Steel bars must be cut and bent at controlled temperatures using approved machinery. Heating the steel to make bending easier is generally prohibited unless strictly authorized, as it alters the mechanical properties of the metal.
The standard is organized into practical areas that serve as a checklist for ensuring structural safety and serviceability:
The standard introduces three Execution Classes (EC1, EC2, and EC3) to match the level of supervision and inspection to the complexity and risk of the project: srps en 13670
While the prestandard provided a foundation, it was a transitional document. The full standard that replaced it incorporates the knowledge gained and solidifies the requirements, making it the only valid reference for projects subject to the current regulations.
Marko stood on the edge of the sprawling Belgrade construction site, the wind whipping dust across the fresh excavations. As the lead engineer for the "Sava Heights" project, the weight of the sixteen-story residential tower rested on his shoulders. In his hand, he held a worn copy of . Steel bars must be cut and bent at
SRPS EN 13670 is a vital standard within the Serbian construction ecosystem. By defining clear processes for formwork, steel placement, concreting, curing, and inspection, it ensures that theoretical engineering calculations translate successfully into safe, durable, and resilient concrete structures. Compliance with this standard is essential for any modern construction project operating under Serbian and European technical regulations.
However, the standard explicitly states what it does not cover. It does not apply to concrete members used solely as equipment or construction aids, does not cover the specification and production of the concrete itself, and excludes safety and health aspects, as well as contractual or third-party safety issues. The full standard that replaced it incorporates the
To ensure a project is compliant, SRPS EN 13670 requires two documents:
From transport and delivery to pouring and compaction, the standard provides actionable guidelines to avoid segregation. It highlights proper vibration techniques to ensure the elimination of air voids without compromising the uniformity of the mix. Curing and Protection
Defines the allowable deviations in the final dimensions of the structure to ensure it matches the original design intent. Implementation in Serbia SRPS EN 13670:2012
