EN 15037-3:2009 (E) 4 Foreword This document (EN 15037-3:2009) has been prepared by Technical Committee CEN/TC 229 “Precast concrete products”, the secretariat of which is held by AFNOR. This document was examined by and agreed with a joint working party appointed by the Liaison Group CEN/TC 229 – CEN/TC 250, particularly for its compatibility with structural Eurocodes. 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of an identical text or by endorsement, at the latest by October 2009, and conflicting national standards shall be withdrawn at the latest by April 2012. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights. 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 EC Directive(s). For relationship with EC Directive(s), see informative Annex ZA, which is an integral part of this document. European standard for beam-and-block floor system is made of 5 parts: EN 15037-1, Precast concrete products — Beam-and-block floor systems — Part 1: Beams; EN 15037-2, Precast concrete products — Beam-and-block floor systems — Part 2: Concrete blocks; EN 15037-3, Precast concrete products — Beam-and-block floor systems — Part 3: Clay blocks; FprEN 15037-4, Precast concrete products — Beam-and-block floor systems — Part 4: Polystyrene blocks; prEN 15037-5, Precast concrete products — Beam-and-block floor systems — Part 5: Lightweight blocks. This European Standard is one of a series of product standards for precast concrete products. For common aspects of concrete products, reference is made to EN 13369, from which also the relevant requirements of the EN 206-1 are taken. The references to EN 13369 by CEN/TC 229 product standards are intended to make them homogeneous and to avoid repetitions of similar requirements. Eurocodes are taken as a common reference for design aspects. The installation of some structural precast concrete products is dealt with by ENV 13670-1, which has, at the moment, the status of a European prestandard. In all countries, it can be accompanied by alternatives for national application and it should not be treated as a European Standard. The program of standards for structural precast concrete products comprises the following standards, in some cases consisting on several parts: EN 1168, Precast concrete products — Hollow core slabs EN 12794, Precast concrete products — Foundation piles EN 12843, Precast concrete products — Masts and poles SIST EN 15037-3:2009

Where, in default of applicability conditions of EN Eurocodes to the works of destination, design provisions other than EN Eurocodes are used for mechanical strength and/or fire resistance, the conditions to affix CE marking to the product are described in ZA.3. 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 the United Kingdom.

EN 15037-3:2009 (E) 8 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 low non-resisting or non-resisting block block with no mechanical function in the final floor system (designated LNR or NR) NOTE Its only mechanical function is that of formwork during the construction of the floor system. Floor systems built with non-resisting blocks always have a cast-in-situ structural topping. 3.2 semi-resisting block block participating in the transfer of loads to the beams (designated SR) NOTE In conjunction with a cast-in-situ concrete, it may contribute to the final strength of the system. However, its top flange alone cannot act as a compression slab in the final floor system.

prEN 15037-3:2008 (E) 4 Foreword This document (prEN 15037-3:2008) has been prepared by Technical Committee CEN/TC 229 “Precast concrete products”, the secretariat of which is held by AFNOR. This document was examined by and agreed with a joint working party appointed by the Liaison Group CEN/TC 229 – CEN/TC 250, particularly for its compatibility with structural Eurocodes. This document is currently submitted to the Unique Acceptance Procedure. 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 EC Directive(s). For relationship with EC Directive(s), see informative Annex ZA, which is an integral part of this document. European standard for beam-and-block floor system is made of 3 parts: EN 15037-1, Precast concrete products — Beam-and-block floor systems — Part 1: Beams; EN 15037-2, Precast concrete products — Beam-and-block floor systems — Part 2: Concrete blocks; EN 15037-3, Precast concrete products — Beam-and-block floor systems — Part 3: Clay blocks. This European Standard is one of a series of product standards for precast concrete products. For common aspects of concrete products, reference is made to EN 13369, from which also the relevant requirements of the EN 206-1 are taken. The references to EN 13369 by CEN/TC 229 product standards are intended to make them homogeneous and to avoid repetitions of similar requirements. Eurocodes are taken as a common reference for design aspects. The installation of some structural precast concrete products is dealt with by ENV 13670-1, which has at the moment the status of a European prestandard. In all countries it can be accompanied by alternatives for national application and it should not be treated as a European Standard. The program of standards for structural precast concrete products comprises the following standards, in some cases consisting on several parts: EN 1168, Precast concrete products — Hollow core slabs EN 12794, Precast concrete products — Foundation piles EN 12843, Precast concrete products — Masts and poles EN 13224, Precast concrete products — Ribbed floor elements EN 13225, Precast concrete products — Linear structural elements EN 13693, Precast concrete products — Special roof elements EN 13747, Precast concrete products — Floor plates for floor systems EN 13978, Precast concrete products — Precast concrete garages kSIST prEN 15037-3:2008
prEN 15037-3:2008 (E) 5 EN 14843, Precast concrete products — Stairs EN 14844, Precast concrete products — Box culverts EN 14991, Precast concrete products — Foundation elements EN 14992, Precast concrete products — Wall elements EN 15037-1, Precast concrete products — Beam-and-block floor systems — Part 1: Beams EN 15050, Precast concrete products — Bridge elements EN 15258, Precast concrete products — Retaining wall elements. This European Standard defines in Annex ZA the application methods of CE marking to products designed using the relevant EN Eurocodes (EN 1992-1-1:2004 and EN 1992-1-2:2004). Where, in default of applicability conditions of EN Eurocodes to the works of destination, design provisions other than EN Eurocodes are used for mechanical strength and/or fire resistance, the conditions to affix CE marking to the product are described in ZA.3. kSIST prEN 15037-3:2008

prEN 15037-3:2008 (E) 8 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 low non-resisting or non-resisting block block with no mechanical function in the final floor system (designated LNR or NR) NOTE Its only mechanical function is that of formwork during the construction of the floor system. Floor systems built with non-resisting blocks always have a cast-in-situ structural topping. 3.2 semi-resisting block block participating in the transfer of loads to the beams (designated SR) NOTE In conjunction with a cast-in-situ concrete, it may contribute to the final strength of the system. However, its top flange alone cannot act as a compression slab in the final floor system.
