Fibres for concrete - Part 2: Polymer fibres - Definitions, specifications and conformity
This Part 2 of EN 14889 specifies requirements for polymer fibres for structural or non-structural use in concrete, mortar and grout.
NOTE Structural use of fibres is where the addition of fibres is designed to contribute to the load bearing capacity of a concrete element. This standard covers fibres intended for use in all types of concrete and mortar, including sprayed concrete, flooring, precast, in-situ and repair concretes.
Fasern für Beton - Teil 2: Polymerfasern - Begriffe, Festlegungen und Konformität
Diese Europäische Norm legt Anforderungen für Polymerfasern für Mörtel und Beton fest. Sie gilt für Fasern für tragende und nichttragende Zwecke einschließlich der Verwendung in Spritzbeton, Betonböden, Fertigbetonteilen, Tunnelauskleidungen und Instandsetzungsarbeiten.
Fibres pour béton - Partie 2 : Fibres polymère - Définition, spécifications et conformité
La présente Partie 2 de l’EN 14889 spécifie les prescriptions relatives aux fibres de polymère pour une utilisation structurelle ou non structurelle dans le béton, le mortier ou le coulis.
NOTE L’utilisation des fibres est structurelle si l’ajout de fibres est conçu pour contribuer à la capacité portante d’un élément en béton. La présente norme traite des fibres destinées à être utilisées dans tous les types de béton et de mortier, y compris le béton projeté, le béton pour dallage, le béton pour préfabrication, le béton coulé en place et le béton de réparation.

Part 2 dealing with polymer fibres
This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by February 2007, and conflicting national standards shall be withdrawn at the latest by May 2008. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of the Construction Products Directive. For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this document. This European Standard should be given the status of a national standard. No existing European Standard is superseded. Not all fibre characteristics that may be relevant to the performance of a fibre concrete, structural or non-structural, such as early age effects, creep and chemical attack, have been addressed in this standard due to the difficulties of formulating meaningful and reproducible standardised test methods. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.

3.5 aspect ratio ratio of length to equivalent diameter of the fibre 3.6 fibre shape specific outer configuration of the fibre, both in the longitudinal direction and in the shape of the cross section and also the possible surface coatings and or bundling of the fibres 3.7 tensile strength of the fibre stress corresponding to the maximum force a fibre can resist. The tensile strength is calculated by dividing the maximum force a fibre can resist by the mean cross sectional area of the fibre.
3.8 elongation of the fibre
elongation of the fibre is defined as the ratio of the length change of the fibre to the initial length expressed as a percentage NOTE The length change should be measured on the fibre itself. 3.9 elastic modulus of the fibre
initial slope of the tensile stress versus elongation curve 3.10 linear density mass per unit length of a yarn or filament expressed in tex or its multiples or submultiples NOTE 1 tex = 1g/1000m 3.11 tenacity breaking force of a fibre divided by its linear density 3.12 melting point temperature at which a polymer becomes liquid 3.13 point of ignition temperature at which combustion is initiated 3.14 residual flexural strength notional stress at the tip of the notch which is assumed to act in an uncracked mid-span section, with linear stress distribution, of a prism subjected to the centre-point load Fj corresponding to CMODj where CMODj > CMODFL; or to δj where δj > δFL (j = 1,2,3,4). 3.15 crack mouth opening displacement (CMOD) linear displacement measured by a transducer installed on a prism
