structured control of manufacturing, from raw material acceptance through batching, mixing, record keeping and dispatch. For designed masonry mortars, this is especially important because the product’s properties are declared by the manufacturer; if process variables are not controlled, performance characteristics such as strength, workability and consistency may vary. This technical report gives general guidance for establishing that control framework.

Scope boundaries and related mortar categories

• The document is centred on designed masonry mortars and guidance for conformity attestation system 2+.
• For designed masonry mortars, the conformity system involves Notified Body participation within the framework described by this guidance.
• For prescribed masonry mortar, plaster and rendering mortar, conformity system 4 applies; in that case, Notified Body involvement is not required.
• Manufacturers of prescribed mortars may use this guidance as a basis for suitable factory production control procedures.
• The document supports production control in the context of CE marking guidance; it should not be read as a complete product standard defining every performance claim on its own.
