Overview
EN 14889-2:2006 - published by CEN - is the European standard for polymer fibres for concrete. It sets definitions, specifications and conformity requirements for polymer fibres intended for structural or non‑structural use in concrete, mortar and grout. The scope explicitly includes all delivery forms such as sprayed concrete, flooring, precast, in‑situ and repair concretes. The standard supports regulatory compliance (see informative Annex ZA) with the EU Construction Products Directive.
Key topics
- Classification: Fibres are categorised by physical form:
- Class I (micro fibres) - diameter < 0.30 mm (subclasses Ia mono‑filamented, Ib fibrillated)
- Class II (macro fibres) - diameter > 0.30 mm (used where residual flexural strength is required)
- Declared properties and tolerances:
- Length, (equivalent) diameter, aspect ratio and linear density must be declared.
- Tolerance examples from the standard: length >30 mm ±10% (individual), average ±5%; length ≤30 mm ±1.5 mm; Class II diameter and aspect ratio tolerances up to ±50%; Class I linear density ±10%.
- Material and geometry:
- Polymer type (polyolefins, polyesters, nylon, PVA, etc.) and fibre shape (straight, deformed, bundled) must be declared.
- Surface treatments/coatings (spin‑finish, adhesives) must be declared and controlled because they affect dispersion and air entrainment.
- Mechanical and thermal properties:
- Tensile properties (tenacity for Class I, tensile strength for Class II), modulus of elasticity, melting point and point of ignition are specified for conformity assessment.
- Performance effects and testing:
- Requirements cover effects on workability/consistence, strength of concrete, mixing behaviour and potential release of dangerous substances.
- Conformity assessment includes initial type testing and ongoing Factory Production Control (FPC), traceability and corrective action procedures.
Applications
- Use this standard when specifying, manufacturing or testing polymer fibres for concrete applications such as:
- Crack control in floors and slabs (micro fibres)
- Load-bearing enhancement and residual flexural capacity in structural members (macro fibres)
- Sprayed concrete, repair mortars, precast elements and industrial flooring
- It is essential for product declaration, CE marking and technical dossiers for construction products in EU markets.
Who should use this standard
- Fibre manufacturers and formulators
- Concrete and mortar producers
- Structural and materials engineers specifying fibre‑reinforced concrete
- Test laboratories and certification bodies
- Contractors and precast fabricators evaluating fibre performance

5 Requirements 5.1 Classification of fibres Polymer fibres shall be characterised by the manufacturer in accordance with their physical form: Class Ia:
Micro fibres:
< 0,30 mm in diameter;
Mono-filamented Class Ib
Micro fibres:
< 0,30 mm in diameter; Fibrillated Class II:
Macro fibres:
> 0,30 mm in diameter NOTE Class II fibres are generally used where an increase in residual flexural strength is required.
5.2.3 Bundled polymer fibres The type and size of the fibre bundle (e.g. glued, wrapped) shall be declared. 5.2.4 Surface treatment or coating Any surface treatment or coating (type and quantity), and any chemical or physical treatment of polymer fibres shall be declared and controlled. NOTE Spin finish is a term used to describe the addition of chemical(s) used to coat the fibres that will then help the fibre to disperse in concrete.
Without this coating some fibres will not easily disperse in concrete and will tend to ball up.
However some types of chemical used to coat the fibres can induce air into the concrete or mortar.
It is therefore important that any coating added to the fibre is controlled and is recorded as part of the initial type testing and as part of the factory control procedures. 5.3 Dimensions and tolerances 5.3.1 General The length, diameter and aspect ratio shall be declared for all fibres. The linear density shall be declared for Class I fibres.
Specimens of fibres, when sampled in accordance with 6.2.2 and measured in accordance with 5.3.2 and 5.3.3 shall not deviate from the declared value by more than the tolerances given in Table 1.
