TS EN 1504-1

TS EN 1504-1 is a terminology standard for the products and systems used in the protection and repair of concrete structures. This part sets out the definitions of the terms used for repair systems and products intended for maintenance, protection, renewal and strengthening, helping the same technical concepts be understood consistently in design, specification, execution and conformity-related communication.

The role of a terminology standard

In concrete repair and protection work, terms such as “product”, “system”, “repair” and “strengthening” may sound close in everyday language but carry distinct technical meanings. This standard is concerned with defining those core concepts rather than prescribing the chemistry of products or detailed performance limits. That makes it valuable wherever specifications, tender documents, site instructions and quality discussions need a common vocabulary.

General technical context for concrete repair and protection

Concrete structures may require different forms of intervention, from surface protection and crack treatment to reinstatement of damaged concrete and measures that improve structural behaviour. In general technical practice, the selected system depends on the condition of the structure and the objective of the work. TS EN 1504-1 provides the definitional framework that supports clear use of the terms applied to those products and systems.

• It addresses the common terminology used for maintenance, protection, renewal and strengthening applications.
• It helps distinguish between a repair system and an individual product in technical communication.
• It supports consistent language in concrete-structure documentation and quality-related processes.
• This part is a definitions document; it is not a test method standard or a source of numerical acceptance limits.
