Up-to-date lists and bibliographical references concerning such national standards may be obtained on application to the CEN Management Centre or to any CEN member. This European Standard exists in three official versions (English, French, German). A version in any other language made by translation under the responsibility of a CEN member into its own language and notified to the CEN Management Centre has the same status as the official versions. CEN members are the national standards bodies of Austria, Belgium, Bulgaria, 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.

5 EN :2007 (E) Foreword This document (EN :2007) has been prepared by Technical Committee CEN/TC 104 Concrete and related products, the secretariat of which is held by DIN. 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of an identical text or by endorsement, at the latest by January 2008, and conflicting national standards shall be withdrawn at the latest by May It has been drafted by Working Group 11 Fibres for concrete, the secretariat of which is held by BSI. This European Standard is one of a series dealing with test methods for assessing the performance of fibres, either steel or polymer, in concrete. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, 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
6 EN :2007 (E) 1 Scope This European Standard specifies the composition and characteristics of reference concretes used to evaluate the performance of fibres in concrete. The purpose of the reference concrete is to determine the general suitability of a fibre for use in concrete. NOTE The end user needs to satisfy themselves about the effectiveness of the fibre in their own concrete. 2 Normative references The following referenced documents are indispensable for the application of this document.

It has been developed from EN 1766 and should be read in conjunction with that standard. The reference concretes shall be designed to meet a prescribed flexural tensile strength, as defined in Table 1. The performance of a fibre shall be determined in a mandatory 16 mm or 20 mm maximum aggregate size mix using the test method described in EN for the effect on strength of concrete, and by one of the 4
