One of the most important concepts introduced in SRPS EN 13670 is the Classification of Execution Classes. The standard recognizes that not all structures require the same level of rigor.
The execution requirements are divided into three classes based on the consequence of failure and the complexity of the structure:
The choice of class is usually specified by the designer in the project specification.
| Clause | Topic | |--------|-------| | 4 | Execution classes (EC1 to EC4) | | 5 | Formwork | | 6 | Reinforcement | | 7 | Concreting | | 8 | Curing | | 9 | Tolerances | | 10 | Inspection & testing | srps en 13670
Since Serbia is an EU candidate country, the adoption of EN standards (as SRPS) is actively encouraged. The Serbian Construction Law (Zakon o planiranju i izgradnji) requires that all constructions meet technical requirements. The most direct way to prove compliance is to follow harmonized technical standards.
SRPS EN 13670 sets strict limits on geometrical deviations. Even if concrete is strong, if it is built in the wrong place, it fails the standard.
It defines two tolerance classes:
Common tolerances include deviations in cross-section dimensions (e.g., a wall thickness) and vertical alignment (plumbness).
Formwork is more than just a mold. SRPS EN 13670 sets strict rules regarding:
Practical tip: In Serbian winters, using SRPS EN 13670's requirements for curing at low temperatures is mandatory to avoid delayed stripping and surface damage. One of the most important concepts introduced in
In the construction industry, concrete is the most widely used man-made material on the planet. However, the durability and safety of a concrete structure depend not only on the quality of the materials but critically on the execution of the work. This is where the standard SRPS EN 13670 comes into play.
For construction professionals in Serbia—from site engineers and contractors to project managers and quality control inspectors—compliance with SRPS EN 13670 is not optional. It is the national benchmark for how concrete structures should be built, inspected, and documented.
