Clear and reliable standards are essential for the effective and safe use of fibre-reinforced concrete. From fibre classification and mechanical property testing to structural design principles, this MC-Pedia article offers a structured overview of the key norms and guidelines – in Germany and internationally.

The design and application of fibre-reinforced concrete require both a standards-compliant classification of the fibres used and the testing of relevant mechanical properties. Structural design is typically based on the internationally recognised fib Model Code 2010. In Germany, additional national guidelines such as the DAfStb Code of Practice for Steel Fibre Concrete apply. These not only supplement the Model Code but also ensure compliance with building authority requirements. The following overview summarises the most important standards and their fields of application.

Fibre classification

Standard	Title / Content	Application
EN 14889-1	Fibres for concrete – Part 1: Steel fibres – Definitions, specifications, conformity	Classification of steel fibres for load-bearing and non-load-bearing use
EN 14889-2	Fibres for concrete – Part 2: Polymer fibres – Definitions, specifications, conformity	Classification of polymer fibres, with distinction between Class I and II

Testing mechanical properties of fibre-reinforced concrete

Standard	Title / Content	Application
EN 14651	Testing of fibre-reinforcedconcrete – Determination of flexural tensile strength using notched specimen	Measures residual flexural tensile strength for verification of structural performance
EN 14488-5	Test methods for sprayed concrete – Part 5: Energy absorption capacity under bending load	Characterises post-crack energy absorption
